QUESTION NO: 563 An administrator is performing upgrades to ESX 4. 0 from exist 3.x and ESX 2. x hosts. Which of the following is true about this procedure? VMware VCP-410: Practice Exam "Pass Any Exam. Any Time." - www.actualtests.com 328 A. A direct, in-place upgrade can be performed only on ESX 3. 0 and later Hosts B. A direct, in-place upgrade can be performed only on ESX 2. 5 and later Hosts C. A direct, in-place upgrade can be performed only on ESX 3. 5 and later Hosts D. ESX 3.x and later Hosts can be upgradeD. but the upgrade cannot be performed in-place

Answer: A Explanation: Direct, in-place upgrade from ESX 2.5.5 to ESX 4.0 is not supported, even if you upgrade to ESX 3.x as an intermediary step. The default ESX 2.5.5 installation creates a /boot partition that is too small to enable upgrades to ESX 4.0. As an exception, if you have a non-default ESX 2.5.5 installation on which at least 100MB of space is available on the /boot partition, you can upgrade ESX 2.5.5 to ESX 3.x and then to ESX 4.0.

QUESTION NO: 80 An administrator is creating a vNetwork Standard Switch with Service Console and VMkernel networking. The administrator has two uplinks attached to the switch, but wants to separate the Service Console and VMkernel traffic to the two uplinks. Which of the following Load Balancing Policies will guarantee this, even if additional management or virtual machine traffic is added to the switch in the future? A. Use Explicit Failover B. Route based on IP hash C. Route based on source MAC hash D. Route based on the originating port ID

Answer: A Explanation: Load Balancing - Specify how to choose an uplink. Route based on the originating port ID - Choose an uplink based on the virtual port where the traffic entered the virtual switch. Route based on ip hash - Choose an uplink based on a hash of the source and destination IP addresses of each packet. For non-IP packets, whatever is at those offsets is used to compute the hash. Route based on source MAC hash - Choose an uplink based on a hash of the source Ethernet. Use explicit failover order - Always use the highest order uplink from the list of Active adapters which passes failover detection criteria.

QUESTION NO: 265 When memory is reclaimed from a virtual machine using vmmemctl, what is the maximum amount that can be reclaimed by default? A. 65% of the unreserved memory B. 65% of the configured memory C. 50% of the configured memory D. 50% of the unreserved memory

Answer: A Explanation: Memory Provisioning Recommendations for VMware Infrastructure 3 Operational Best Practices, page 11. Memory Balloon - This counter reflects the total amount of memory the VMkernel is effectively "borrowing" from virtual machines via the VMTools balloon driver running inside the guest OS. Balloon driver activity indicates over-commitment of ESX host memory. By default, the VMkernel may balloon up to 65% of a virtual machine's configure RAM.

QUESTION NO: 173 When attempting to VMotion migrate a newly built running virtual machine, the migration fails. Which of the following conditions would cause a failed migration under these conditions? A. VMI Paravirtualization Support has been enabled for the virtual machine, but is not supported on the target host B. The source host supports hyperthreading, but the target host does not C. NPIV has been enabled on the virtual machine, and VMotion is not supported with NPIV D. The number of processor cores differs between the source and target hosts

Answer: A Explanation: Migrating VMI-enabled virtual machines to platforms that do not support VMI If you have suspended a virtual machine that uses VMI on an earlier release of a VMware product, you cannot resume the virtual machine on a VMware product which does not support VMI. You cannot vMotion VMI-enabled virtual machines from earlier releases to future products that do not support VMI. Instead, use cold migration to transition the VMI-enabled virtual machine to a future VMware product. Power the virtual machine off and then power it back on in the future VMware product.

QUESTION NO: 406 In a fully automated DRS cluster, what can be done to ensure that a specific virtual machine (VM) does not migrate automatically to another host? A. set the DRS VM options report_section = "8" for the specific VM to Partially Automated B. use the Affinity Wizard to specify manual automation C. do nothing because the DRS cluster must be put in Partially Automated mode to allow this level of control D. set the DRS VM rule to "keep on this host"

Answer: A Explanation: Need help to find the setting Report_Section = "8" in VC This DRS settings is made to be added in the "Edit Settings" of a cluster on the Tab "Summary" go to "VmWare DRS" and on the down right corner you have "Advanced Options", when opened, you have a row "Option" and a row "Value" "report_section" is to be put in "Option" row and the "8" is to be put in Value. It apparently stops Vmotioning between all nodes of the cluster.

QUESTION NO: 261 When creating an MSCS Cluster across 2 ESX 4 Hosts, what type of Virtual Disks can be used? A. Raw Device Mapped (RDM) disks in Physical or Virtual Compatibility Mode B. Raw Device Mapped (RDM) disks in Physical or Virtual Compatibility Mode, or virtual disks on a shared VMFS datastore C. Raw Device Mapped (RDM) disks in Virtual Compatibility Mode only D. Raw Device Mapped (RDM) disks in Physical Compatibility Mode only

Answer: A Explanation: Setup for Failover Clustering and Microsoft Cluster Service ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 19. You can create a MSCS cluster that consists of two virtual machines on two ESX/ESXi hosts. Prerequisites A cluster across physical hosts requires specific hardware and software. ESX/ESXi hosts that have the following: Two physical network adapters dedicated to the MSCS cluster and to the public and private networks. One physical network adapter dedicated to the service console (ESX hosts) or the VMkernel (ESXi hosts). Fibre Channel (FC) SAN. Shared storage must be on an FC SAN. RDM in physical compatibility (pass-through) or virtual compatibility (non-pass-through) mode. Vmware recommends physical compatibility mode. The cluster cannot use virtual disks for shared storage.

QUESTION NO: 384 A user has been given access to VirtualCenter using the Virtual Infrastructure Client to administer virtual machines. What else can the user do? A. log on to the VirtualCenter server B. log on to any ESX Server managed by VirtualCenter C. log on to the VirtualCenter server if an administrator grants the Permit Web Access privilege D. log on to the VirtualCenter server and any ESX Server managed by VirtualCenter

Answer: A Explanation: Since the user has been given access to vCenter using the vSphere Client then as a minimum they must be allowed to log on to vCenter server, since this is required to manage virtual machines. Once logged on, they may then manage virtual machines, (C above). Access to vCenter does not grant any access directly to ESX hosts, so B and D are incorrect. Permit Web Access is not required when accessing vCenter, so C is incorrect..

QUESTION NO: 307 What is the maximum amount of Hosts per vSphere HA Cluster? A. 32 B. 16 C. 8 D. 64

Answer: A Explanation: Table Resource Pool Maximums Hosts per HA cluster32

QUESTION NO: 566 A Windows virtual machine (VM) viewed through Task Manager shows CPU utilization averaging 95-100%. What metric shoule be checked to ensure this VM is not in contention for CPU resources with other VMs on the same ESX Host? A. CPU Ready B. CPU Wait C. CPU Usage D. CPU Overhead

Answer: A Explanation: The VM is utilizing most of the CPU resources allocated to it. The CPU Ready value should be checked to determine if this is a resource constraint.

QUESTION NO: 178 Company X wants to install Application Y in a virtualized environment. The underlying operating system has to be Windows 2003 SP1. In a physical environment, the application and supporting software have very strict minimum hardware requirements. Which requirement(s) would prohibit the use of this application inside a virtual machine? A. a minimum disk size of 2 TB B. a minimum of 4 available SCSI adapters C. 3 NICs and 3 SCSI adapters D. 4 CPUs and 4.5 GB RAM

Answer: A Explanation: The max size of a virtual disk is 2TB minus 512B, "a minimum disk size of 2 TB" cannot be met. "a minimum of 4 available SCSI adapters" is possible because ESX 4 supports up to 4 SCSI adapters per virtual machine. "4 CPUs and 4.5 GB RAM "is possible because up to 8 CPUs and 255GB RAM are allowed per virtual machine. "3 NICs and 3 SCSI adapters" is also possible because the number of virtual PCI slots was increased to allow for the configuration maximums as specified in the following URL. http://www.vmware.com/pdf/vsphere4/r40/vsp_40_config_max.pdf While "3 NICs and 3 SCSI adapters" would be true for hardware revision 4 because it had 5 free virtual PCI slots, hardware revision 7 does not have that limitation. This practice exam is for vSphere 4 and the question does not specify which hardware version.

QUESTION NO: 263 A Windows virtual machine (VM) is experiencing poor application performance. The suspected issue is a lack of available memory. Windows Task Manager shows 30% of the memory within the VM is not currently being used. What does this indicate and what could be checked next? A. The VM has memory available, however it may not actually have physical memory available. VMkernel swap activity on the ESX Server host should be checked next. B. Windows Task Manager is not reading actual memory usage in the VM. Windows System Monitor should be used to get a precise reading on memory usage. C. The application problems are definitely due to a non-memory related problem. CPU affinity settings should be checked for this VM. D. The application problems are definitely due to a non-memory related problem. CPU utilization should be checked next using Windows Task Manager.

Answer: A Explanation: The poor application performance due to suspected lack of available memory suggests paging is the cause of the issue. If Windows Task Manager shows 30% of the memory within the VM is not currently being used, then paging must be occurring within the VM host. Therefore poor application performance should now be checked.

QUESTION NO: 5 When installing ESX 4.0, where is the Service Console file system located? A. In a virtual disk on a local VMFS datastore B. In a virtual disk on a local or shared VMFS datastore C. On a local physical disk or on a mapped SAN LUN D. On a local physical disk

Answer: A Explanation: The reason for this is the fact that the service console is a VMDK. This VMDK is stored on the local VMFS volume by default in the following location: esxconsole-/esxconsole.vmdk. Everyone at this point should be aware that the Service Console is now located in a vmdk on a VMFS partition. The Service Console vmdk must be stored on a vmfs datastore and the datastore must either be local storage or SAN storage that is only presented to the one host

QUESTION NO: 367 A VM using VMDirectPath I/O cannot be VMotioned? A. True B. False

Answer: A Explanation: VMDirectPath I/O for virtual machines. Enhance CPU efficiency for applications that require frequent access to I/O devices by allowing select virtual machines to directly access underlying hardware devices. Other virtualization features, such as VMware VMotion™, hardware independence and sharing of physical I/O devices will not be available to the virtual machines using this feature

QUESTION NO: 241 Which of the following is true regarding backups created with VMware Data Recovery? A. Backups of ESX 3.x VMs take longer than backups of ESX 4 VMs B. Backups of ESX 3.x and later VMs take the same amount of time to complete C. Backups of ESX 3.0 VMs are not supported, but ESX 3.5 VMs are supported D. Backups of ESX 3.x VMs are not supported

Answer: A Explanation: VMware Data Recovery Administration Guide Data Recovery 1.1, page 8. For virtual machines created in vSphere 4.0, the Data Recovery appliance creates a quiesced snapshot of the virtual machine during the backup. The backups use the changed block tracking functionality on the ESX hosts. For each virtual disk being backed up, it checks for a prior backup of the virtual disk. It uses the change-tracking functionality on ESX hosts to obtain the changes since the last backup. The deduplicated store creates a virtual full backup based on the last backup image and applies the changes to it. NOTE These optimizations do not apply to virtual machines created with VMware products prior to vSphere 4.0. For example, change tokens are not used with virtual machines created with Virtual Infrastructure 3.5 or earlier. As a result, virtual machines created with earlier VMware versions take longer to back up

QUESTION NO: 247 What is the maximum number of backup or restore jobs that VMware Data Recovery can run concurrently? A. 8 B. 4 C. 16 D. 2

Answer: A Explanation: VMware Data Recovery Administrator's Guide, page 7. Backing Up Virtual Machines During a backup, Data Recovery creates a quiesced snapshot of the virtual machine. Deduplication is automatically performed with every backup operation. Data Recovery can concurrently back up a maximum of eight virtual machines. To start multiple backups, CPU utilization must be less than 90 percent.

QUESTION NO: 245 What is the technology VMware Data Recovery uses to back up a Windows 2003 virtual machine? A. Volume Shadow Copy Service B. LGTO SYNC driver C. EMC Autostart Manager D. Crash-consistent quiescing

Answer: A Explanation: VMware Data Recovery. VSS support. Supports Volume Shadow Copy Service (VSS) to enable consistent backups of virtual machines running Microsoft operating systems and applications.

QUESTION NO: 35 An administrator is installing an ESX Host to boot from a SAN LUN. The storage array is an active/passive array. After configuring the boot LUN and installing ESX, the system does not boot properly.Which of the following could cause this issue? A. The Storage Processor port specified in the BIOS configuration of the HBA is passive B. The LUN specified in the BIOS configuration of the HBA is active C. The Storage Processor port specified in the BIOS configuration of the HBA is active D. The LUN specified in the BIOS configuration of the HBA is passive

Answer: A Explanation: VMware ESX Server SAN Configuration Guide, page 60. When you boot from an active-passive storage array, the storage processor whose world wide name (WWN) is specified in the BIOS configuration of the HBA must be active. If the storage processor is passive, the QLogic adapter cannot support the boot process.

QUESTION NO: 530 An administrator is installing an ESX Host to boot from a SAN LUN. During installation, the ESX drivers are unable to detect the HBA. Which of following could be the issue? A. The HBA BIOS is not enabled B. The HBA is connected to a SAN using a direct connect topology C. The HBA is not plugged into the lowest PCI bus and slot number D. The HBA is connected to an active/passive storage array, but the configured port

Answer: A Explanation: VMware ESX Server SAN Configuration Guide, page 61. ESX Server Configuration Requirements for Booting from SAN * The HBA BIOS for your QLogic HBA Fibre Channel card must be enabled and correctly configured to access the boot LUN. * The booting logical unit number (LUN) must be visible from the lowest numbered HBA that has any visible LUNs. * The boot LUN must be visible from the lowest numbered storage processor (attached to that HBA) that has any visible LUNs. * The boot LUN must be the lowest numbered LUN attached to that storage processor (except for gatekeeper LUNs which are sometimes assigned LUN0). * You must remove all internal SCSI drives for all servers. * HBA numbers can change automatically when you add and remove PCI adapters, or manually when you edit the /etc/vmware/devnames.conf file. The HBA must be set to the lowest PCI bus and slot number. This enables it to be detected very quickly since the drivers scan the HBAs in ascending PCI bus and slot numbers, regardless of the associated virtual machine HBA number. * If you are running an IBM eServer BladeCenter and boot from SAN, you must disable IDE drives on the blades.

QUESTION NO: 33 Installing additional software in the ESX Service Console is supported in which of the following instances? A. for hardware management support B. for improved utilization of the ESX host resources C. for graphical desktop access for administrative purposes D. for enhanced virus protection

Answer: A Explanation: VMware ESX Server Third-Party Software in the Service Console, page 4 The only circumstance in which you might have to resort to running the software within the ESX Server service console is when you require direct access to hardware.

QUESTION NO: 390 A company decides to replace one 8-CPU host with four dual-CPU hosts. This Virtual Infrastructure uses server-based licensing. How many new licenses will be required? A. 0 B. 4 C. 8 D. 16

Answer: A Explanation: VMware Multi-Core Pricing & Licensing Policy How does this policy affect my licensing costs on servers with less than 6 cores per processor? When upgrading your hardware to multi-core technology, you do not need to pay additional licensing fees for a processor with up to 6-cores per processor. For example, if you purchase a two-socket server with each socket populated with a 6-core processor, you need to purchase only two processor licenses of VMware vSphere or related products for that server. Under the original configuration an 8-CPU host requires (8 x 1) 8 CPU licenses. Under the new configuration four dual-CPU hosts requires (4 x 2) 8 CPU licenses.

QUESTION NO: 237 What function does VMware Enhanced VMotion Compatibility provide? A. The ability to VMotion virtual machines between CPUs with a common supported baseline B. The ability to VMotion virtual machines between Intel and AMD processors C. The ability to VMotion virtual machines between ESX Hosts with different core counts D. The ability to VMotion virtual machines between CPUs with hardware virtualization and CPUs without this support

Answer: A Explanation: VMware VMotion and CPU Compatibility VMware Enhanced VMotion Compatibility (EVC) facilitates VMotion between different CPU generations. When enabled for a cluster, EVC ensures that all CPUs within the cluster are VMotion compatible.

QUESTION NO: 424 Virtual machine (VM) A is connected to virtual switch A, and VM B is connected to virtual switch B. Which statement is true about the network traffic between A and B? A. Traffic between VM A and VM B flows through the physical NIC. B. Traffic between VM A and VM B stays within ESX Server. C. VM A can communicate with VM B if they have same security policies. D. VM A can communicate with VM B if they have same port group policies.

Answer: A Explanation: VMware Virtual Networking Concepts, page 5. Network traffic cannot flow directly from one virtual switch to another virtual switch within the same host. Therefore an external switch is required.

QUESTION NO: 52 Assuming VLANs are not configured, which of the following is true about traffic from a virtual machine connected to a port group on a vNetwork Standard Switch with no uplinks? A. Virtual machines in any port group on the virtual switch can receive the traffic B. The virtual switch will drop the packets if no uplink is present C. Virtual machines on any virtual switch on the same ESX/ESXi host can receive the traffic D. Only virtual machines in the same port group on the virtual switch can receive the traffic

Answer: A Explanation: VMware Virtual Networking Concepts, page 6. It is possible, and even reasonable, to assign the same VLAN ID to multiple port groups. This would be useful if, for example, you wanted to give different groups of virtual machines different physical Ethernet adapters in a NIC team for active use and for standby use, while all the adapters are on the same VLAN. Since a port group without an assigned VLAN has an implicit VLAN ID of 0, all port groups without a VLAN ID will be in VLAN0. Multiple port groups with the same VLAN can communicate with each other. Physical Ethernet adapters serve as bridges between virtual and physical networks. In VMware Infrastructure, they are called uplinks, and the virtual ports connected to them are called uplink ports. If no uplink exists there will be no communication with physical networks, but traffic will propagate across virtual interfaces connected to the same switch.

QUESTION NO: 387 A company decides to use a license server for a newly installed Virtual Infrastructure. The infrastructure consists of one VirtualCenter server and two ESX Server hosts, each with two dual core CPUs. DRS, VMware HA and VMotion will be used on all hosts.How many license files need to be installed on the license server? A. 1 B. 2 C. 4 D. 7 E. 25

Answer: A Explanation: VMware: Combining .lic license files. As you may know, the license server for VI3 (provided by FlexLM) can only use 1 license file. This file is called vmware.lic and is stored (latest version) in C:\Program Files\VMware\VMware License Server.

QUESTION NO: 56 Which of the following describes the default behavior of uplinks added to a vNetwork Standard Switch? A. All uplinks are active B. The first uplink is active, additional uplinks are standby C. The first uplink is active, additional uplinks are unused D. Only one uplink can be attached to a virtual switch

Answer: A Explanation: When an uplink port is added, it defaults to the Active Adapters group, as below.

QUESTION NO: 431 In which format does an iSCSI target ID appear? A. iqn.<year-mo>.<reversed_domain_name>:<unique_name> B. iscsi.<year-mo>.<forward_domain_name>:<unique_name> C. iqn.<ip_address>.<reversed_domain_name> D. iscsi.<organizational_unit>.<forward_domain_name>:<unique_name>

Answer: A Explanation: Wikipedia - iSCSI Addressing Special names refer to both iSCSI initiators and targets. iSCSI provides three name-formats:

QUESTION NO: 26 Securing an ESX service console is important because? A. Service Console actions can affect all VMs on an ESX host B. Service Console permissions are applied to users when logging in to a host via vCenter C. VMs run in the service console D. VMs depend on the patch level of the service console

Answer: A Explanation: With VMware ESX being loaded on top of the server hardware, there are a few points of immediate concern: These two pieces are two very distinct parts of VMware ESX. VMware has periodically released patches for both of these different components although you probably just thought of them as "ESX patches". Concerning #1, the VMKernel and its virtualization layer is extremely secure. The Guest machines have hardware isolation in place and it seems impossible that a guest VM could somehow compromise the security of the host virtualization layer. As for #2, with the services console being based on Linux, it will be affected by most of the Red Hat Linux vulnerabilities. Because the service console is a Linux OS with a direct link to the VMKernel, I will focus on securing the service console

QUESTION NO: 440 Which security technology does VMware iSCSI use? A. CHAP B. AES C. IPSec D. PAP E. MSCHAPv2

Answer: A Explanation: iSCSI SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 37. Because the IP networks that the iSCSI technology uses to connect to remote targets do not protect the data they transport, you must ensure security of the connection. iSCSI requires that all devices on the network implement Challenge Handshake Authentication Protocol (CHAP), which verifies the legitimacy of initiators that access targets on the network.

QUESTION NO: 37 What is the proper LUN Masking configuration for LUNs presented to an ESX Host when using the Boot from SAN option? A. The Boot LUN should be masked so that only one ESX Host can see the LUN, while the datastore LUNS should be masked so that all ESX Hosts can see the LUNs B. The Boot LUN and datastore LUNS should be masked so that all ESX Hosts can see the LUNs C. The Boot LUN should be masked so that all ESX Hosts can see the LUN, while the datastore LUNS should be masked so that only one ESX Host can see the LUNs D. The Boot LUN and datastore LUNS should be masked so that only one ESX Host can see the LUNs

Answer: A Explanation: iSCSI SAN Configuration Guide, page 14, 52. Boot LUNs should only be visible to the server using that LUN to boot. No other server or system on the SAN should be permitted to see that boot LUN. ESX/ESXi and SAN Use Cases. You can perform a number of tasks when using ESX/ESXi with SAN. Using ESX/ESXi in conjunction with SAN is effective for the following tasks: Maintenance with zero downtime When performing an ESX/ESXi host or infrastructure maintenance, use VMware DRS or VMotion to migrate virtual machines to other servers. If shared storage is on the SAN, you can perform maintenance without interruptions to the user. Load balancing Use VMotion or VMware DRS to migrate virtual machines to other hosts for load balancing. If shared storage is on a SAN, you can perform load balancing without interruption to the user. To enable this functionality, shares storage is required - hence the datastore LUNS should be masked so that all ESX Hosts can see the LUNs

QUESTION NO: 93 How are new LUNs discovered by an ESX Host? A. A rescan operation is required every time a new LUN is added B. ESX Server automatically detects new LUNs as they are presented C. ESX Server periodically performs a rescan operation to detect any new LUNs D. A reboot operation is required to detect newly presented LUNs

QUESTION NO: 286 A new ESX Server is set up initially with two virtual machines (VMs) for users to access. The applications running in the virtual machines can take advantage of all Available Memory in the VM. 20 additional VMs with the same application will be installed within six months, which may lead to memory contention on the ESX Host. How can the first two VMs be configured so that their performance remains equal to the future VMs that will be deployed? A. set a memory limit on the VMs that is a lower value than the Available Memory for the VMs B. set the memory shares so that the VMs get 10 shares per megabyte of configured memory for the VMs C. set an expandable memory reservation on the VM that is lower than 50% of the configured memory for the VMs D. set a memory reservation on the VMs that is lower than 50% of the Available Memory for the VMs

Answer: A Explanation: vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 24. At present each virtual machine will potentially gain access to 50% of the available physical memory. Once the additional 20 virtual machines have been provisioned, each virtual machine will average approximately 4% of the available physical memory. A memory limit is an upper bound on the amount of physical memory that the host can allocate to the virtual machine. The virtual machine's memory allocation is also implicitly limited by its configured size. Therefore if a memory limit is imposed, it could be used to limit the available memory to a similar value to that available once the additional 20 virtual machines are added.

QUESTION NO: 579 The VMkernel is secured using which of the following techniques (Choose Two)? A. Kernel Module Integrity B. Memory Hardening C. Binary Translation D. Service Console Firewall

Answer: A,B Explanation: Memory Hardening - The ESX/ESXi kernel, user-mode applications, and executable components such as drivers and libraries are located at random, non-predictable memory addresses. Combined with the nonexecutable memory protections made available by microprocessors, this provides protection that makes it difficult for malicious code to use memory exploits to take advantage of vulnerabilities. Kernel Module Integrity - Digital signing ensures the integrity and authenticity of modules, drivers and applications as they are loaded by the VMkernel. Module signing allows ESXi to identify the providers of modules, drivers, or applications and whether they are VMware-certified. Trusted Platform Module (ESXi ONLY and BIOS enabled) - This module is a hardware element that represents the core of trust for a hardware platform and enables attestation of the boot process, as well as cryptographic key storage and protection. Each time ESXi boots, TPM measures the VMkernel with which ESXi booted in one of its Platform Configuration Registers (PCRs). TPM measurements are propagated to vCenter Server when the host is added to the vCenter Server system.

QUESTION NO: 120 What are two benefits of Virtual Compatibility Mode for RDMs, as compared to Physical Compatibility Mode (Choose Two)? A.

Mask the NX/XD bit in the Processor section of the Configuration tab on the ESX Hosts D. Enable Rapid Virtualization Indexing

Answer: A,B Explanation: vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 153. Select Advanced > CPUID Mask. OSpecify whether you want to hide the host's CPU NX flag from the guest operating system Hiding the NX flag prevents the guest operating system from making use of this CPU feature, but enables the virtual machine to be moved to hosts that do not include the NX feature. When the NX flag is visible, the guest operating system can make use of the feature, but the virtual machine can be moved only to hosts with the NX capability. Enhanced VMotion Compatibility (EVC) processor support Enhanced VMotion Compatibility (EVC) simplifies VMotion compatibility issues across CPU generations. EVC automatically configures server CPUs with Intel FlexMigration or AMD-V Extended Migration technologies to be compatible with older servers. After EVC is enabled for a cluster in the VirtualCenter inventory, all hosts in that cluster are configured to present identical CPU features and ensure CPU compatibility for VMotion. The features presented by each host are determined by selecting a predefined EVC baseline.

CPUs with the same clock speed and cache size must exist on both the source and destination hosts

Answer: A,B Explanation: vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0Page 48. VMotion Requirements To enable the use of DRS migration recommendations, the hosts in your cluster must be part of a VMotion network. If the hosts are not in the VMotion network, DRS can still make initial placement recommendations. To be configured for VMotion, each host in the cluster must meet the following requirements: The virtual machine configuration file for ESX/ESXi hosts must reside on a VMware Virtual Machine File System (VMFS). VMotion does not support raw disks or migration of applications clustered using Microsoft Cluster Service (MSCS). VMotion requires a private Gigabit Ethernet migration network between all of the VMotion enabled managed hosts. [B above]. Whilst it may not be an absolute requirement that virtual machines must have access to the same subnets on the source and destination hosts for VMotion to occur, if virtual machines do not have this access, then they can no longer communicate, thus rendering a VMotion migration un successful. [A is correct]. VMware VCP-410: Practice Exam "Pass Any Exam. Any Time." - www.actualtests.com 149 Processor Compatibility VMotion compatibility means that the processors of the destination host must be able to resume execution using the equivalent instructions where the processors of the source host were suspended.

VMFS also features failure consistency and recovery mechanisms, such as distributed journaling, a failure consistent virtual machine I/O path, and machine state snapshots. These mechanisms can aid quick identification of the cause and recovery from virtual machine, physical host, and storage subsystem failures [B above] What Is New in VMware vSphere™ 4: Storage, page 7. vSphere introduces several new capabilities to Storage VMotion. When Storage VMotion was introduced in VI3 release 3.5, it had a few limitations which vSphere 4 addresses. Storage VMotion is now fully integrated into vCenter and offers full support for migration across datastores of several protocol choices. Hence the enhanced Storage VMotion capabilities fall squarely in the realm of how vSphere provides an increased set of choices. First the ability to move a VM home from one datastore to another while changing the storage protocol in the process. The source datastore might be FC, iSCSI, or NFS, and the target datastore any of those three. [C above]

QUESTION NO: 112 By default, VMware supports the following Path Selection Policies (Choose Three)? A. Fixed B. MRU (Most recently used) C. Least Busy D. Round Robin E. Least I/O

Answer: A,B,D Explanation: A "Multivendor Post" on using iSCSI with VMware vSphere When it comes to path selection, bandwidth aggregation and link resiliency in vSphere, customers have the option to use one of VMware's Native Multipathing (NMP) Path Selection Policies (PSP), 3rd party PSPs, or 3rd party Multipthing Plug-ins (MPP) such as PowerPath V/E from EMC. VMware ships with a set of native SATPs, and 3 PSPs: Fixed, Most Recently Used (MRU), & Round Robin (RR). Fixed and MRU options were available in VI3.x and should be familiar to readers. Round Robin was experimental in VI3.5, and is supported for production use in vSphere (all versions)

QUESTION NO: 432 Click the Exhibit button -vmhba manage paths. Given the information shown in the exhibit, which three statements are true? (Choose three.) Note: This server has not been modified from the default configuration A. LUN has four paths. B. LUN is on an Active/Passive array. C. Preferred Path is vmhba2:2:0. D. HBA Failover occurred. E. LUN is on an Active/Active array.

Answer: A,B,D Explanation: Fibre Channel SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 52, 53, 63, 64 Understanding Storage Device Naming Runtime Name The name of the path to the device. The runtime name is created by the host. The name is not a reliable identifier for the device, and is not persistent. Since there are 4 entries, there are 4 paths. [A above] With both active/active and active/passive storage arrays, you can set up your host to use different paths to different LUNs so that your adapters are being used evenly. Since the Status shows Active for the first entry and Passive for the remainder, the LUN is on an Active/Passive array. [B is correct, and therefore E is incorrect.] Active/passive arrays use the MRU path policy which does not have a preferred path. Therefore C is incorrect. Runtime Name - The name of the first path to the device. Since the Runtime Name is vmhba3:0:0 (from the top of the dialog box), and the active device is vmhba2:2:0 then it can be assumed that an HBA Failover occurred. Therefore D is correct.

Answer: A,B,E Explanation: Ensure that the hardware and/or virtual machine meets the minimum system requirements for VMware vCenter 4.0 You can use vSphere Host Update Utility to upgrade ESX 3.x to ESX 4.0 and ESXi 3.5 hosts to ESXi 4.0. You cannot use vSphere Host Update Utility to convert ESX hosts to ESXi hosts, or the reverse. When you select a host to be upgraded, the tool performs an automated host compatibility check as a preupgrade step. The check verifies that each host is compatible with ESX 4.0/ESXi 4.0, including the required CPU, and has adequate boot and root partition space. In addition to the automated preupgrade script, you can specify a postupgrade configuration script to ease deployment. Note the preupgrade script is automated and so does not need to be run explicitly. ESX and vCenter Server Installation Guide, ESX 4.0 vCenter Server 4.0, page 13.

QUESTION NO: 88 A virtual machine is using a Fibre Channel attached Raw Device Mapped (RDM) LUN. Which of the following applications used with the virtual machine would require the RDM to be in Physical Compatibility Mode (Choose Three)? A. SAN Management Agents B. Physical Server to Virtual Machine Clustering C. Storage Array based Replication D. VMware Snapshots E. SCSI-target based software

Answer: A,B,E Explanation: Setup for Failover Clustering and Microsoft Cluster Service ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 25. Cluster Physical and Virtual Machines A standby host cluster has specific hardware and software requirements. Use RDMs in physical compatibility mode (pass-through RDM). You cannot use virtual disks or RDMs in virtual compatibility mode (non-pass-through RDM) for shared storage. [B is correct]. Physical compatibility mode allows the guest operating system to access the hardware directly. Physical compatibility is useful if you are using SAN-aware applications in the virtual machine. However, a virtual machine with the physical compatibility RDM cannot be cloned, made into a template, or migrated if the migration involves copying the disk. Virtual compatibility allows the RDM to behave as if it were a virtual disk, so you can use such features as snapshotting, cloning, and so on. [Therefore D is incorrect]. Recommended Detailed Material on RDM's Physical mode for the RDM specifies minimal SCSI virtualization of the mapped device, allowing the greatest flexibility for SAN management software. In physical mode, the VMkernel passes all SCSI commands to the device, with one exception: the REPORT LUNs command is virtualized, so that the VMkernel can isolate the LUN for the owning virtual machine. Otherwise, all physical characteristics of the underlying hardware are exposed. Physical mode is useful to run SAN management agents [B above] or other SCSI target based software [E above] in the virtual machine.

The settings affect all vSwitch traffic. C. The settings are defined on a per port group basis. D. The settings affect only traffic coming into the uplink adapter from the physical network. E. The settings are defined on a per-virtual machine basis.

Answer: A,C Explanation: "defined on a per port group basis. " could be considered a correct answer because according to the VMWare Infrastructure 3:Install and Configure guide, "Traffic shaping may be defined at the virtual switch OR Port Group level. " The important distinction here is that they can be defined at this level, but they are APPLIED on a per-virtual machine basis or more directly, to the VM's virtual NIC's.

QUESTION NO: 28 ESX Service Console patches should be applied (Choose Two)? A. in accordance with VMware Security Advisories B. when notified on the VMware Security Blog C. when advised by VMware authorized technical support personnel D. in accordance with VMware and RedHat Security Advisories

If you haven't been notified about patches, you can check the ESX Patch update site to get the latest patch info Patches will be either for security reasons, critical bug fix issues, or general system bugs. Of course, security and critical bug fix patches should be applies as soon as possible. Many of the ESX Server patches are actually for the service console (based on Red Hat Enterprise Linux). Although, don't try to apply Red Hat patches to the service console as you will find out that they don't work.

QUESTION NO: 285 It appears that a virtual machine (VM) in a DRS Cluster is having performance problems because it does not have enough CPU resources available. Which of the following methods could be used to improve performance and reduce CPU contention of this VM while maintaining compatibility with DRS (Choose Two)? A. set the CPU reservation for this VM to the Average CPU Utilization and the CPU limit for this VM to Peak CPU Utilization B. set the CPU reservation for this VM to 100% C. increase CPU shares for this VM to High D. set CPU affinity on the VM

Answer: A,C Explanation: Assume the VMs CPU usage on the host looks like this currently Assume the cluster has 4000 GHz total CPU available, and that currently the VM has 1000 MHz reserved to it, and peaks at 2000 MHz. vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 155. The values Low, Normal, High, and Custom are compared to the sum of all shares of all virtual machines on the server. Therefore if you increase CPU shares for this VM to High, it will gain proportionally more resources, improve performance and reduce CPU contention. Therefore A is correct. If you set the CPU reservation for this VM to the Average CPU Utilization, (which will be a value between 1000 MHz and 2000 MHz) and the CPU limit for this VM to Peak CPU Utilization 2000 MHz. This will cause the VM to gain additional resources, and should improve performance. Therefore B is correct. Affinity rules In general, don't specify affinity rules unless you have specific reasons to do so. This will give DRS the maximum flexibility to consider all options for resource management and hence enable the most efficient resource placement. Setting CPU affinity will not increase available resources. Therefore D is incorrect. Resource Management and DRS Best Practices The following guidelines can help you achieve optimal performance for your virtual machines: When specifying the reservations for virtual machines, always leave some headroom; do not commit all resources. As you move closer to fully reserving all capacity in the system, it becomes increasingly difficult to make changes to reservations and to the resource pool hierarchy without violating admission control. In a DRS-enabled cluster, reservations that fully commit the capacity of the cluster or of individual hosts in the cluster can prevent DRS from migrating virtual machines between hosts. Therefore B is incorrect.

QUESTION NO: 121 Which of the following are accurate descriptions of the Predictive and Adaptive Schemes for placing VMFS datastores (Choose Two)? A. The Predictive Scheme utilizes several LUNs with different storage characteristics B. The Predictive Scheme utilizes a small number of large LUNs C. The Adaptive Scheme utilizes a small number of large LUNs D. The Adaptive Scheme utilizes several LUNs with different storage characteristics

Answer: A,C Explanation: Making LUN Decisions. In the predictive scheme, you: · Create several LUNs with different storage characteristics. (B above) · Build a VMFS volume in each LUN (label each volume according to its characteristics). ·Locate each application in the appropriate RAID for its requirements. ·Use disk shares to distinguish high-priority from low-priority virtual machines. Note that disk shares are relevant only within a given ESX Server host. The shares assigned to virtual machines on one ESX Server host have no effect on virtual machines on other ESX Server hosts. In the adaptive scheme, you: ·Create a large LUN (RAID 1+0 or RAID 5), with write caching enabled. (A above) ·Build a VMFS in that LUN. ·Place four or five virtual disks on the VMFS. ·Run the applications and see whether disk performance is acceptable. If performance is acceptable, you can place additional virtual disks on the VMFS. If it is not, you create a new, larger LUN, possibly with a different RAID level, and repeat the process. You can use cold migration so you don't lose virtual machines when recreating the LUN.

Virtualized MMU is required for the vmmemctl driver C. Virtualized MMU is required for Virtual Machine Direct Path PCI devices D. Virtualized MMU enables memory reclamation from the guest OS

Answer: A,C Explanation: Standardized but Flexible I/O for Self-Virtualizing Devices Hypervisors which support assigning PCI functions to VMs have to provide a virtual PCI (vPCI) bus for each VM so that the guest OS in the VM can discover the assigned PCI devices. Typically the following steps are performed: 1. A device is chosen from the PCI bus to be assigned to a VM. 2. The OS/hypervisor arranges for the device's interrupts to be forwarded to the VM. 3. The OS/hypervisor configures the IO-MMU to permit the device to access the VM's memory. [C above] 4. The OS/hypervisor attaches the device to a VM's vPCI bus. 5. The guest OS discovers the device on its vPCI bus, and loads the device's PCI driver.

QUESTION NO: 91 When writes from a virtual machine are delivered to a Fibre Channel Storage Array, which of the following actions is taken by the VMkernel (Choose Three)? A. The file corresponding to the virtual machine is located on the VMFS datastore B. The I/O request is converted from binary data form to optical form C. The modified I/O request is sent from the device driver to the physical HBA D. The request for blocks on the virtual disk is mapped to blocks on the appropriate physical device E. The commands are forwarded by the virtual SCSI Controller

Answer: A,C,D Explanation: Fibre Channel SAN Configuration Guide ESX Server 3.5, ESX Server 3i version 3.5 VirtualCenter 2.5, page 40. When a virtual machine interacts with a SAN, the following process takes place: When the guest operating system in a virtual machine needs to read or write to SCSI disk, it issues SCSI commands to the virtual disk. Device drivers in the virtual machine's operating system communicate with the virtual SCSI controllers. VMware ESX Server supports two types of virtual SCSI controllers: BusLogic and LSILogic. The virtual SCSI Controller forwards the command to the VMkernel. The VMkernel: Locates the file in the VMFS volume that corresponds to the guest virtual machine disk. Maps the requests for the blocks on the virtual disk to blocks on the appropriate physical device. Sends the modified I/O request from the device driver in the VMkernel to the physical HBA (host HBA). The host HBA: Converts the request from its binary data form to the optical form required for transmission on the fibre optic cable. Packages the request according to the rules of the FC protocol. Transmits the request to the SAN. Depending on which port the HBA uses to connect to the fabric, one of the SAN switches receives the request and routes it to the storage device that the host wants to access.

QUESTION NO: 124 vCenter Server allows you to centrally manage hosts and use which of the following services that would otherwise be unavailable (Choose Three)? A. High Availability (HA) B. Resource Pools C. Distributed Resource Scheduler (DRS) D. Data Recovery E. Host Health Status

QUESTION NO: 45 Which of the following files are part of a typical virtual machine? A. BIOS File (.nvram) B. VMotion Transfer File (.vmt) C. Configuration File (.vmx) D. Virtual Disk File (.vmdk) E. Hardware File (.svr)

Answer: A,C,D Explanation: VMware File Extensions VMDK -- These files are the actual hard disk of the virtual machine itself, and tend to be the largest file within the folder. You can consider the size of this file to be roughly equivalent to the size of either the disk itself (if you've chosen to use preallocated disks) or the size of the data currently stored on that disk (if you use growable disks). [D above] NVRAM -- Consider this file the BIOS of the virtual machine. [A above] VMX -- With typically one VMX file per folder, this file holds the configuration information for the virtual machine in a text format. [C above] VMXF -- This file, in XML format, includes additional information about the virtual machine if it has been added to a team. If a machine has been added to a team and then later removed, this file remains resident. This file can also be opened and read in a text editor. VMTM -- For virtual machines actively participating in a team, this file stores information about that team membership. VMEM -- These files, which contain a backup of the VMs paging file, are typically very small or non-existent when the virtual machine is powered off, but grow immediately to the size of configured RAM when the machine is powered on. VMSN and .VMSD -- When snapshots are created for a virtual machine, these files are created to host the state of the virtual machine. VMSS -- If you've suspended the state of your machine, this file contains the suspended state of that machine. These files typically only appear when virtual machines have been suspended. HLOG -- If you have vMotioned the Virtual Machine, this file is created and can be safely deleted.

QUESTION NO: 232 Which of the following are benefits of using resource pools (Choose Two)? A. access control and delegation B. decreased virtualization overhead C. isolation between pools, sharing within pools D. improved network utilization E. flexible hierarchical organization F. isolation within pools, sharing between pools

Answer: A,C,E Explanation: vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 36. Why Use Resource Pools? Resource pools allow you to delegate control over resources of a host (or a cluster), but the benefits are evident when you use resource pools to compartmentalize all resources in a cluster. Create multiple resource pools as direct children of the host or cluster and configure them. You can then delegate control over the resource pools to other individuals or organizations. Using resource pools can result in the following benefits. Flexible hierarchical organization—Add, remove, or reorganize resource pools or change resource allocations as needed. Isolation between pools, sharing within pools—Top-level administrators can make a pool of resources available to a department-level administrator. Allocation changes that are internal to one departmental resource pool do not unfairly affect other unrelated resource pools. Access control and delegation—When a top-level administrator makes a resource pool available to a department-level administrator, that administrator can then perform all virtual machine creation and management within the boundaries of the resources to which the resource pool is entitled by the current shares, reservation, and limit settings. Delegation is usually done in conjunction with permissions settings.

QUESTION NO: 211 Assuming the appropriate HA configuration options have been selected, which of the following situations would result in VMware HA restarting virtual machines (Choose Two)? A. An ESXi Server in the cluster becomes isolated from the network B. An ESXi Server in the cluster is put into Maintenance Mode C. A guest OS is manually powered off D. A guest OS fails

Answer: A,D Explanation: vSphere Availability Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 11, 12, 23. VMware HA provides high availability for virtual machines by pooling them and the hosts they reside on into a cluster. Hosts in the cluster are monitored and in the event of a failure, the virtual machines on a failed host are restarted on alternate hosts. If you select Enable VM Monitoring, the VM Monitoring service (using VMware Tools) evaluates whether each virtual machine in the cluster is running by checking for regular heartbeats from the VMware Tools process running inside the guest. If no heartbeats are received, this is most likely because the guest operating system has failed or VMware Tools is not being allocated any time to complete tasks. In such a case, the VM Monitoring service determines that the virtual machine has failed and the virtual machine is rebooted to restore service.\ Host network isolation occurs when a host is still running, but it can no longer communicate with other hosts in the cluster. With default settings, if a host stops receiving heartbeats from all other hosts in the cluster for more than 12 seconds, it attempts to ping its isolation addresses. If this also fails, the host declares itself as isolated from the network. When the isolated host's network connection is not restored for 15 seconds or longer, the other hosts in the cluster treat it as failed and attempt to fail over its virtual machines. In a cluster using DRS and VMware HA with admission control turned on, virtual machines might not be evacuated from hosts entering maintenance mode. This is because of the resources reserved to maintain the failover level. You must manually migrate the virtual machines off of the hosts using VMotion.

QUESTION NO: 235 Which of the following are true about the share value for a virtual machine after it has been added to a Resource Pool (Choose Two)? A.

If a previously defined share level (high,medium,low) exists, the %Shares value is maintained D. If a previously defined custom share value exists, the %Shares value is maintained

Answer: A,D Explanation: vSphere Resource Management Guide, ESX 4.0, ESXi 4.0, vCenter Server 4.0, page 38-39 When you move a virtual machine to a new resource pool: If the virtual machine's shares are high, medium, or low, %Shares adjusts to reflect the total number of shares in use in the new resource pool. If the virtual machine has custom shares assigned, the share value is maintained.

QUESTION NO: 404 During installation you manually create a local VMFS volume. What is a possible purpose for this volume? A. storage for service console log files B. decentralized storage for all VMkernel swap activity C. VMkernel swap files for locally configured virtual machines D. service console swap files for over commitment of service console RAM

Answer: B Explanation: Best Practices for vSphere (ESX 4) Service Console Partitions The swap partition is used to supplement RAM if the service console runs out of physical memory. Therefore A is incorrect. In-depth ESX Server service console partitioning and provisioning Because ESX Server's Service Console is based on Red Hat Enterprise Linux, it places its log files in /var/log. Therefore D is incorrect. The Role of Memory in VMware ESX Server 3, page 3. When you power on a virtual machine, a corresponding swap file is created and placed in the same location as the virtual machine configuration file (.vmx file). The virtual machine can power on only when the swap file is available. Therefore C is incorrect. Mastering Vmware vSphere 4, page 219. Local storage is still used by default in vSphere ESX 4 installations as the ESX userworld swap (think of this as the ESX host swap and temp use). Therefore B is correct.

ESX Server does not support datastore on CIFS. C. ESX Server requires gigabit Ethernet adapter in order for CIFS to be used as datastore. D. ESX Server must be on the same LAN as the CIFS server.

Answer: B Explanation: ESX Configuration Guide ESX 4.0 vCenter Server 4.0, page 77. Depending on the type of storage you use, datastores can be backed by the following file system formats: · Virtual Machine File System (VMFS) - High-performance file system optimized for storing virtual machines. Your host can deploy a VMFS datastore on any SCSI-based local or networked storage device, including Fibre Channel and iSCSI SAN equipment. As an alternative to using the VMFS datastore, your virtual machine can have direct access to raw devices and use a mapping file (RDM) as a proxy. Network File System (NFS) - File system on a NAS storage device. ESX supports NFS version 3 over TCP/IP. The host can access a designated NFS volume located on an NFS server, mount the volume, and use it for any storage needs.

QUESTION NO: 104 An ESX Host gains exclusive access to Virtual Machines created on NFS datastores using which of the following mechanisms? A. SCSI Reservations B. a special .lck-XXX lock file C. NFS File Locking Protocol D. Distributed File Locking

Answer: B Explanation: ESX ESX Configuration Guide ESX 4.0 vCenter Server 4.0 When your host accesses a virtual machine disk file on an NFS-based datastore, a .lck-XXX lock file is generated in the same directory where the disk file resides to prevent other hosts from accessing this virtual disk file. Do not remove the .lck-XXX lock file, because without it, the running virtual machine cannot access its virtual disk file.

Answer: B Explanation: ESX and vCenter Server Installation Guide, ESX 4.0, vCenter Server 4.0, page 108. 'License keys have a certain amount of capacity. Capacity is based on the number of processors in the host or the number of instances of the software asset. Dual-core and quad-core processors, such as Intel processors that combine two or four independent CPUs on a single chip, count as one processor.' Therefore since there will be 4 CPUs in total, 4 licenses are required.

QUESTION NO: 458 You have decided to install vCenter on an existing Windows Server running an application that is accessed through standard HTTP and HTTPS connections, ports 80 and 443. What will you need to do in order to successfully deploy vCenter? A. No additional action is required B. You must specify alternate vCenter Web Service ports during installation and manually specify the alternate ports when connecting with the vSphere Client. C. You must move the application to another server but keep IIS installed and running on ports 80 and 443 for use with SDK clients. D. You must change the vCenter Web Service port to 905 if SDK clients will be used.

Answer: B Explanation: ESX and vCenter Server Installation Guide, ESX 4.0, vCenter Server 4.0, page 19 and 91. Install vCenter Server - Procedure. 12. Enter the port numbers that you want to use or accept the default port numbers and click Next. vCenter Server requires port 80 for direct HTTP connections. Port 80 redirects requests to HTTPS port 443. This is useful if you accidentally use http://server instead of https://server. The vCenter Server system also uses port 443 to listen for data transfer from the vSphere Web Access Client and other SDK clients. If you use another port number for HTTPS, you must use <ip-address>:<port> when you log in to the vCenter Server system.

QUESTION NO: 87 An administrator is configuring an ESX Host with 2 Fibre Channel HBAs. The attached FC Storage Array has two active Storage Processor ports. No zoning is configured. Using Round Robin multipathing, how many paths are used to send data to a VMFS Datastore at any given time? A. 2 B. 1 C. 3 D. 4

Answer: B Explanation: Fibre Channel SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 25. Round Robin (RR) Uses a path selection algorithm that rotates through all available paths enabling load balancing across the paths. Round-Robin Load Balancing VMware ESX Server 3.5, VMware ESX Server 3i version 3.5, VMware VirtualCenter 2.5, page 1 When one path from the ESX Server host to the SAN becomes unavailable, the host switches to another path. ESX Server hosts can also use multipathing for load balancing. When to switch - Specify that the ESX Server host should attempt a path switch after a specified number of I/O blocks have been issued on a path or after a specified number of read or write commands have been issued on a path. If another path exists that meets the specified path policy for the target, the active path to the target is switched to the new path. Since the active path is switched to a new path, it can be assumed that only a single path is ever used at any given time, (B above).

QUESTION NO: 436 Click the Exhibit button. The exhibit shows paths of a SAN LUN. What is the LUN number? A. 1 B. 0 C. 2 D. 3

Answer: B Explanation: Fibre Channel SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 53 Understanding Storage Device Naming Runtime Name The name of the path to the device. The runtime name is created by the host. The name is not a reliable identifier for the device, and is not persistent. The runtime name has the following format: vmhba#:C#:T#:L#, where vmhba# is the name of the storage adapter. The name refers to the physical adapter on the host, not to the SCSI controller used by the virtual machines. C# is the storage channel number. T# is the target number. Target numbering is decided by the host and might change if there is a change in the mappings of targets visible to the host. Targets that are shared by different hosts might not have the same target number. L# is the LUN number that shows the position of the LUN within the target. The LUN number is provided by the storage system. If a target has only one LUN, the LUN number is always zero (0). For example, vmhba1:C0:T3:L1 represents LUN1 on target 3 accessed through the storage adapter vmhba1 and channel 0. Therefore vmhba2:2:0, vmhba2:3:0, vmhba3:0:0 and vmhba3:1:0 all have a LUN number of 0.

QUESTION NO: 84 To prevent non-ESX Servers from seeing VMFS datastores, where should LUN masking be configured? A. on the non-ESX Hosts B. on the SAN Storage Device C. on the Fibre Channel Switch D. on the ESX Host

QUESTION NO: 282 During peak operating hours, an Administrator finds that a business critical application is not performing as well as during normal hours. Which of the following memory management methods could be used to guarantee the application performs well at all times? A. Set the Share level to High for the virtual machine running the application and set all other virtual machines to Low B. Set a Reservation equal to the Peak Memory utilization of the virtual machine running the application C. Set the Share level to High for the virtual machine running the application D. Set a Reservation equal to the Average Memory utilization of the virtual machine running the application

Answer: B Explanation: Memory Provisioning Recommendations for VMware Infrastructure 3 Operational Best Practices page 8. Memory Reservations, Limits, and Shares Memory Reservations are an ESX Server memory management technique used to control how memory is allocated from an either an explicit or implicit resource pool by the VMkernel to a virtual machine or group of virtual machines. Reservations consist of two settings - a reservation, or guaranteed amount of physical memory that will always be available to the virtual machine(s), and a limit, which is the absolute maximum physical memory a virtual machine or group of virtual machines can consume on the host During peak operating hours, by definition more systems and more resources including memory, will be being consumed. Therefore memory reservation is required. By setting a reservation equal to the peak memory utilization, this will guarantee the application receives all memory it requires.

QUESTION NO: 513 Which memory allocation technique allows physical memory to be reclaimed from virtual machine A and redistributed to virtual machine B, possibly forcing virtual machine A to swap internally? A. Transparent Page Sharing B. Memory Balloon Driver C. VMkernel Swap D. RAM Overcommit

Answer: B Explanation: Memory Provisioning Recommendations for VMware Infrastructure 3 Operational Best Practices, page 7 Memory Ballooning Memory ballooning is handled through a driver (vmmemctl.sys) that is installed as part of the VMware Tools. This driver is loaded in the guest OS to interact with the VMkernel and is leveraged to reclaim memory pages when ESX memory resources are in demand and available physical pages cannot meet requirements. When memory demands rise on the ESX host, the VMkernel will instruct the balloon driver to "inflate" and consume memory in the running guest OS, forcing the guest operating system to leverage its own native memory management techniques to handle changing conditions.

QUESTION NO: 300 Using VMware Data Recovery, backing up a VM created on a ESX3.5 host will take longer than a VM created on a ESX4 host? A. False B. True

Answer: B Explanation: VMware Data Recovery Administration Guide Data Recovery 1.1, page 8. For virtual machines created in vSphere 4.0, the Data Recovery appliance creates a quiesced snapshot of the virtual machine during the backup. The backups use the changed block tracking functionality on the ESX hosts. For each virtual disk being backed up, it checks for a prior backup of the virtual disk. It uses the change-tracking functionality on ESX hosts to obtain the changes since the last backup. The deduplicated store creates a virtual full backup based on the last backup image and applies the changes to it. NOTE These optimizations do not apply to virtual machines created with VMware products prior to vSphere 4.0. For example, change tokens are not used with virtual machines created with Virtual Infrastructure 3.5 or earlier. As a result, virtual machines created with earlier VMware versions take longer to back up

QUESTION NO: 441 Where is LUN masking configured? (Choose two.) A. on the Fibre Switch B. on the host C. on the storage processor D. on the Ethernet switch E. on the firewall

Answer: B,C Explanation: LUN Masking in a SAN There are three places where LUN Masking can be implemented. The first is in the storage, the second is in the servers [the host], and the third is either in a device through which all of the I/O passes or the SAN itself, [the switch]. Each of these has its benefits. In practice, LUN Masking at a customer site is implemented in multiple ways reflecting the different methods used by each vendor. To implement LUN Masking in the switch would require that a time consuming table look-up be performed that is not currently possible within Implementing LUN Masking due to memory constraints on the fibre channel switch ASIC. This means that all of the data would need to be staged to a central cache before being forwarded on. This is simply not possible with today's technology without increasing the latency by a factor of 10 to 100 times. Therefore the only practical place to perform LUN masking is on the host or on the storage processor, (B & C).

QUESTION NO: 277 A request has been made to the SAN Administrator to provision a new LUN. A LUN (LUN 6) is created and the SAN administrator presents the LUN to the ESX Server using the storage array SAN Management software. After a Rescan operation on the ABC.com ESX Server, the LUN does not show up. Other LUNs from the same storage array are visible. Which of the following could be the cause (Choose Two)? A. The HBA on the active path is shared with the service console B. The LUN was not presented to the correct ESX Server C. LUN masking on a range of LUNS is enabled on the ESX Server, causing LUN 6 to be ignored D. Zoning is not set up correctly

Answer: B,C Explanation: Using Storage Area Networks with ESX Server. Disk arrays carve the storage RAID set into logical units (LUNs) that are presented to the server in a manner similar to an independent single disk. Typically, LUNs are few in number, relatively large, and fixed in size. Therefore it is possible that the LUN was not presented to the correct ESX server, (B above). For administrative or security purposes, you can use LUN masking to prevent the server from seeing LUNs that it doesn't need to access. Therefore it is possible an incorrect mask has been set up, (C above).

QUESTION NO: 74 Suppose you have 10000 Virtual Machines across 2 Datacenters, with approximately 5000 Virtual Machines in each Datacenter.

QUESTION NO: 99 Using Hardware iSCSI Initiators with ESX/ESXi hosts allows which of the following tasks to be offloaded from the VMkernel? A. Issuing SCSI commands to the virtual disk B. Encapsulation of I/O requests into iSCSI Protocol Data Units (PDUs) C. Encapsulation of iSCSI PDUs into TCP/IP packets D. Mapping requests for blocks on the virtual disk to blocks on the appropriate physical device

Answer: B,C Explanation: iSCSI From Wikipedia, the free encyclopedia An initiator functions as an iSCSI client. An initiator typically serves the same purpose to a computer as a SCSI bus adapter would, except that instead of physically cabling SCSI devices (like hard drives and tape changers), an iSCSI initiator sends SCSI commands over an IP network. An initiator falls into two broad types: Software initiator A software initiator uses code to implement iSCSI. Typically, this happens in a kernel-resident device driver that uses the existing network card (NIC) and network stack to emulate SCSI devices for a computer by speaking the iSCSI protocol. Software initiators are available for most mainstream operating systems, and this type is the most common mode of deploying iSCSI on computers. Hardware initiator A hardware initiator uses dedicated hardware, typically in combination with software (firmware) running on that hardware, to implement iSCSI. A hardware initiator mitigates the overhead of iSCSI [B above] and TCP [A above] processing and Ethernet interrupts, and therefore may improve the performance of servers that use iSCSI.

QUESTION NO: 215 Which of the following are requirements for a fully functional VMware HA cluster (Choose Two)? A. compatible CPUs in each host B. sufficient capacity to support at least one host failover C. access to shared storage from all hosts D. a minimum of 2 Service Console ports

Answer: B,C Explanation: vSphere Availability Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, Page 11. VMware HA provides high availability for virtual machines by pooling them and the hosts they reside on into a cluster. Hosts in the cluster are monitored and in the event of a failure, the virtual machines on a failed host are restarted on alternate hosts. Therefore there should be sufficient capacity to support at least one host failover, (C) vSphere Availability Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, Page 20. All virtual machines and their configuration files must reside on shared storage. So that you can power on the virtual machines using different hosts in the cluster, the hosts must be configured to access that shared storage, (B).

QUESTION NO: 81 In vSphere 4, when multiple Multipathing Plugins (MPPs) exist, the Pluggable Storage Architecture (PSA) performs which of the following three tasks (Choose Three)? A. Association of physical paths with logical devices B. I/O queuing to the logical devices C. Physical path discovery and removal D. Management tasks such as abort or reset of logical devices E. I/O queuing to the physical storage HBAs

Answer: B,C,E Explanation: What is Pluggable Storage Architecture (PSA) and Native Multipathing (NMP)? Pluggable Storage Architecture (PSA) PSA is a collection of VMkernel APIs that allow third party hardware vendors to insert code directly into the ESX storage I/O path. This allows 3rd party software developers to design their own load balancing techniques and failover mechanisms for particular storage array. The PSA coordinates the operation of the NMP and any additional 3rd party MPP. Native Multipathing Plugin (NMP) VMware provides a generic Multipathing Plugin (MPP), called Native Multipathing Plugin (NMP). What does NMP do? · Manages physical path claiming and unclaiming. · Registers and de-registers logical devices. · Associates physical paths with logical devices. · Processes I/O requests to logical devices: o Selects an optimal physical path for the request (load balance) [B above] o Performs actions necessary to handle failures and request retries. · Supports management tasks such as abort or reset of logical devices.[C above] Since the NMP provides B and C, the PSA must perform A, D and E

QUESTION NO: 448 Which of the following are requirements for a VMware HA cluster? (Choose Two.) A. a private Ethernet network for all hosts B. access to shared storage from all hosts C. identical type and quantity of CPUs in each host D. access to the virtual machine networks from all hosts

Answer: B,D Explanation: Clusters Enabled for HA For clusters enabled for HA, all virtual machines and their configuration files must reside on shared storage (typically a SAN), because you must be able to power on the virtual machine on any host in the cluster. This also means that the hosts must be configured to have access to the same virtual machine network and to other resources. Each host in an HA cluster must be able to resolve the host name and IP address of all other hosts in the cluster. To achieve this, you can either set up DNS on each host (preferred) or fill in the /etc/hosts entries manually (error prone and discouraged).

QUESTION NO: 209 Which of the following is true regarding a mixed DRS cluster with Intel and AMD based ESX Hosts (Choose Two)? A. VMware DRS can load balance running virtual machines using all hosts in the cluster B. Storage VMotion will function with any host in the cluster C. VMotion can move live virtual machines between any two hosts in the cluster D. VMware HA will failover virtual machines to any host in the cluster

Answer: B,D Explanation: DRS Performance and Best Practices VMware® Infrastructure 3 If you are configuring a DRS cluster with heterogeneous hosts, be sure to consider the following factors: VMotion hardware compatibility—Virtual machines cannot use VMotion to migrate across different CPU types (from Intel to AMD or vice versa VMware DRS and VMotion: Improve workload balance, prevent problems Simply put, DRS ensures that your resource requirements are enforced. You start with a number of VMware host systems, shared storage, same network presence, and resource pools that you define. From there, DRS will balance the workload across the resources you presented to the cluster.

QUESTION NO: 83 What are two functions of zoning in Fibre Channel Switches (Choose Two)? A. Reduces the number of targets and LUNs presented by a Fibre Channel Storage Array B. Prevents non-ESX Hosts from possibly destroying VMFS data C. Controls and isolates LUNs on a Fibre Channel Storage Array D. Restrict connections on a storage array to ESX Hosts that utilize the array

Answer: B,D Explanation: Fibre Channel SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 53, page 15. To restrict server access to storage arrays not allocated to that server, the SAN uses zoning. [A above] Typically, zones are created for each group of servers that access a shared group of storage devices and LUNs. Zones define which HBAs can connect to which SPs. Devices outside a zone are not visible to the devices inside the zone. Since devices outside a zone are not visible to the devices inside the zone it would rrevents non-ESX Hosts from accessing and possibly destroying VMFS data. [B above]

Perl must be installed in the Linux guest OS C. The Linux Open Source tools must be added to the vCenter Server D. Microsoft Sysprep tools must be placed on the vCenter Server

Answer: B,D Explanation: If you plan to customize a Windows guest operating system, you must first install the Microsoft Sysprep tools, . Perl must be installed in the Linux guest OS. Incorrect answer: If you plan to customize a Linux guest operating system (this is not required in this scenario), you must first install the VMware Open Source components on your VirtualCenter management server machine.

QUESTION NO: 113 Raw Device Mapping using Physical Compatibility Mode is supported with which of the following vSphere features (Choose Two)? A. Cloning B. VMotion C. Virtual Machine Snapshots D. High Availability (HA)

Answer: B,D Explanation: Mastering VMware vSphere 4, page 270-1. Physical compatibility mode (pRDM) The inability to take a native Vmware snapshot of a pRDM also means that features that depend on Vmware snapshots (the vStorage API's for Data Protection, Vmware Data Recovery, and Storage vMotion) don't work with pRDMs. VMware -Raw Device Mapping (RDM) With Physical compatibility mode you VM can access LUN directly. This is generally used from the application inside VM wants to directly access LUN. However using physical compatibility mode you lose the option to clone a VM, make it a template and migration when it involves moving disks.

QUESTION NO: 269 An Administrator has determined that storage performance to a group of virtual machines is reduced during peak activity. The virtual machines are all located in a VMFS datastore called Production I on an Active/Active storage array. The ESX Host is currently configured with an MRU multipathing policy. Which of the following achons could be taken to improve the storage performance of these virtual machines (Choose Two)? A. Add additional physical storage and add an extent to the VMFS datastore called Production1 B. Change the storage multipathing policy to Fixed C. Change the storage multipathing policy to Round-Robin D. Add additional physical storage, create a new VMFS datastore called Production2 on the new storage, then migrate a portion of the virtual machines from Production 1 to Production 2

Answer: B,D Explanation: Storage performance refers to how to how efficiently, (typically how quickly), storage operates. By adding a new datastore, and migrate a portion of the virtual machines from Production1 to Production2 is likely to reduce the load on the original datastore, and hence improve responsiveness, and hence performance. These pathing policies can be used with VMware ESX 4.x: Most Recently Used (MRU) — Selects the first working path, discovered at system boot time. If this path becomes unavailable, the ESX host switches to an alternative path and continues to use the new path while it is available. This is the default policy for Logical Unit Numbers (LUNs) presented from an Active/Passive array. ESX does not return to the previous path when if, or when, it returns; it remains on the working path until it, for any reason, fails. Note: The preferred flag, while sometimes visible, is not applicable to the MRU pathing policy and can be disregarded. Fixed (Fixed) — Uses the designated preferred path flag, if it has been configured. Otherwise, it uses the first working path discovered at system boot time. If the ESX host cannot use the preferred path or it becomes unavailable, ESX selects an alternative available path. The ESX host automatically returns to the previouslydefined preferred path as soon as it becomes available again. This is the default policy for LUNs presented from an Active/Active storage array. Round Robin (RR) — Uses an automatic path selection rotating through all available paths, enabling the distribution of load across the configured paths. For Active/Passive storage arrays, only the paths to the active controller will used in the Round Robin policy. For Active/Active storage arrays, all paths will used in the Round Robin policy. Note: This policy is not currently supported for Logical Units that are part of a Microsoft Cluster Service (MSCS) virtual machine. Fixed path with Array Preference — The VMW_PSP_FIXED_AP policy was introduced in ESX 4.1. It works for both Active/Active and Active/Passive storage arrays that support ALUA. This policy queries the storage array for the preferred path based on the arrays preference. If no preferred path is specified by the user, the storage array selects the preferred path based on specific criteria. Notes: These pathing policies apply to VMware's Native Multipathing (NMP) Path Selection Plugins (PSP). Third party PSPs have their own restrictions. Switching to Round Robin from MRU or Fixed is safe and supported for all arrays unless otherwise explicitly documented. Warning: VMware does not recommend changing the LUN policy from Fixed to MRU, as the automatic selection of the pathing policy is based on the array that has been detected by the NMP PSP.

QUESTION NO: 204 Which of the following would prevent the application of a Host Profile to an ESX Host (Choose Two)? A. The host is an ESXi Host B. The host has not been placed into Maintenance Mode C. The host has multiple profiles attached D. The host is an ESX 3.5 Host

Answer: B,D Explanation: Vmware Knowledge Base KB 1010732 Applying a Host Profile to a host or cluster Note: The host must be in maintenance mode before applying it to a profile. The screenshot below shows the error obtained whilst trying apply a Host Profile to a system not in maintenance mode. Host profiles from ESX 3.5 U3 to ESX 4.0 U1 As others have stated, you can only use host profiles with ESX 4 hosts. So you can create a profile from an existing ESX 4 host and then apply it to other existing ESX 4 hosts

Answer: B,D Explanation: vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0 , page216 Clone a Role You can make a copy of an existing role, rename it, and later edit it. When you make a copy, the new role is not applied to the same users or groups and objects

QUESTION NO: 288 A user wants to receive an email notification when the virtual machine CPU usage enters a warning state, and again when the condition has been resolved. Which two state changes must be selected to receive the appropriate notifications (Choose Two)? A. red-green state change B. yellow-green state change C. yellow-red state change D. green-yellow state change

Answer: B,D Explanation: vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 235. VMware uses colors to denote alarm severity: Normal - green Warning - yellow Alert - red You can set alarms to trigger when the state changes from green to yellow, yellow to red, red to yellow, and yellow to green. When the virtual machine CPU usage enters a warning state, it will change from Normal (green) to Warning (yellow). When the condition has been resolved it will change from Warning (yellow) to Normal (green).

QUESTION NO: 511 Which of the following statements best describe network traffic shaping (Choose Two.) A. Network traffic shaping can limit inbound peak bandwidth B. Network traffic shaping can limit outbound peak bandwidth C. Network traffic shaping can limit inbound average bandwidth D. Network traffic shaping can limit outbound average bandwidth

Answer: B,D Explanation: vSphere Help ESX/ESXi allows you to shape outbound traffic on virtual switches. The traffic shaper restricts the network bandwidth available to any port, but may also be configured to temporarily allow "bursts" of traffic to flow through a port at higher speeds. A traffic shaping policy is defined by three characteristics: average bandwidth, peak bandwidth, and burst size. Average Bandwidth - Establishes the number of bits per second to allow across a port, averaged over time—the allowed average load. Burst Size - The maximum number of bytes to allow in a burst. If this parameter is set, a port may gain a burst bonus when it doesn't use all its allocated bandwidth. Whenever the port needs more bandwidth than specified by Average Bandwidth, it may be allowed to temporarily transmit data at a higher speed if a burst bonus is available. This parameter tops the number of bytes that may be accumulated in the burst bonus and thus transferred at a higher speed. Peak Bandwidth - The maximum number of bits per second to allow across a port when it is sending a burst of traffic. This tops the bandwidth used by a port whenever it is using its burst bonus. This parameter can never be smaller than the average bandwidth.

QUESTION NO: 447 What are three requirements for a VMware HA cluster? (Choose three.) A. Private Gigabit Ethernet network for all hosts B. access to shared storage from all hosts C. identical type and quantity of CPUs in each host D. access to the virtual machine networks from all hosts E. name resolution between all hosts

Answer: B,D,E Explanation: Clusters Enabled for HA For clusters enabled for HA, all virtual machines and their configuration files must reside on shared storage (typically a SAN), because you must be able to power on the virtual machine on any host in the cluster. This also means that the hosts must be configured to have access to the same virtual machine network and to other resources. Each host in an HA cluster must be able to resolve the host name and IP address of all other hosts in the cluster. To achieve this, you can either set up DNS on each host (preferred) or fill in the /etc/hosts entries manually (error prone and discouraged).

QUESTION NO: 130 Which of the following are prerequisites for installing vCenter Server (Choose Three)? A. The system vCenter is installed on can be in a workgroup or a domain B. The system vCenter is installed on must belong to a domain C. The system vCenter is installed on must be a physical server D. The system vCenter is installed on can be a virtual machine or physical server E. The system vCenter is installed on must have a Static IP address or be registered with DNS if using DHCP

Answer: B,D,E Explanation: ESX and vCenter Server Installation Guide, ESX 4.0, vCenter Server 4.0 Page 16, 83-84. The vCenter Server system is a physical machine or virtual machine with access to a supported database. [D above] The system that you use for your vCenter Server installation must belong to a domain rather than a workgroup. If assigned to a workgroup, the vCenter Server system is not able to discover all domains and systems available on the network when using such features as vCenter Guided Consolidation Service. [B above] This paragraph is highly confusing, as it contradicts itself. However, in fact vCenter Server can be installed to a system residing in a workgroup, as shown below. vCenter Server, like any other network server, should be installed on a machine with a fixed IP address and well-known DNS name, so that clients can reliably access the service. If you use DHCP instead of a static IP address for vCenter Server, make sure that the vCenter Server computer name is updated in the domain name service (DNS). [E above]

QUESTION NO: 423 Which two CPU characteristics must be identical for a successful migration with VMotion between ESX Servers? (Choose two.) A. CPU clock speed B. CPU stepping C. CPU cache size D. SSE3 support E. CPU vendor

Answer: B,E Explanation: vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 47. VMotion transfers the running architectural state of a virtual machine between underlying ESX/ESXi hosts. CPU vendor: VMotion compatibility means that the processors of the destination host must be able to resume execution using the equivalent instructions where the processors of the source host were suspended. Processor clock speeds and cache sizes might vary, but processors must come from the same vendor class (Intel versus AMD) and same processor family to be compatible for migration with VMotion. CPU: CPU stepping Processor families such as Xeon MP and Opteron are defined by the processor vendors. You can distinguish different processor versions within the same family by comparing the processors' model, stepping level, and extended features. In some cases, processor vendors have introduced significant architectural changes within the same processor family (such as 64-bit extensions and SSE3). VMware identifies these exceptions if it cannot guarantee successful migration with VMotion.

QUESTION NO: 568 When securing an ESX 4.x host using the built-in firewall,the Startup Policy conterols how services start based on the state of the ports they usE. Which of the following are valid startuo policies? A. Start and stop with host B. Start and stop automatically C. Start automatically if any ports are open, and stop when all ports are closed D. Start automatically, opening any closed ports used by this service

Answer: C Explanation: Automating Service Behavior Based on Firewall Settings * Start automatically if any ports are open, and stop when all ports are closed - The default setting for these services that VMware recommends. If any port is open, the client attempts to contact the network resources pertinent to the service in question. If some ports are open, but the port for a particular service is closed, the attempt fails, but there is little drawback to such a case. If and when the applicable outgoing port is opened, the service begins completing its tasks. * Start and stop with host- The service starts shortly after the host starts and closes shortly before the host shuts down. Much like Start automatically if any ports are open, and stop when all ports are closed, this option means that the service regularly attempts to complete its tasks, such as contacting the specified NTP server. If the port was closed but is subsequently opened, the client begins completing its tasks shortly thereafter. * Start and stop manually - The host preserves the user-determined service settings, regardless of whether ports are open or not. When a user starts the NTP service, that service is kept running as long as the host is powered on. If the service is started and the host is powered off, the service is stopped as part of the shutdown process, but as soon as the host is powered on, the service is started again, preserving the userdetermined state.

QUESTION NO: 283 Users are complaining that a Windows application server Virtual Machine configured with 1GB RAM is not performing satisfactorily. An administrator opens the Performance Tab for the guest virtual machine and adds the counter for Memory Ballooned in MB. The Performance Chart displays a value of 240. Which of the following actions should be taken? A. Adjust the Mem.CtlMaxPercent to read 75. B. Add more memory to the Virtual Machine. C. Migrate the Virtual Machine to another host. D. Monitor memory ballooning from the ESX host Performance Tab

Answer: C Explanation: Memory Provisioning Recommendations for VMware Infrastructure 3 Operational Best Practices, page 11. Memory Balloon - This counter reflects the total amount of memory the VMkernel is effectively "borrowing" from virtual machines via the VMTools balloon driver running inside the guest OS. Balloon driver activity indicates over-commitment of ESX host memory. By default, the VMkernel may balloon up to 65% of a virtual machine's configure RAM. Users are complaining that a Windows application server is not performing satisfactorily. The Memory Balloon counter indicates that memory is being borrowed by the Vmkernel from the virtual machine, indicating that the host has insufficient memory to service requirements from all virtual machines. Therefore either more memory should be added to the host or the guest should be moved to a system with more free memory.

QUESTION NO: 392 Which is a valid reason NOT to set affinity on a single virtual machine (VM)? A. Affinity settings are ignored as part of a VMotion B. Affinity can only be set on hyperthreaded systems. C. A VM with affinity might not receive 100 percent of the CPU. D. Setting affinity will monopolize a CPU making it unusable for other VMs on the server.

Answer: C Explanation: vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 19, 20. By specifying a CPU affinity setting for each virtual machine, you can restrict the assignment of virtual machines to a subset of the available processors in multiprocessor systems. By using this feature, you can assign each virtual machine to processors in the specified affinity set. In this context, the term CPU refers to a logical processor on a hyperthreaded system, but refers to a core on a non-hyperthreaded system. The CPU affinity setting for a virtual machine applies not only to all of the virtual CPUs associated with the virtual machine, but also to all other threads (also known as worlds) associated with the virtual machine. Such virtual machine threads perform processing required for emulating mouse, keyboard, screen, CD-ROM and miscellaneous legacy devices. Consider your resource management needs before you enable CPU affinity on hosts using hyperthreading. For example, if you bind a high priority virtual machine to CPU 0 and another high priority virtual machine to CPU 1, the two virtual machines have to share the same physical core. In this case, it can be impossible to meet the resource demands of these virtual machines. Ensure that any custom affinity settings make sense for a hyperthreaded system.

QUESTION NO: 231 A resource pool exists with a memory reservation of 14GB. The pool has 5 single-processor virtual machines and 2 dual-processor virtual machines. Each of these VMs has a memory reservation of 2GB. When an attempt is made to power on the seventh Virtual Machine in the resource pool, a single-processor VM with a 2GB memory reservation, a warning states there is insufficient memory resources to power on the VM. The reason for this warning is? VMware VCP-410: Practice Exam "Pass Any Exam. Any Time." - www.actualtests.com 142 A. The VMkernel device drivers are consuming memory B. Service Console memory has not been increased to accommodate the virtual machine workload C. Overhead memory for the VMs is consuming memory in the resource pool D. Memory reservations for the VMs are consuming memory in the pool

Answer: C Explanation: vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 28 Virtual machines incur overhead memory. You should be aware of the amount of this overhead. Table 3-2 lists the overhead memory (in MB) for each number of VCPUs. Table 3-2. Overhead Memory on Virtual Machines Memory (MB) 1 VCPU 2 VCPUs 2048 137.81 198.20 There are currently 6 virtual machines powered up, consuming 6 x 2GB reservations = 12GB 4 single processor machines, = 4 x 137.81 MB = 552MB 2 dual processor machines, = 2 x 198.20 MB = 396 MB Total memory consumed is 12.92 GB, so total memory available = 1.08GB When an attempt is made to power on the seventh Virtual Machine in the resource pool, an additional 2 GB + 137 MB is required. Since this is not available, the machine cannot start.

QUESTION NO: 497 Which statement is true about transparent page sharing? A. It only works with Windows. B. It is the process of collecting unused memory from the guest OS and returning it to the VMkernel. C. It is the method of eliminating duplicate pages of memory allocated to multiple virtual machines. D. It only works with supported guest OS.

Answer: C Explanation: vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 74 For example, several virtual machines might be running instances of the same guest operating system, have the same applications or components loaded, or contain common data. In such cases, ESX/ESXi systems use a proprietary transparent page-sharing technique to securely eliminate redundant copies of memory pages.

QUESTION NO: 21 In order to upgrade to vSphere 4, an ESX host must have a /boot partition of at least? A. 150 MB B. 200 MB C. 100 MB D. 50 MB

Answer: C Explanation: vSphere Upgrade Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0 vSphere Client 4.0 Page 73 Direct, in-place upgrade from ESX 2.5.5 to ESX 4.0 is not supported, even if you upgrade to ESX 3.x as an intermediary step. The default ESX 2.5.5 installation creates a /boot partition that is too small to enable upgrades to ESX 4.0. As an exception, if you have a non-default ESX 2.5.5 installation on which at least 100MB of space is available on the /boot partition, you can upgrade ESX 2.5.5 to ESX 3.x and then to ESX 4.0.

QUESTION NO: 17 Before you upgrade an ESX host? A. back up /proc, /mnt, /tmp, custom scripts and all VMFS datastores B. back up /home, /etc/init.d and /boot C. back up /etc/passwd, /etc/groups, /etc/shadow, /etc/gshadow, custom scripts and local VMFS D. back up /var/logs, /usr, /bin and the dmesg output

Answer: C Explanation: vSphere Upgrade Guide ESX 4.0, ESXi 4.0, vCenter Server 4.0, vSphere Client 4.0, page 71 'Before you upgrade an ESX host, back up the local VMFS file system. This ensures that you will not lose data during the upgrade. Procedure · Back up the files in the /etc/passwd, /etc/groups, /etc/shadow, and /etc/gshadow directories.

QUESTION NO: 10 Once vCenter 4.x has been installed, a License Server is required in which of the following instances? A. A License Server is always required B. To support ESXi 4.x Hosts C. To support ESX 3.5 Hosts D. A License Server is no longer required

Answer: C Explanation: vSphere uses a new centralized license reporting and management structure, which means that if all ESX hosts are upgraded to version 4, no license server or host license file is needed. ESX 3.5 hosts still require access to a license server, which can be used by the vSphere Virtual Center by configuring the License Server option under Administration—Server Settings.

QUESTION NO: 182 Windows Virtual machine use a page file and Linux Virtual Machine use a swap partition for virtual memory. When determining the appropriate size for these, which of the following files would be affected? A. the .vswp file B. the .vmdk file C. the -flat.vmdk file D. the Service Console swap partition

Answer: C Explanation: Explanation/Reference The -flat.vmdk file. This is the default large virtual disk data file that is created when you add a virtual hard drive to your VM that is not an RDM. When using thick disks, this file will be approximately the same size as what you specify when you create your virtual hard drive. Since both the Windows page file and Linux swap partition are located on the virtual disk, the -flat.vmdk file will be affected.

QUESTION NO: 159 An administrator wants to use standard images for virtual machine deployment. What are two benefits that can be achieved by creating these images as templates (Choose Two)? A. easier to upgrade and manage multiple VMs B. templates deploy faster than cloning C. base images cannot be directly modified D. less disk space used for base images

Answer: C,D Explanation: VirtualCenter 2 Templates Usage and Best Practices, page 3. Overview of VirtualCenter 2 Templates Templates have been redesigned to fit into the new VMware Infrastructure inventory model and have been updated to address the need to keep virtual machines updated with the most recent operating systems and application patches. Instead of saving virtual machine templates in a completely separate inventory, VirtualCenter 2 stores templates into the main inventory with other virtual machines. However, templates are identified by a different icon and by the ability to prevent them from powering on. As such, templates can now be: • Viewed from the "Virtual Machines and Templates" or the "Hosts and Clusters" inventory views. • Quickly converted back and forth between virtual machines that can be powered on and receive updates and templates that cannot powered on, but can be used as the source images from which to deploy new virtual machines. • Stored in monolithic (runnable) virtual disk format for quick template-t- virtual machine conversions or stored in sparse (non-runnable) virtual disk format to conserve storage space.

Fusion uses the same virtual machine format as Workstation 6 and Player 2. Generally speaking, you should be able to move a virtual machine between these programs.

QUESTION NO: 500 When setting up the Iscsi software initiator on an ESX Server, which virtual switch port types are required? (Choose Two.) A. Iscsi B. Virtual machine C. Service Console D. VMkernel

Answer: C,D Explanation: With the software-based iSCSI implementation, you can use standard network adapters to connect your ESX/ ESXi host to a remote iSCSI target on the IP network. The software iSCSI initiator that is built into ESX/ESXi facilitates this connection by communicating with the network adapter through the network stack. Before you configure the software iSCSI initiator, you must perform the following tasks: 1 Create a VMkernel port for physical network adapters. [D above] 2 Enable the software iSCSI initiator. 3 If you use multiple network adapters, activate multipathing on your host using the port binding technique. 4 If needed, enable Jumbo Frames. Jumbo Frames must be enabled for each vSwitch through the vSphere CLI. Also, if you use an ESX host, you must create a VMkernel network interface enabled with Jumbo Frames. Networking Configuration for Software iSCSI Storage Server Configuration Guide : Networking Scenarios and Troubleshooting : Networking Configuration for Software iSCSI Storage The storage you configure for an ESX Server host might include one or more storage area networks (SANs) that use iSCSI, which is a means of accessing SCSI devices and exchanging data records using TCP/IP protocol over a network port rather than through a direct connection to a SCSI device. In iSCSI transactions, blocks of raw SCSI data are encapsulated in iSCSI records and transmitted to the requesting device or user. Before you can configure iSCSI storage, you must create a VMkernel port to handle iSCSI networking and a service console connection to the iSCSI network. [C and D above].

QUESTION NO: 501 Which of the following statements are true about software iSCSI? (Choose Two) A. It requires a dedicated NIC B. It is enabled by def ault. C. CHAP authentication can be configured. D. SendTargets can be configured.

Answer: C,D Explanation: iSCSI SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 35, 37. Set up target discovery addresses so that the iSCSI initiator can determine which storage resource on the network is available for access. The ESX/ESXi system supports these discovery methods: Dynamic Discovery Also known as Send Targets discovery. Each time the initiator contacts a specified iSCSI server, the initiator sends the Send Targets request to the server. The server responds by supplying a list of available targets to the initiator. The names and IP addresses of these targets appear on the Static Discovery tab. If you remove a static target added by dynamic discovery, the target might be returned to the list the next time a rescan happens, the HBA is reset, or the host is rebooted. Static Discovery The initiator does not have to perform any discovery. The initiator has a list of targets it can contact and uses their IP addresses and target names to communicate with them. Because the IP networks that the iSCSI technology uses to connect to remote targets do not protect the data they transport, you must ensure security of the connection. iSCSI requires that all devices on the network implement Challenge Handshake Authentication Protocol (CHAP), which verifies the legitimacy of initiators that access targets on the network. CHAP uses a three-way handshake algorithm to verify the identity of your host and, if applicable, of the iSCSI target when the host and target establish a connection. The verification is based on a predefined private value, or CHAP secret, that the initiator and target share. ESX/ESXi supports CHAP authentication at the adapter level. In this case, all targets receive the same CHAP name and secret from the iSCSI initiator. For software iSCSI, ESX/ESXi also supports per-target CHAP authentication, which allows you to configure different credentials for each target to achieve greater level of security.

QUESTION NO: 558 In configuing a VMware HA Cluster the System Administrator can configure Admission Control. There are two options: Prevent VMs from being powered on if they violate availability constraints, or Allow VMs to be powered on even if they violate availability constraints. If the System Administrator chooses the opition Allow VMs to be powered on even if they violate availability constraints then which of the following apply in the even of an ESX Host failure (Choose Two)? A. Virhal machines can be powered on until the percentage of cluster resources reaches 25% B. Only Virhal machines with a high restart priority will be restarted on surviving ESX Hosts C. VMware HA restarts Virtual machines on surviving hosts with the most unreserved capacity D. VMware HA cannot guarantee that all VMs from a failed host will be restarted

Answer: C,D Explanation: vSphere Availability Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 12 and 13. You can configure VMware HA to tolerate a specified number of host failures. With the Host Failures Cluster Tolerates admission control policy, VMware HA ensures that a specified number of hosts can fail and sufficient resources remain in the cluster to fail over all the virtual machines from those hosts. In the event of a host failure, the virtual machines running on that host are failed over, that is, restarted on the alternate hosts with the most available unreserved capacity (CPU and memory.)

QUESTION NO: 212 VMware VCP-410: Practice Exam "Pass Any Exam. Any Time." - www.actualtests.com 131 Which of the following conditions could prevent HA from powering on a virtual machine (Choose Two)? A. The VM is connected to the ESX Host CD-ROM drive B. The target host is not compatible with the virtual machine C. Strict admission control is configured D. The VM has a low priority setting

Answer: C,D Explanation: vSphere Availability Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 13. Admission control imposes constraints on resource usage and any action that would violate these constraints is not permitted. Examples of actions that could be disallowed include: Powering on a virtual machine. Migrating a virtual machine onto a host or into a cluster or resource pool. Increasing the CPU or memory reservation of a virtual machine. vSphere Availability Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 22. VM restart priority determines the relative order in which virtual machines are restarted after a host failure. Such virtual machines are restarted sequentially on new hosts, with the highest priority virtual machines first and continuing to those with lower priority until all virtual machines are restarted or no more cluster resources are available.

Answer: D Explanation: D "Multivendor Post" on using iSCSI with VMware vSphere So - setup in 4 easy steps: Step 1 - configure multiple vmkNICs Ok, the first obvious (but we're not making any assumptions) is that you will need to configure multiple physical Ethernet interfaces, and multiple vmkernel NIC (vmkNIC) ports. Step 2 - configure explicit vmkNIC-to-vmNIC binding. To make sure the vmkNICs used by the iSCSI initiator are actual paths to storage, ESX configuration requires the vmkNIC is connected to a portgroup that only has one active uplink and no standby uplinks. This way, if the uplink is unavailable, the storage path is down and the storage multipathing code can choose a different path. Step 3 - configuring the iSCSI initiator to use the multiple vmkNICs Then the final step requires command line configuration. This step is where you assign, or bind, the vmkNICs to the ESX iSCSI initiator. Once the vmkNICs are assigned, the iSCSI initiator uses these specific vmkNICs as outbound ports, rather than the vmkernel routing table. Step 4 - Enabling Multipathing via the Pluggable Storage Architecture VMware ships with a set of native SATPs, and 3 PSPs: Fixed, Most Recently Used (MRU), & Round Robin (RR). Fixed and MRU options were available in VI3.x and should be familiar to readers. Round Robin was experimental in VI3.5, and is supported for production use in vSphere (all versions) Configuring NMP to use a specific PSP (such as Round Robin) is simple and easy. You can do it in the vSphere Client under configuration, storage adapter, select the devices, and right click for properties.

QUESTION NO: 381 Which statement is true about VirtualCenter and the License Server? A. VirtualCenter cannot be installed without an operational License Server online. B.

Answer: D Explanation: ESX Server 3 Installation Guide ESX Server 3.5 and VirtualCenter 2.5, page 30, 49. Location of the License Server VMware recommends that you follow the default installation and place your license server on the same machine as your VirtualCenter Server. This has the advantage of simplicity of setup, as well as guaranteeing VirtualCentertolicense server communications. Change this only if you have a good reason, such as an existing FLEXnet license server. At least one instance of a VirtualCenter license is required for VI Foundation, VI Standard, and VI Enterprise editions. The following VirtualCenter editions are available: VirtualCenter Foundation - This edition lets you manage up to three ESX Server hosts. If you need to manage more than three hosts, upgrade to VirtualCenter edition. VirtualCenter - This is an enterprise level edition that lets you manage up to the system maximum number of hosts. For information about system maximums, see Configuration Maximums for VMware Infrastructure 3.

QUESTION NO: 92 The Runtime Name for a Fibre Channel storage device is equivalent to? A. The Network Address Authority (NAA) name of the device B. The name of the current path to the device in vmhba:C:T:L format C. The Universally Unique Identifier (UUID) to the device D. The name of the first discovered path to the device in vmhba:C:T:L format

Answer: D Explanation: Fibre Channel SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 53. Runtime Name The name of the first path to the device. The runtime name is created by the host. The name is not a reliable identifier for the device, and is not persistent. The runtime name has the following format: vmhba#:C#:T#:L#, where vmhba# is the name of the storage adapter. The name refers to the physical adapter on the host, not to the SCSI controller used by the virtual machines. C# is the storage channel number. T# is the target number. Target numbering is decided by the host and might change if there is a change in the mappings of targets visible to the host. Targets that are shared by different hosts might not have the same target number. L# is the LUN number that shows the position of the LUN within the target. The LUN number is provided by the storage system. If a target has only one LUN, the LUN number is always zero (0). For example, vmhba1:C0:T3:L1 represents LUN1 on target 3 accessed through the storage adapter vmhba1 and channel 0.

Set the Share levd to High for the virtual machine running the application and set all other virtual machines to Low C. Set a Limit equal to the Peak Memory utilization of the virtual machine running the application D. Set a Reservation equal to the configured Memory of the virtual machine running the application

Answer: D Explanation: Memory Provisioning Recommendations for VMware Infrastructure 3 Operational Best Practices page 8. Memory Reservations, Limits, and Shares Memory Reservations are an ESX Server memory management technique used to control how memory is allocated from an either an explicit or implicit resource pool by the VMkernel to a virtual machine or group of virtual machines. Reservations consist of two settings - a reservation, or guaranteed amount of physical memory that will always be available to the virtual machine(s), and a limit, which is the absolute maximum physical memory a virtual machine or group of virtual machines can consume on the host During peak operating hours, by definition more systems and more resources including memory, will be being consumed. Therefore memory reservation is required. By setting a reservation equal to the peak memory utilization, this will guarantee the application receives all memory it requires.

QUESTION NO: 227 Which memory conservation technique allows the secure elimination of redundant copies of memory pages between virtual machines on the host? A. VMkernel Swap B. RAM Overcommit C. Memory Balloon Driver D. Transparent Page Sharing

Answer: D Explanation: Memory Provisioning Recommendations for VMware Infrastructure 3 Operational Best Practices page 7. Transparent Page Sharing is a process executed frequently by the VMkernel that scans physical memory to identify redundant virtual machine memory pages. When a match is found, the physical page is marked read-only. The VMkernel removes the duplicate page from physical RAM and the page table is adjusted to redirect the virtual machine's virtual page back to the read-only page in physical RAM. This mechanism results in increasing memory that is shared among running virtual machines over time.

Failover order: Explicit list of preferred links (uses highest-priority link which is up) 2. 1. Maintains load balancing configuration 2. Good if using a lower bandwidth standby NIC 3. Rolling failover -- preferred uplink list sorted by uptime The uplink with the shortest route - all uplinks are on the same network and so have the same route The next available uplink on the list has not been defined if explicit failover order is not selected

QUESTION NO: 274 What is the meaning of a red, or critical, indicator on a DRS cluster? A. Red clusters are the highest priority and will receive resource allocations first B. At least one host in the cluster is attempting to go into Maintenance Mode C. Yellow clusters will become red after 15 minutes if DRS is unable to dynamically balance the load D. Red clusters indicate virtual machines are using more resources than the fixed reservation allows

Answer: D Explanation: Red DRS Cluster A cluster enabled for DRS becomes red when the tree is no longer internally consistent and does not have enough resources available. For example, a DRS cluster turns red if the virtual machines in a fixed resource pool use more resources than the Reservation of that resource pool allows.

QUESTION NO: 415 A standalone ESX Server with two physical CPUs has two running virtual machines (VMs) labeled VMA and VMB. Each VM has two virtual CPUs. VMA has 4000 CPU shares and VMB has 2000 CPU shares. VMA is continuously using 10% of the ESX Server's CPU resources. VMB attempts to use all CPU resources on the ESX Server. Ignore overhead from the service console. What percentage of the ESX Server's CPU resources will VMB be granted? A. 50% B. 100% C. 33% D. 90%

Answer: D Explanation: Shares specify the relative priority or importance of a virtual machine (or resource pool). If a virtual machine has twice as many shares of a resource as another virtual machine, it is entitled to consume twice as much of that resource when these two virtual machines are competing for resources. Note however, that VMA and VMB are not competing for resources. VMA is only using 10% of resources, so 90% are available for VMB, (D above). If both systems were attempting to use more than 100% of total resources, resources would be allocated according to shares, with VMA (4000 CPU shares) receiving 66% of resources and VMB (2000 CPU shares) receiving 33% of CPU resources, (C above but not applicable since machines are not competing for resources).

QUESTION NO: 170 In Guided Consolidation, a higher Confidence Metric indicates which of the following? A. The displayed destination ESX Server is the best fit from all available ESX Servers B. A given destination ESX Server is a better fit for the source machine C. The source machine is a better candidate for virtualization D. The data collected from the source machine is more reliable

Answer: D Explanation: vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 95. About the Confidence Metric One important metric displayed in the Analysis tab is the Confidence metric. During the analysis phase, performance data about each selected system is collected. This data is used to find a host with resources that match the collected data to determine a recommendation for each candidate. The recommendation indicates how well suited, based on the collected data, a candidate is to a particular virtual machine host system. Confidence refers to the reliability of the recommendation and it is a function of the duration of the analysis. Recommendations based on longer periods of analysis - and therefore more performance data - receive a higher level of confidence.

QUESTION NO: 411 While attempting to start a virtual machine (VM), you get an error message stating that there is insufficient memory available. What can you do to start the VM? A. increase the memory limit of your VM B. decrease the memory limit of your VM C. increase the memory reservation of your VM D. decrease the memory reservation of your VM

Answer: D Explanation: vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 14, 25. Reservation - Is a guaranteed lower bound on the amount of physical memory that the hostreserves for the virtual machine, even when memory is overcommitted. When you power on a virtual machine, the system checks the amount of CPU and memory resources that have not yet been reserved. Based on the available unreserved resources, the system determines whether it can guarantee the reservation for which the virtual machine is configured (if any). This process is called admission control. If enough unreserved CPU and memory are available, or if there is no reservation, the virtual machine is powered on. Otherwise, an Insufficient Resources warning appears. Therefore the reservation should be decreased to allow the VM to start.

QUESTION NO: 435 One of the hosts in a cluster of 10 hosts requires maintenance. This host is currently running two virtual machines (VMs) for a total of 30% CPU utilization. What is the best practice for repairing the hardware? A. place the VMs on the host in Maintenance mode B. place the host in Offline mode C. repair the server while running VMs D. place the host in Maintenance mode

Answer: D Explanation: vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 55. You place a host in maintenance mode when you need to service it, for example, to install more memory. A host enters or leaves maintenance mode only as the result of a user request. Virtual machines that are running on a host entering maintenance mode need to be migrated to another host (either manually or automatically by DRS) or shut down. The host is in a state of Entering Maintenance Mode until all running virtual machines are powered down or migrated to different hosts. You cannot power on virtual machines or migrate virtual machines to a host entering maintenance mode. By placing the host in Maintenance mode you will ensure no Maintenance modems are migrated to this server. [D above]
