What is the purpose of the NX/XD CPU feature present in most modern Intel and AMD processors?

The feature adds a layer of security by marking areas of memory as non-executable.

What component of virtualization controls all physical memory, and thus has the ability to make any unused memory pages in each guest available for other virtual machines or the host computer?

The hypervisor

What statement regarding virtual disk types is accurate?

A dynamic disk does not immediately allocate the configured size of the disk.

When using the VMware Horizon software, where do client desktop operating systems run?

They run on a VMware vSphere ESXi host.

Cloud services are highly reliant upon the use of virtualization technology.

True

Many of the concepts used in today's virtualization products date back to IBM mainframe computers for the 1970s.

True

The hypervisor intercepts and processes requests coming from the guest operating systems and then returns the results back to the virtual machine.

True

What is the most commonly used form of a Storage Area Network?

An iSCSI network

A virtual machine can't share the use of a network adapter with the host.

False

In virtualized computing, a single computer is capable of supporting a single operating system.

False

You are employed by a cloud service provider that offers virtual machine services along with virtual switches, storage, firewalls, and other virtual devices. What type of cloud environment does your employer sell?

Infrastructure as a Service

What format enables a virtual machine to be moved between virtualization platforms, and is often used for deploying virtual appliances?

Open Virtualization Format (OVF)

What open standard was developed as a result of collaboration between NASA and Rackspace?

OpenStack

The VDI disk file format is native to what virtualization platform?

Oracle VirtualBox

What type of cloud computing service provides hardware infrastructure along with necessary operating system software for running client applications?

What virtualization technology makes it possible to avoid overhead associated with software-managed shadow page tables?

Second Level Address Translation (SLAT)

What is the oldest version of Windows Server to support the use of Microsoft's Hyper-V product?

Windows Server 2008

What hypervisor uses a special guest called Domain 0 that loads along with the hypervisor and is used to directly access the hardware?

Xen

Which of the following does an operating system installed in a guest virtual machine do?

interacts with hardware through the hypervisor

You have been tasked with creating a virtual machine that will require access to the Internet, but should be prevented from sending and receiving packets directly from the physical network. What network mode should be used?

shared (NAT) mode

What feature, supported by VMWare, allows the live migration of a running VM from one host to another?

vMotion

Why are type-1 hypervisors more efficient than type-2 hypervisors?

A type-1 hypervisor accesses the physical hardware directly.

What statement regarding the use of Hyper-V is accurate?

Hyper-V requires a 64-bit processor with hardware virtualization support.

An ISO image file uses what format to store a disc's contents in a single file on a computer?

ISO 9660

What is the purpose of a shadow page table when a hypervisor is used?

It tracks the memory pages allocated by each guest VM.

When a Xen based guest VM makes a request for a hardware resource, such as reading from a disk, where is the request sent to?

NOT It is sent to the host operating system, which then handles the request.,It is sent directly to the hardware on the host machine.

Your work environment consists of a large number of Mac OS X based devices. The developers in your network have requested virtualization software be installed for their use. What product should you use?

NOT Xen, VMware Workstation

You are working in a VMware vSphere based environment, and have been asked to create a parent virtual machine that can be shared amongst many users. One of the requirements of this desired setup is that individual user changes must be kept separate. What is the best implementation based on the requirements given?

The parent virtual machine should be configured to make use of linked clones.

What is NOT a product designed specifically for the virtualization of applications within a VDI environment?

VMware Fusion

You have been tasked with creating a virtual machine that will be providing hosted services on the physical network, and possibly the Internet. What network mode should be used?

bridged mode
