You suspect that there has been a physical network misconfiguration. What characteristic of ESXi can be used to discover neighboring physical switches and help troubleshoot the possible misconfiguration?

CDP/LLDP Cisco Discovery Protocol (CDP) and Link Layer Discovery Protocol (LLDP) are link layer network protocols which identify adjacent network switches and provide information such as link speeds, duplex, make/model.

Your boss asks what provides virtual machines with the virtual hardware in an ESXi environment. Which item is central to this provisioning?

Hypervisor In computing, a hypervisor or virtual machine monitor (VMM) is a piece of computer software, firmware or hardware that creates and runs virtual machines

You are planning to add a new datastore to your ESXi host. Which two types of network-attached datastores are supported?

NFS and iSCSI VMFS is a high-performance cluster file system optimized for virtual machines. You can deploy a VMFS datastore on any SCSI-based local or networked storage device, including NFS, Fibre Channel, Fiber Channel over Ethernet (FCoE) and iSCSI SAN equipment. NFS

A storage administrator reports that a network storage device is running out of space and needs to move some virtual machine disk files to another datastore without disruption. What is a viable solution?

Storage vMotion vSphere Storage vMotion enables live migration of virtual machine disk files within and across storage arrays without service disruptions.

You must ensure that a Windows NT virtual machine running a business-critical application continues to run in the event of a host failure. Which feature can meet your objective?

The correct answer is Fault Tolerance (FT) Fault Tolerance (FT) provides continuous availability for applications in the event of server failures by creating a live shadow instance of a virtual machine that is always up-to-date with the primary virtual machine. In the event of a hardware outage, FT automatically triggers failover—ensuring zero downtime and preventing data loss.

Your boss has asked what virtual switches are used for. Which option would be the best response?

To connect your virtual machines to the physical network. vSphere supports the use of virtual switches to manage network traffic to and from virtual machines and the physical network.

For security, you need to separate your virtual machine network traffic between the Finance and Engineering sub-networks. Which networking feature can help achieve this?

Virtual LANs (VLANs) enable a single physical LAN segment to be further segmented so that groups of ports are isolated from one another as if they were on physically different segments.

Your company has a machine that runs a legacy application on Windows Server 2003 R2 that must be virtualized. Which option will help you meet this requirement?

to Perform a Physical to Virtual (P2V) conversion of the Windows Server 2003 R2 physical machine using the VMware vCenter Converter tool.

Your network administrator has planned maintenance that will stop all network traffic to your shared storage. Which vSphere feature will function without shared storage?

vMotion With the release of version 5.1, VMware introduced some extra functionality to the vMotion platform. One of these enhancements enables vMotion to run in environments without shared storage.
