Correct Answer: A

Clone a Virtual Machine in the vSphere Client

Cloning a virtual machine creates a duplicate of the virtual machine with the same configuration and installed software as the original. Optionally, you can customize the guest operating system of the clone to change the virtual machine name, network settings, and other properties. This prevents conflicts that can occur if a virtual machine and a clone with identical guest operating system settings are deployed simultaneously.

Prerequisites

You must be connected to vCenter Server in order to clone a virtual machine. You cannot clone virtual machines if you connect directly to an ESXi host.

Datastore Cannot Enter Maintenance Mode You place a datastore in maintenance mode when you must take it out of usage to service it. A datastore enters or leaves maintenance mode only as a result of a user request. Problem A datastore in a datastore cluster cannot enter maintenance mode. The Entering Maintenance Mode status remains at 1%. Cause One or more disks on the datastore cannot be migrated with Storage vMotion. This condition can occur in the following instances.

1.

Storage DRS is disabled on the disk.

2.

Storage DRS rules prevent Storage DRS from making migration recommendations for the disk. Solution

1.

If Storage DRS is disabled, enable it or determine why it is disabled. See Storage DRS is Disabled on a Virtual Disk for reasons why Storage DRS might be disabled.

2.

If Storage DRS rules are preventing Storage DRS from making migration recommendations, you can

remove or disable particular rules.

a In the vSphere Client inventory, right-click the datastore cluster and select Edit Settings.

b Select Rules and click the rule.

c Click Remove.

d Click OK.

Alternatively, if Storage DRS rules are preventing Storage DRS from making migration recommendations,

you can set the Storage DRS advanced option IgnoreAffinityRulesForMaintenance to 1.

a In the vSphere Client inventory, right-click the datastore cluster and select Edit Settings.

b Select SDRS Automation and click Advanced Options.

c Enter 1 in the Value column for IgnoreAffinityRulesForMaintenance.

d Click OK.

Correct Answer: B

The requirement for this specific storage solution has snapshot support, and vFlash Read cache. For this you need a virtual mode raw device mapped LUN. RDM, which permits the use of existing SAN commands, is generally used to improve performance in I/O-intensive applications. RDM can be configured in either virtual compatibility mode or physical compatibility mode. Virtual mode provides benefits found in VMFS, such as advanced file locking and snapshots. Physical mode provides access to most hardware functions of the storage system that is mapped

Correct Answer: AB

Disable Unexposed Features VMware virtual machines are designed to work on both vSphere systems and hosted virtualization platforms such as Workstation and Fusion. Certain VMX parameters do not need to be enabled when you run a virtual machine on a vSphere system. Disable these parameters to reduce the potential for vulnerabilities. Prerequisites Turn off the virtual machine. Procedure
