Which strategy should be used to achieve this goal?

An administrator would like to add a new server into an existing vSphere cluster. The servers are running Intel processors. The administrator needs to ensure that the new server can be added to the cluster with the same processor baseline as the existing servers.

Which strategy should be used to achieve this goal?
A . Fault Tolerance
B . Enhanced vMotion Compatibility
C . vSphere vMotion
D . vSphere High Availability

Answer: B

What is a possible cause of this event?

A vSphere administrator sees the alarm:

vSphere HA virtual machine failed to failover

This occurred for virtual machines (VMs) in a cluster with vSphere High Availability (HA) enabled. The guest operating system on the VMs did not report a power failure.

What is a possible cause of this event?

A. The host is still running but has disconnected from the network.

B. The VMs cloning operations did not complete.

C. A reboot of vCenter Server impacted vSphere HA.

D. The VMs encountered an error during migration using vSphere vMotion.

Answer: A

What is the result of this action?

Refer to the exhibit: An administrator deletes the Service 1.5 snapshot.

What is the result of this action?
A . Reversion to Service 1 snapshot, and Service 2 snapshot will remain.
B . Reversion to Service 1 snapshot, and Service 2 snapshot will be deleted.
C . Reversion to Service 2 snapshot, and Service 1 snapshot will be deleted.
D . Deletion of all snapshots.

Answer: A

What is a benefit of VMware vSphere Storage APIs – Data Protection?

What is a benefit of VMware vSphere Storage APIs – Data Protection?
A . It enables centralized, off-host. LAN-free backup of vSphere virtual machines.
B . It allows backup of a virtual machine with a backup agent in the guest O
D . It increases ESX host resources to do backup processing.
E . It facilitates decentralized, on-host, LAN-free backup of vSphere virtual machines.

Answer: A

Which action should the administrator take to meet this goal?

An administrator needs to upgrade the guest operating system installed in a virtual machine. The administrator wants to safely ensure that the selected operating system is supported by ESXi.

Which action should the administrator take to meet this goal?
A . Perform a guest OS and product search In the VMware Compatibility Guide.
B . Look in the guest OS version drop-down menu of the V
D . Snapshot the VM before performing the operating system upgrade.
E . Check the web page of the guest operating system vendor.

Answer: C

Which problem is solved by migrating virtual machines (VMs) using vSphere vMotion?

Which problem is solved by migrating virtual machines (VMs) using vSphere vMotion?
A . A vSphere cluster that needs to be upgraded without any VM downtime.
B . A problem that occurred during VM patching and a roll-back is needed.
C . The names of the VM files that do not match the inventory name of the V
E . Heavy storage traffic and latency that are concentrated in a few datastores.

Answer: D
