VMware VCA6-DCV 1V0-621 Questions & Answers

• Question 11:

  An operator installs an OS to a new virtual machine (VM) using a DVD inserted into the ESXi host. Later, the operator notices that a vMotion migration on the new VM fails.

  What action needs to be taken in order for the vMotion migration to succeed?

  A. initiate a high-priority vmotion

  B. Add a virtual CD/DVD drive to the VM.

  C. Add a CD/DVD drive to the target ESXi host

  D. Disconnect the CD/DVD drive from the VM.

  Correct Answer: D

• Question 12:

  What does Distributed Power Management (DPM) do when workloads increase during peak times?

  A. Migrates virtual machines to hosts to balance power consumption

  B. Brings powered-down hosts back online

  C. Brings powered-down virtual machines back online

  D. Adds additional resources to DPM-enabled clusters to handle workload

  Correct Answer: B

  Explanation: VMware DPM is a function provided by DRS to reduce energy consumption during off peak times. When enabled, DPM monitors the environment for activity on the cluster and will consolidate VMs to as few ESXi hosts as are required to host the workloads and still satisfy availability constraints. After the workloads have been consolidated, DPM shut downs hosts into standby mode.DPM automates and optimizes energy management in the datacenter, so that an administrator can cut the power costs during off peak times of resource utilization. When utilization increases, DPM automatically restarts the ESXi hosts that have been put into standby, thereby fulfilling the demand for resources.
