  ---

  Before changing the name, verify connectivity to ESXi host where the virtual machine resides and that its inventory list is accessible. Reference: https://kb.vmware.com/selfservice/microsites/search.do?language=en_USandcmd=displayKCandexternalId=1003742

• Question 185:

  An administrator is attempting to power on a virtual machine, but the task is hanging at 95%. What three scenarios best explain why this problem is happening? (Choose three.)

  A. A virtual machine question is currently being posed to the administrator.
  B. Another task for the virtual machine or other component is already in progress.
  C. The VMware High Availability cluster has insufficient resources to guarantee failover.
  D. The host has lost access to the storage device containing the virtual machine files.
  E. The host is under resource contention and unable to power on the virtual machine.
  A. A virtual machine question is currently being posed to the administrator.
  B. Another task for the virtual machine or other component is already in progress.
  C. The VMware High Availability cluster has insufficient resources to guarantee failover.

  ---

  It might be that another task for the virtual machine or another component is already in progress or that the Vmware HA cluster has insufficient resources to guarantee failover.

• Question 186:

  Which two statements are correct when turning off a Distributed Resource Scheduler (DRS) Cluster? (Choose two.)

  A. The resource pool hierarchy of the DRS cluster is maintained.
  B. The resource pool hierarchy of the DRS cluster is removed.
  C. The affinity settings of the DRS cluster are removed and not maintained when DRS is re-enabled.
  D. The affinity settings of the DRS cluster are maintained when DRS is re-enabled.
  B. The resource pool hierarchy of the DRS cluster is removed.
  C. The affinity settings of the DRS cluster are removed and not maintained when DRS is re-enabled.

  ---

  When DRS is disabled, the cluster's resource pool hierarchy and affinity rules are not reestablished when DRS is turned back on. So if you disable DRS, the resource pools are removed from the cluster. Reference: http://www.vladan.fr/vcp6-dcv-objective-9-2-configure-advanced-vsphere-drs-features/

• Question 187:

  An administrator is trying to determine why a newly-created ESXi host cannot see the configured iSCSI LUNs. The administrator suspects that a colleague entered the iSCSI Qualified Name (IQN) incorrectly in the iSCSI software initiator settings. The IQN entered is: iqn.iscsi.vmware.com.2015-06:lun01

  Which two statements explain why the IQN address is incorrect? (Choose two.)

  A. The domain name is written correctly.
  B. The date format is written incorrectly.
  C. The LUN identifier is in the wrong location.
  D. The date is in the wrong location.
  C. The LUN identifier is in the wrong location.
  D. The date is in the wrong location.

• Question 188:

  A mission-critical virtual machine built on vSphere 4.1 needs to be moved to an ESXi 6.x host. Which virtual hardware version is needed to move the virtual machine without upgrading?

  A. 6
  B. 7
  C. 10
  D. 11
  B. 7

  ---

  You need version 7 to upgrade a VM on vSphere 4.1 to ESXi 6.x host Reference: https://kb.vmware.com/selfservice/microsites/search.do?language=en_USandcmd=displayKCandexternalId=1003746

• Question 189:

  When attempting to power on a virtual machine, the following error message is shown:

  Unable to access a file since it is locked

  What are two actions that can be taken to address this situation? (Choose two.)

  A. Investigate only the logs for the virtual machine.
  B. Investigate the logs for both the host and the virtual machine.
  C. Power off the other virtual machines on the host, then retry the operation.
  D. Reboot the host the virtual machine is running on.
  A. Investigate only the logs for the virtual machine.
  D. Reboot the host the virtual machine is running on.

• Question 190:

  What are three goals of resource management within a cluster? (Choose three.)

  A. To prevent virtual machines from monopolizing resources and to guarantee predictable service rates.
  B. To exploit undercommitted resources and overcommit with graceful degradation.
  C. To provide solutions to potential problems that you might encounter when using vCenter Server.
  D. To control the relative importance of virtual machines and provide flexible dynamic partitioning.
  E. To provide additional network administration capabilities.
  A. To prevent virtual machines from monopolizing resources and to guarantee predictable service rates.
  B. To exploit undercommitted resources and overcommit with graceful degradation.
  D. To control the relative importance of virtual machines and provide flexible dynamic partitioning.

  ---

  When managing your resources, you should be aware of what your goals are.

  In addition to resolving resource overcommitment, resource management can help you accomplish the following:

  Performance Isolation--prevent virtual machines from monopolizing resources and guarantee predictable service rates.

  Efficient Utilization--exploit undercommitted resources and overcommit with graceful degradation.

  Easy Administration--control the relative importance of virtual machines, provide flexible dynamic partitioning, and meet absolute service-level agreements.
