• Question 172:

  Refer to the Exhibit.

  

  An administrator is configuring a storage device as shown in the Exhibit.

  What is the expected effect on the stated device after running the command?

  A. I/O will rotate on all storage targets regardless of port group state.

  B. I/O will rotate on all storage targets that are Active Optimized state only.

  C. I/O will rotate on all storage targets that are Active Unoptimized state only.

  D. I/O will rotate on all storage targets that are on Available Nodes only.

  Correct Answer: B

  When the command is run, I/O will rotate on all storage targets regardless of port group state.

• Question 173:

  An administrator needs to recover disk space on a previously-used thin provisioned virtual disk. The volumes where the administrator needs to recover the disk blocks are on VAAI- compliant storage arrays. Which two actions should the administrator take accomplish this task? (Choose two.)

  A. Perform a Storage vMotion to another volume in order to force free space recovery to occur. This recreates the volume in a new location and recovers all unused space.

  B. Use VMware Converter to migrate the virtual machine to a new datastore. This will recreate the volumes and recover all unused space.

  C. Issue the vmkfstools -vmfs unmap command within the VMFS volume directory on the ESXi host console.

  D. Execute the esxcli storage vmfs unmap command.

  Correct Answer: BD

• Question 175:

  Where is a Virtual SAN Fault Domain configured?

  A. VMware Virtual SAN Cluster configuration

  B. VMware High Availability Cluster configuration

  C. Distributed Resource Scheduler configuration

  D. Datacenter Advanced Settings configuration

  Correct Answer: A

  If your Virtual SAN cluster spans across multiple racks or blade server chassis in a data center and you want to make sure that your hosts are protected against rack or chassis failure, you can create fault domains and add one or more hosts to it.

  A fault domain consists of one or more Virtual SAN hosts grouped together according to their physical location in the data center. When configured, fault domains enable Virtual SAN to tolerate failures of entire physical rack as well as failures of a single host, capacity device, network link or a network switch dedicated to fault domains. Fault domains cannot be configured for stretched or metro clusters.

  The number of failures your cluster can tolerate depends on the number of failures a virtual machine is provisioned to tolerate. For example, when a virtual machine is configured with Number of failures to tolerate=1 and using multiple fault domains, Virtual SAN can tolerate a single failure of any kind and of any component in a fault domain, including the failure of an entire rack. When you configure fault domains on a rack and provision a new virtual machine, Virtual SAN ensures that protection objects, such as replicas and witnesses are placed on different fault domains. If, for example, a virtual machine's storage policy is Number of failures to tolerate=n, Virtual SAN requires a minimum of 2*n+1 fault domains in the cluster. When virtual machines are provisioned in a cluster with fault domains using this policy, the copies of the associated virtual machine objects are stored across separate racks.

• Question 176:

  Which two statements are true regarding Virtual SAN Fault Domains? (Choose two.)

  A. They enable Virtual SAN to tolerate the failure of an entire physical rack.

  B. Virtual SAN ensures that no two replicas are provisioned on the same domain.

  C. Virtual SAN ensures that all replicas are provisioned on the same domain.

  D. They require VMware High Availability (HA) to ensure component distribution across domains.

  Correct Answer: AB

  A fault domain consists of one or more Virtual SAN hosts grouped together according to their physical location in the data center. When configured, fault domains enable Virtual SAN to tolerate failures of entire physical rack as well as failures of a single host, capacity device, network link or a network switch dedicated to fault domains. Fault domains cannot be configured for stretched or metro clusters.

• Question 177:

  An administrator is configuring virtual machines to use Worldwide Port Names (WWPNs) to access the storage. Which two conditions are required? (Choose two.)

  A. The switches in the fabric must be N-Port ID Virtualization aware.

  B. The virtual machines must be using passthrough Raw Disk Mapping (RDMp).

  C. The virtual machines must be using Virtual Machine Disk (VMDK).

  D. The switches in the fabric must be Storage I/O Control aware.

  Correct Answer: AB

  To configure virtual machines to use WWPNs, you have to set N-Port ID virtualization aware setting on the switches in the fabric and you should also make sure that the virtual machines must be using passthrough raw disk mapping.

• Question 178:

  An administrator created a six node Virtual SAN cluster, created a fault domain, and moved three of the six nodes into that domain.

  A node that is a member of the fault domain fails.

  What is the expected result?

  A. The remaining two fault domain members are treated as failed.

  B. The remaining two fault domain members stay protected by the domain.

  C. One of the non-member nodes will be automatically added to the fault domain.

  D. VMware High Availability will restart virtual machines on remaining nodes in the domain.

  Correct Answer: A

  When the member of the fault domain fails, the remaining two fault domain members are treated as failed too.

• Question 179:

  Which two solutions require Physical Mode Raw Device Mapping (RDM)? (Choose two.)

  A. Direct access to the storage array device

  B. Virtual Machine Snapshots

  C. Hardware Acceleration

  D. Guest Clustering across ESXi hosts

  Correct Answer: AD

  Normally, Direct access to storage array device and guest clustering across ESXi hosts required the use of Physical Mode raw device mapping.

• Question 180:

  What is the corresponding VAAI support status in the vSphere Web Client?

  B. Supported

  C. Not supported

  D. Unsupported
