4. Question 4 · 1

   A vSAN administrator is implementing deduplication and compression on a vSAN all-flash cluster but wants the VMs to remain operational. The details are as follows: ✑ There are 4 nodes in the vSAN cluster. ✑ Existing VMs use a RAID-5 storage policy. Which action should the vSAN administrator take to meet this goal?

   Choose one answer.

   • Use explicit fault domains.
   • Enable TRIM/UNMAP.
   • Change the existing VM storage policy to RAID-6.
   • Use the Allow Reduced Redundancy option.

5. Question 5 · 1

   A vSAN administrator was presented with 30 additional vSAN ReadyNodes to add to an existing vSAN cluster. There is only one administrator to complete this task. What is the fastest approach?

   Choose one answer.

   • Use a Host Profile that was extracted from an existing host.
   • Clone the ESXi boot partition to all new hosts, since the hardware is identical.
   • Run vim-cmd to capture, and apply the configuration from an existing host.
   • Launch Quickstart to Add Hosts to a vSAN Cluster

6. Question 6 · 1

   Which tool should be used to identify vSAN unassociated objects?

   Choose one answer.

   • vSphere Host Client
   • vSphere CLI
   • vsantop
   • PowerCLI

7. Question 7 · 1

   What are two purposes of a vSAN storage policy (Choose two.)

   Choose all answers that apply.

   • To determine vSAN encryption level
   • To enable TRIM/UNMAP
   • To define how the VM storage objects are provisioned
   • To guarantee the required level of service
   • To enable deduplication and compression

8. Question 8 · 1

   A new host with local storage devices has been added to a vSAN cluster. Now, the administrator would like to increase the capacity of the vSAN datastore. What must be done to the new host to accomplish this goal?

   Choose one answer.

   • Configure a RAID set on the storage controller.
   • Create one or more disk groups.
   • Delete all existing partitions.
   • Perform a storage device rescan.

9. Question 9 · 1

   The objects on a 4-node vSAN cluster are assigned a RAID-5 policy. A network outage occurs, causing host one to lose connectivity with the rest of the cluster. Seventy-five minutes have elapsed. What is the health state of the objects?

   Choose one answer.

   • Reduced availability with no rebuild
   • Non-availability related incompliance (non-compliance)
   • Reduced availability
   • Reduced availability with no rebuild - delay timer

   Read explanation

   Minimum number of hosts required for Raid 5: 2n+1. Reduced availability - active rebuild: The object has suffered a failure, but it was configured to be able to tolerate the failure. I/O continues to flow and the object is accessible. vSAN is actively working on re-protecting the object by rebuilding new components to bring the object back to compliance. Reduced availability with no rebuild: The object has suffered a failure, but VSAN was able to tolerate it. For example: I/O is flowing and the object is accessible. However, VSAN is not working on re-protecting the object. This is not due to the delay timer (reduced availability - no rebuild - delay timer) but due to other reasons. This could be because there are not enough resources in the cluster, or this could be because there were not enough resources in the past, or there was a failure to re-protect in the past and VSAN has yet to retry.

10. Question 10 · 1

    Which two actions are recommended when adding a host to a vSAN cluster? (Choose two.)

    Choose all answers that apply.

    • Disable vSphere High Availability (HA).
    • Create uniformly-configured hosts.
    • Reference the VMware Compatibility Guide.
    • Disable vSphere Cluster Services (vCLS).
    • Disable vSAN performance service.

11. Question 11 · 1

    An existing vSAN cluster has this specification: ✑ Four ESXi hosts with all flash configuration ✑ Each with two disk groups ✑ Each disk group with one cache device and four capacity devices ✑ There are five more device slots available The CTO would like to provision new applications, and these will need more capacity and performance. Which two methods may be used by the vSAN administrator to meet this goal? (Choose two.)

    Choose all answers that apply.

    • Adding faster cache devices
    • Adding one more disk group per host with the same configuration
    • Replacing all cache devices by a larger device
    • Adding an ESXi host with identical device configuration
    • Replacing all capacity devices by a larger device
