Exam 5V0-22.21 topic 1 question 9 discussion

Actual exam question from VMware's 5V0-22.21
Question #: 9
Topic #: 1
[All 5V0-22.21 Questions]

During yesterday's business hours, a cache drive failed on one of the vSAN nodes. The administrator reached out to the manufacturer and received a replacement drive the following day. When the drive failed, vSAN started a resync to ensure the health of data, and all objects are showing a healthy and compliant state. The vSAN administrator needs to replace the failed cache drive.
Which set of steps should the vSAN administrator take?

  • A. Remove the existing vSAN disk group, and physically replace the device. Then, check to verify that the ESXi host automatically detects the new device. Afterwards, manually recreate the Disk Group.
  • B. Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.
  • C. Physically replace the failed cache device, and vSAN will automatically allocate the storage. Then, rebalance the cache layer.
  • D. Place the disk group into maintenance mode, and select Full Data Migration. Then, physically replace the failed cache device. Afterwards, vSAN will rebuild the disk group automatically.

On the Configure tab, click Disk Management under vSAN. Select the entire disk group that contains the flash caching device that you want to remove. vSAN does not allow you to remove the cache disk. To remove the cache disk, you must remove the entire disk group. Click More options and click REMOVE. In the Remove Disk Group dialog box, select any of the following data migration mode to evacuate the data on the disks. Full data migration - Transfers all the data available on the host to other hosts in the cluster. Ensure accessibility - Transfers data available on the host to the other hosts in the cluster partially. During the data transfer, all virtual machines on the host remains accessible. No data migration - There is no data transfer from the host. At this time, some objects might become inaccessible. Click GO TO PRE-CHECK to find the impact on the cluster if the object is removed or placed in maintenance mode. Click REMOVE to remove the disk group.

If you decommission the flash caching device without removing it from vSAN first, vSAN uses smaller amount of cache than expected. As a result, the cluster performance becomes degraded.
