Actual exam question from VMware's 5V0-21.21
Question #: 15
Topic #: 1
[All 5V0-21.21 Questions]

An administrator has received an alert indicating that a single capacity device is close to failing within the production vSAN Cluster. The administrator must now complete preemptive maintenance on the vSAN Cluster without impacting the availability of workloads or vSAN File Services.
The following information is known about the vSAN Cluster:
✑ vSAN 7.x Cluster
✑ vSAN node count: 8
✑ De-Duplication and Compression: Enabled.
✑ Encryption: Disabled
Current Utilization: 45%

✑ Disk Groups: 2
✑ Devices per node: 2 x 400 GB SSD, 6 x 1.8 TB SSD
Which three steps should the administrator take to successfully complete the task? (Choose three.)

  • A. Remove the affected Disk Group from the vSAN Cluster, and choose Full Data Migration.
  • B. Replace the failed disk with a storage device that is identical in class and capacity.
  • C. Remove the affected Disk Group from the vSAN Cluster, and choose No Data Migration.
  • D. Replace the failed disk with a storage device that is identical in class but smaller in capacity.
  • E. Put the affected vSAN host into maintenance mode to physically replace the storage device.
  • F. Remove the affected Disk from the Disk Group, and choose Full Data Migration.

I am going BCE. Technically you shouldn't have to put the host in maintenance mode to replace a disk. When vSAN detects a disk is going to failure it will automatically move that data and stop using that disk. In this case it would stop using the disk group because of compression. See https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.virtualsan.doc/GUID-AA72CA1D-803D-4D1D-87BB-E7D86EC947D2.html calling out when replacing a failed disk group, use the "No Data Migration Option".

I choose B,E,F If you upgrade the capacity device, verify the following requirements: - Verify that the cluster contains enough space to migrate the data from the capacity device. - Place the host in maintenance mode. See Place a Member of Virtual SAN Cluster in Maintenance Mode. "Select the flash capacity device or magnetic disk, and click Remove selected disk(s) from disk group." https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-4E3390C1-6C50-49E5-AEB6-C9BC037979A1.html

I disagree on C. The url you listed lists "No Data Migration" option for FAILED drive. In this question is is talking about drive that is "close to failing". This means that all of the data is still accessible and user should be able to migrate it off before the disk fails. We also don't want to "impact the availability" of the workload, which means that we don't want vSAN to start rebuilding data only 60 min after the disk group is removed.
