[All 5V0-21.21 Questions]

An administrator is reviewing the root cause analysis of a failure event that resulted in vSAN Data Loss. The following information is known about the event:

1. The RAID battery-replacing procedure on one of the first vSAN cluster node took much more time than the vSAN administrator predicted.
2. The only Storage policy has a Primary level of Failures To Tolerate = 1.
3. Whilst the first host was in maintenance mode, another node failure occurred, causing da-ta loss in the vSAN cluster.

The administrator needs to update the procedure for completing maintenance on the cluster.

Which Maintenance Mode option should the administrator choose to ensure that data loss does not occur in the future?

  • A. No data migration
  • B. Ensure accessibility
  • C. No data migration with selected option 'Move powered-off and suspended virtual machines to other hosts in the cluster'

This should be B. https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.virtualsan.doc/GUID-521EA4BC-E411-47D4-899A-5E0264469866.html

Shouldn't it be Full Data Migration, per the link you provided. Question says that one host is in maintenance mode, and requirement is that the cluster needs to be fully operational if another node fails. Ensure Accessibility - If a failure occurs while the host is in maintenance mode and the Primary level of failures to tolerate is set to 1, you might experience data loss in the cluster.

Have to agree here, B will cause the same result if another node goes down again whilst a node is already in maintenance. D should be the correct answer in my opinion. It's the only option to ensure there is no data loss.
