Exam 5V0-22.21 topic 1 question 52 discussion

The answer has to be D... the question says, they've been powered down... that means B and C have been taken care of... we are now at the powering up and exiting maintenance mode part of the process.

I think it should be D

Answer D

Answer is D. Disabling retreat mode not necessary for powering on vms. It is for DRS working properly. So, you should first exit maintenance hosts and power on vcenter server. https://www.sbarjatiya.com/notes_wiki/index.php/Powering_off_and_powering_on_a_VSAN_cluster

Exit each host from maintenance, C is only if something didn't go accordingly to procedures which is not the case here.

So, Cluster is relocated. 1. Power on servers, not by A. 2. Hosts start it is needed to exit maintenance mode - not B, but not either because it should be done by esxcli command. 3. vCLS should be disabled retreat mode.

D https://kb.vmware.com/s/article/2142676 To power on the vSAN cluster: 1)Boot up all ESXi nodes that is part of the cluster either through remote console session or physically. 2)Connect to each ESXi host and exit maintenance mode using one of these options: a)Using the vSphere Host Client b)From the shell using this command: esxcli system maintenanceMode set -e false 3)If you followed the recommendation from step 2 of the shutdown process login into node 1 or the node you notated vCenter resides via the Web Client and power on your vCenter Server 4)Connect to your vCenter Server using the vSphere Web Client. Note: It may take a few minutes for vCenter Server to become available again. 5)Do a quick health check on the vSAN cluster. Check for network partitions and resyncing components. For more information, see: The Monitoring Virtual SAN section of the Administering VMware Virtual SAN guide. The Check vSAN Health section of the Administering VMware Virtual SAN guide. 6)Power on the remaining virtual machines in the vSAN cluster.

It is not possible to put all hosts in Maintenance Mode with No Data Migration without disable Retreat Mode. The task still pending until all vCLS VM be shutdown manually.

Restart the vCenter Server VM if it is powered off. Wait for the vCenter Server VM to be powered up and running to disable vCLS retreat mode

Afterwards, the operations engineer needs to bring up the vSAN cluster again. "Which action is part of this process?" D: exit Maintenance mode.

If we are in the stage of powering up the cluster it should be D https://kb.vmware.com/s/article/2142676#:~:text=Powering%20on%20the%20vSAN%20cluster,remote%20console%20session%20or%20physically.&text=4)Connect%20to%20your%20vCenter,Server%20to%20become%20available%20again.
