Exam 5V0-22.23 topic 1 question 21 discussion

Answer is correct. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-monitoring.doc/GUID-89211E74-69A5-4126-AABC-A70984C56A8F.html

Placing all ESXi hosts into maintenance mode ensures that no workloads are running on the hosts and that the vSAN cluster can be safely shut down without any issues. It helps to prepare the environment for a clean shutdown and ensures that all resources are appropriately managed during the power outage.

In fact, this question is strange : tasks listed in A, B & C are in fact managed by the Shutdown Cluster Wizard. See following link for reference : https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-monitoring.doc/GUID-89211E74-69A5-4126-AABC-A70984C56A8F.html And of course, if you shutdown the vCenter (Answer D), you cannot access the wizard. The only answer I could see if C, because it is the first task realized by the wizard, and the first one in a manual shutdown.

C. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-monitoring.doc/GUID-31B4F958-30A9-4BEC-819E-32A18A685688.html

Correct answer is C https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-monitoring.doc/GUID-31B4F958-30A9-4BEC-819E-32A18A685688.html

A. Place all ESXi hosts into maintenance mode Placing hosts into maintenance mode will trigger the vMotion of virtual machines to other hosts in the cluster, ensuring a controlled and graceful evacuation of VMs. This is an essential step to avoid data unavailability or disruption during the cluster shutdown.

But of the 4 answers, "A" is the most valid. No harm putting ESX into maintenance mode though it is not necessary based on the notes below https://docs.vmware.com/en/VMware-vSphere/8.0/vsan-administration/GUID-0D24C5BA-0248-4E3A-ADA3-33FF551C78F5.html
