An administrator has to perform maintenance on one of the hosts in a three-node vSAN Cluster. Which maintenance mode option will give the administrator the best availability for the VMs with the…

Question

Options

• AMigrate all VMs and their storage from the host to a different storage system
• BFull data migration
• CMigrate all VMs and their storage from the host to a different vSphere cluster
• DEnsure accessibility

• A
  8% (5)
• B
  14% (9)
• C
  3% (2)
• D
  75% (47)

Explanation

Ensure Accessibility (D) is correct because it keeps VM storage components on the host intact while simply marking those components as temporarily unavailable - vSAN redistributes just enough data to maintain quorum and accessibility without moving everything, minimizing data transfer and effort. Full data migration (B) evacuates all data from the host entirely, which is the safest option for extended maintenance but requires massive data transfer across the cluster - overkill for a short maintenance window. Options A and C describe migrating VMs and storage to a completely different storage system or cluster, which are not standard vSAN maintenance mode options and would require far more administrative effort and infrastructure. Memory tip: Think "Ensure Accessibility = minimum movement" - vSAN just ensures your VMs stay accessible, not that their data gets moved, making it the lazy (but smart) admin's choice for quick maintenance.
