VMware vSphere 6.5 Foundations (VCP6.5-DCV) — Question 40

An administrator creates a DRS cluster of eight ESXi 6.x hosts. There are 10 virtual machines balanced across the hosts. An attempt to place the first host into maintenance mode fails.
What are two reasons that the host failed to enter maintenance mode? (Choose two.)

Answer options

• A. The DRS cluster Automation Level is set to Partially Automated mode.
• B. One of the virtual machines on the ESXi Host entering maintenance mode is configured with a DRS Host affinity rule Should run on hosts in group.
• C. One of the virtual machines on the ESXi Host entering maintenance mode is configured with a DRS Host affinity rule Must run on hosts in group.
• D. One of the virtual machines on the ESXi Host entering maintenance mode is configured with an individual Automation Level set to Partially Automated.

Correct answer: A, D

Explanation

The correct answers are A and D. If the DRS cluster's Automation Level is set to Partially Automated, it might not automatically migrate VMs off the host, preventing maintenance mode entry. Additionally, if a VM has an individual Automation Level set to Partially Automated, it won't be migrated even if the cluster is set to a different mode, causing the maintenance mode attempt to fail. Options B and C regarding DRS Host affinity rules do not prevent entering maintenance mode under the given circumstances.
