CompTIA Server+ (SK0-005) — Question 311

Which of the following is the BEST action to perform before applying patches to one of the hosts in a high availability cluster?

Answer options

• A. Disable the heartbeat network.
• B. Fallback cluster services.
• C. Set the cluster to active-active.
• D. Failover all VMs.

Correct answer: D

Explanation

The best action is to failover all VMs to ensure that they are running on another host while the patches are applied. This minimizes downtime and maintains service availability. The other options either do not directly contribute to VM availability or may disrupt the cluster's functionality.
