2V0-21.23 Question 50
Single answerA company has configured VMware vSphere High Availability (HA) for their virtual environment. During a planned maintenance event, one of the ESXi hosts in the cluster is intentionally powered off. Following this, several virtual machines are restarted on the remaining hosts in the cluster. What is the most likely reason for this behavior?
- A
The Admission Control policy is disabled, and the cluster is overcommitted.
- B
Host Monitoring is disabled in the HA settings.
- C
The vSphere Distributed Resource Scheduler (DRS) is not enabled.
- D
The VM Restart Priority settings are set to 'Disabled' for the affected virtual machines.
Show answer and explanation
Correct answer: A
Explanation
vSphere High Availability (HA) ensures virtual machines are restarted on other hosts in the cluster when a host fails or is intentionally powered off. If Admission Control is disabled, the cluster does not reserve resources for failover, which can lead to resource contention and virtual machines being restarted on other hosts. The described behavior aligns with this scenario, making the first option correct.
- A. Correct.
When Admission Control is disabled, the HA cluster does not reserve resources for failover capacity. This can lead to overcommitment, causing virtual machines to restart as they attempt to allocate resources on other hosts.
- B. Incorrect.
If Host Monitoring is disabled, HA would not detect the host failure or planned shutdown, and virtual machines would not restart automatically on other hosts.
- C. Incorrect.
While DRS helps balance workloads across the cluster, it does not directly impact HA behavior during a host failure or shutdown.
- D. Incorrect.
If VM Restart Priority is set to 'Disabled,' the virtual machines would not restart at all, contradicting the scenario described.
