VCP-VMC 2024 Question 171
Select 3You are managing a VMware Cloud on AWS environment with a 3-node cluster running several critical workloads. You need to perform a planned maintenance operation on one of the ESXi hosts in the cluster without impacting the running workloads. Which steps should you take to ensure a successful operation?
- A
Place the ESXi host in Maintenance Mode before the operation.
- B
Power off all virtual machines running on the ESXi host to prevent disruptions.
- C
Use the vSphere DRS (Distributed Resource Scheduler) to evacuate the virtual machines from the host.
- D
Verify that the cluster has sufficient capacity to accommodate the workloads from the host being maintained.
- E
Disable vSphere HA (High Availability) on the cluster before starting the maintenance.
Show answer and explanation
Correct answers: A, C, D
Explanation
To perform planned maintenance on an ESXi host in a VMware Cloud on AWS environment, you should place the host in Maintenance Mode, use vSphere DRS to intelligently evacuate virtual machines, and verify that the cluster has enough capacity to handle the workload redistribution. These steps ensure that workloads remain operational with minimal disruption. Disabling vSphere HA is unnecessary, and powering off virtual machines is not required when DRS is used.
- A. Correct.
Placing the ESXi host in Maintenance Mode ensures that all workloads are evacuated from the host before the maintenance operation begins. This is a recommended best practice.
- B. Incorrect.
Powering off all virtual machines is not necessary because vSphere DRS can automatically migrate workloads to other hosts in the cluster without downtime.
- C. Correct.
Using vSphere DRS to evacuate the virtual machines ensures that workloads are moved to other hosts intelligently, minimizing disruption.
- D. Correct.
Verifying cluster capacity is crucial to ensure that the remaining hosts in the cluster can accommodate the workloads being evacuated from the host under maintenance.
- E. Incorrect.
Disabling vSphere HA is not necessary for planned maintenance operations. It is designed to provide failover capabilities and does not need to be disabled.
