VCP-VMC 2024 Question 206
Select 3A VMware Cloud Administrator notices that a workload running on a virtual machine in VMware Cloud on AWS is experiencing intermittent performance issues. The VM is part of a stretched cluster, and storage latency is unusually high. Which of the following actions should the administrator take to troubleshoot and resolve the issue?
- A
Verify the storage policy assigned to the VM and ensure it is compliant.
- B
Check the network latency between availability zones in the stretched cluster.
- C
Migrate the VM to a host within the same availability zone using vMotion.
- D
Increase the VM's allocated CPU and memory resources to improve performance.
- E
Examine the health status of the vSAN datastore and check for any reported errors.
Show answer and explanation
Correct answers: A, B, E
Explanation
High storage latency in a VMware Cloud on AWS stretched cluster can result from storage policy misconfigurations, network latency between availability zones, or issues with the vSAN datastore. Verifying the storage policy, checking network latency, and examining the vSAN health are key steps in identifying and resolving the root cause of the issue.
- A. Correct.
Ensuring the storage policy is compliant can help identify misconfigurations or policy mismatches that may be contributing to high storage latency.
- B. Correct.
Network latency between availability zones in a stretched cluster can impact vSAN performance, especially if the data is being replicated across zones.
- C. Incorrect.
While migrating the VM using vMotion can temporarily alleviate performance issues, it does not address the root cause, which is related to storage latency.
- D. Incorrect.
Increasing CPU and memory resources may not resolve the underlying storage latency issue and could mislead the troubleshooting process.
- E. Correct.
Checking the health of the vSAN datastore and identifying any errors is essential to diagnosing and resolving storage-related performance issues.
