VCP-VMC 2024 Question 211
Single answerA VMware Cloud Administrator is troubleshooting a storage issue where virtual machines (VMs) are experiencing intermittent performance degradation. Upon investigation, the administrator notices high latency in the vSphere Client on a specific datastore. What should the administrator check first to identify the root cause?
- A
Check the storage array for hardware or performance issues.
- B
Verify if the datastore is running out of free space.
- C
Inspect the VMkernel logs for storage-related errors.
- D
Increase the datastore's size to handle higher workloads.
Show answer and explanation
Correct answer: A
Explanation
When troubleshooting high datastore latency, the first step is to verify the health and performance of the underlying storage array. This will help identify hardware or configuration issues causing the latency. Other steps, such as reviewing logs or checking free space, are important but secondary.
- A. Correct.
Correct. High latency on a datastore often indicates underlying issues with the storage array, such as hardware faults, overloaded controllers, or backend bottlenecks. This should be the first area to investigate.
- B. Incorrect.
Incorrect. While low free space can cause performance degradation, it does not directly explain high latency unless combined with other issues. This is not the first step to check.
- C. Incorrect.
Incorrect. VMkernel logs can provide valuable insights but reviewing them is typically a secondary step after verifying the storage array's health.
- D. Incorrect.
Incorrect. Increasing datastore size does not address the root cause of high latency. This action is only relevant if the issue is related to capacity, which is not evident here.
