VCP-VCF Administrator 2024 Question 310
Select 3A VMware Cloud Foundation administrator observes high latency and degraded performance in a vSAN cluster. Upon investigation, the administrator notices that one of the hosts in the cluster has network-related issues. Which of the following steps should the administrator take to diagnose and resolve the issue?
- A
Verify the vSAN network configuration and ensure all vSAN VMkernel adapters are correctly tagged.
- B
Check the physical NICs on the affected host for link failures or errors.
- C
Increase the vSAN object replication factor to improve data availability.
- D
Run the vSAN Health Check to identify potential network misconfigurations.
- E
Reboot the affected host to resolve the network issue.
Show answer and explanation
Correct answers: A, B, D
Explanation
To diagnose and resolve vSAN network-related issues, it is important to verify the VMkernel network configuration, inspect physical NICs for errors, and run the vSAN Health Check to identify potential misconfigurations. These steps help ensure that the underlying problem is identified and addressed properly. Simply rebooting the host or making unrelated changes (like increasing the replication factor) will not resolve the network issue.
- A. Correct.
Verifying the vSAN network configuration ensures that the VMkernel adapters are properly configured for vSAN traffic, which is critical for performance.
- B. Correct.
Checking the physical NICs helps identify if there are any hardware-related issues such as link failures or excessive errors causing the network problem.
- C. Incorrect.
Increasing the vSAN object replication factor does not resolve network-related issues and may further strain the cluster’s resources.
- D. Correct.
Running the vSAN Health Check can help pinpoint any configuration or network-related issues, making it a recommended diagnostic step.
- E. Incorrect.
Rebooting the host without addressing the root cause of the network issue is not a recommended approach and may not resolve the problem.
