VCP-VCF Administrator 2024 Question 351
Select 3An administrator of a VMware Cloud Foundation environment notices a low Skyline vSAN Health Score and identifies a warning related to the 'Network Latency' health check. What action(s) should the administrator take to remediate this issue?
- A
Verify that all vSAN cluster hosts are using the same MTU settings across their VMkernel adapters.
- B
Check the vSAN VMkernel adapters for mismatched IP subnet configurations.
- C
Adjust the vSAN disk group storage policies to reduce the IOPS limit on the cluster.
- D
Review the physical network for potential bottlenecks, such as overutilized uplinks or misconfigured switches.
- E
Upgrade the vSAN cluster to the latest supported version of VMware ESXi.
Show answer and explanation
Correct answers: A, B, D
Explanation
The Skyline vSAN Health Score provides insights into the health and performance of a vSAN cluster. A low health score with a 'Network Latency' warning suggests issues related to the network configuration or performance. To remediate this, the administrator should verify consistent MTU settings, check for mismatched IP subnets, and review the physical network for bottlenecks or misconfigurations. These actions directly address the root causes of latency issues. Adjusting storage policies or upgrading ESXi may be useful in other contexts but are not relevant to resolving network-related problems.
- A. Correct.
Ensuring consistent MTU settings across VMkernel adapters is critical for vSAN performance and can help address network latency issues.
- B. Correct.
Mismatched IP subnet configurations can cause vSAN traffic to traverse external routers, leading to increased latency.
- C. Incorrect.
Adjusting storage policies does not directly address network latency issues and is therefore not relevant in this scenario.
- D. Correct.
Physical network bottlenecks, such as overutilized uplinks or misconfigured switches, can contribute to increased network latency impacting vSAN health.
- E. Incorrect.
Upgrading the vSAN cluster to the latest ESXi version is generally a best practice but is not directly related to resolving network latency issues.
