VCP-VCF Administrator 2024 Question 334
Select 3During a routine health check of your VMware Cloud Foundation environment, you notice that the Tier-0 gateway in your NSX Edge Cluster is reporting high CPU usage. What steps can you take to identify and resolve the issue?
- A
Verify the number of active services configured on the Tier-0 gateway, such as NAT or load balancing, as these can increase resource utilization.
- B
Check the connectivity status between the Tier-0 and Tier-1 routers to ensure proper route propagation.
- C
Scale up the NSX Edge node resources in the cluster without investigating the root cause.
- D
Review the traffic flow and routing configuration to identify whether asymmetrical routing is causing increased processing overhead.
- E
Recreate the Tier-0 gateway without taking a backup of the current configuration to reset its state.
Show answer and explanation
Correct answers: A, B, D
Explanation
When diagnosing high CPU usage on an NSX Edge Cluster Tier-0 gateway, you should focus on identifying potential configuration or connectivity issues, such as services running on the gateway, route propagation, or traffic flow patterns. Investigating these areas provides insight into the root cause of the issue, whereas actions like scaling resources or recreating the gateway without backup can lead to temporary fixes or additional problems.
- A. Correct.
Verifying the number of active services on the Tier-0 gateway is essential as services like NAT and load balancing can significantly increase resource utilization on the Edge node.
- B. Correct.
Checking the connectivity between Tier-0 and Tier-1 routers helps ensure proper route propagation. Issues here can lead to misroutes or excessive resource usage.
- C. Incorrect.
Scaling up resources on the NSX Edge nodes without investigating the root cause may temporarily alleviate symptoms but does not address the underlying issue.
- D. Correct.
Reviewing the traffic flow and routing configuration can help identify issues like asymmetrical routing, which can increase processing overhead on the Tier-0 gateway.
- E. Incorrect.
Recreating the Tier-0 gateway without backup is not a recommended troubleshooting step. It risks data loss and misconfiguration without solving the actual problem.
