VCP-VMC 2024 Question 188
Select 3A VMware Cloud Administrator is troubleshooting a workload issue where a VM is experiencing intermittent network connectivity in a VMware Cloud on AWS environment. Upon investigation, the administrator notices packet loss when pinging the default gateway of the SDDC and observes high CPU usage on the NSX edge appliance. What steps should the administrator take to resolve this issue?
- A
Verify the NSX edge appliance size and scale based on workload requirements.
- B
Increase the allocated memory for the NSX edge appliance using the VMware Cloud Console.
- C
Check for overlapping IP subnets between the on-premises network and the SDDC.
- D
Restart the affected VM to ensure it re-registers with the NSX edge appliance.
- E
Review the routing configuration and ensure there are no asymmetric routing issues.
Show answer and explanation
Correct answers: A, C, E
Explanation
The intermittent network connectivity and high CPU usage on the NSX edge appliance suggest a potential resource bottleneck or routing misconfiguration. Verifying the edge appliance's size and scale ensures it can handle the workload traffic. Overlapping subnets and asymmetric routing are common causes of network issues in hybrid environments. Restarting a VM or attempting to manually adjust NSX edge resources are not valid solutions in this scenario due to the managed nature of VMware Cloud on AWS.
- A. Correct.
The NSX edge appliance size might not be sufficient to handle the workload traffic. Verifying its size and scale is a critical first step in diagnosing high CPU usage.
- B. Incorrect.
While increasing memory might theoretically help in some cases, this option is not valid as NSX edge appliance resources in VMware Cloud on AWS are managed by VMware and cannot be manually adjusted.
- C. Correct.
Overlapping IP subnets can cause routing conflicts and packet loss. This is a common misconfiguration that must be resolved in hybrid cloud deployments.
- D. Incorrect.
Restarting the VM can address certain network issues but is unlikely to resolve the root cause of high CPU usage on the NSX edge or packet loss.
- E. Correct.
Asymmetric routing can lead to packet loss or intermittent connectivity. Reviewing and correcting routing configurations is an essential step during troubleshooting.
