VCP-VMC 2024 Question 190
Select 4A VMware Cloud on AWS environment is experiencing connectivity issues between the hosted VMware vSphere workloads and an on-premises data center. The administrator has verified that the AWS Direct Connect link is operational and configured correctly. Which of the following troubleshooting steps should be taken to identify the root cause of the issue?
- A
Verify the Firewall Rules in the VMware Cloud on AWS environment to ensure traffic between the SDDC and on-premises is allowed.
- B
Check the VMware NSX-T Edge routing table within the SDDC for incorrect or missing routes to the on-premises network.
- C
Run a Packet Capture from the on-premises data center to the SDDC to analyze traffic flow and detect potential packet drops.
- D
Validate that the VMware Cloud on AWS SDDC is using the default DHCP settings for the management network.
- E
Ensure the on-premises network devices are configured with the correct Autonomous System (AS) number for BGP peering.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
To troubleshoot connectivity between VMware Cloud on AWS and an on-premises data center, the administrator must systematically verify potential points of failure. Firewall rules need to allow traffic between the SDDC and on-premises, routing tables must include correct routes, and packet captures can provide insights into traffic flow issues. Additionally, proper BGP peering configuration is critical for ensuring routing works correctly. Validating DHCP settings for the management network, however, does not impact SDDC-to-on-premises connectivity.
- A. Correct.
Correct: Incorrect firewall rules can block traffic between the VMware Cloud on AWS SDDC and the on-premises data center, causing connectivity issues.
- B. Correct.
Correct: An incorrect or missing route in the NSX-T Edge routing table can prevent traffic from reaching the intended destination.
- C. Correct.
Correct: Packet captures are a key troubleshooting tool to identify issues such as packet drops, misconfigurations, or other communication problems.
- D. Incorrect.
Incorrect: The SDDC management network does not rely on default DHCP settings for connectivity to on-premises networks. This option is irrelevant to the scenario.
- E. Correct.
Correct: BGP peering issues, such as mismatched Autonomous System (AS) numbers, can disrupt routing between the on-premises and VMware Cloud on AWS environment.
