2V0-41.24 Question 425
Select 4A network administrator is troubleshooting a connectivity issue in a VMware NSX-T Data Center environment. Virtual machines in a specific segment are unable to communicate with each other. Upon investigation, the administrator discovers that the Tier-1 Gateway is not forwarding traffic. Which of the following steps should the administrator take to resolve the issue?
- A
Verify that the Tier-1 Gateway is connected to the Tier-0 Gateway.
- B
Ensure that the Edge node associated with the Tier-1 Gateway is operational.
- C
Check if the segment is properly attached to the Tier-1 Gateway.
- D
Verify if Distributed Firewall rules are blocking the traffic.
- E
Restart the NSX Manager service.
Show answer and explanation
Correct answers: A, B, C, D
Explanation
When troubleshooting Tier-1 Gateway traffic issues, it is important to check the connectivity between the Tier-1 and Tier-0 Gateways, verify the operational state of associated Edge nodes, ensure proper segment attachment, and review Distributed Firewall rules. Restarting the NSX Manager is not a relevant action for this type of problem and should be avoided unless necessary for broader system issues.
- A. Correct.
If the Tier-1 Gateway is not connected to the Tier-0 Gateway, it cannot forward traffic to other segments or external networks.
- B. Correct.
The Edge node plays a crucial role in the forwarding of traffic for stateful services. If it is down, traffic may not flow as expected.
- C. Correct.
Segments must be correctly attached to the Tier-1 Gateway for traffic to be forwarded between VMs and other network resources.
- D. Correct.
Distributed Firewall rules could block communication between virtual machines if not properly configured. Reviewing and adjusting the rules may resolve the issue.
- E. Incorrect.
Restarting the NSX Manager service is not necessary for this scenario. It is typically a last resort for service-related issues and is not directly tied to Tier-1 Gateway functionality.
