2V0-41.24 Question 329
Select 3You are tasked with validating the configuration of a Tier-0 gateway in an NSX environment. Upon reviewing the network topology, you observe that the Tier-0 gateway has been configured in 'Active-Active' mode. However, north-south connectivity is failing. Which of the following actions should you take to validate and troubleshoot the Tier-0 gateway configuration?
- A
Verify if the external BGP neighbors are established and exchanging routes.
- B
Check whether the Tier-0 gateway is properly attached to the Tier-1 gateway.
- C
Ensure the Tier-0 gateway is configured with a default static route pointing to the physical router.
- D
Validate that the Tier-0 gateway interfaces are mapped to the correct uplink profiles.
- E
Review the firewall rules to confirm that traffic between the Tier-0 gateway and the external network is not being blocked.
Show answer and explanation
Correct answers: A, D, E
Explanation
In an 'Active-Active' Tier-0 gateway configuration, north-south connectivity relies on proper dynamic routing, correct uplink interface mapping, and no firewall restrictions. Verifying BGP neighbor status, ensuring interfaces are mapped to the correct uplink profiles, and confirming firewall rules are essential steps to validate and troubleshoot the Tier-0 gateway configuration.
- A. Correct.
Verifying if the external BGP neighbors are established and exchanging routes is crucial in an Active-Active setup to ensure proper routing and north-south connectivity.
- B. Incorrect.
While Tier-0 and Tier-1 attachment is important, this is not directly related to troubleshooting north-south connectivity issues in this scenario.
- C. Incorrect.
A default static route is not required when dynamic routing protocols like BGP are in use, especially in an 'Active-Active' configuration.
- D. Correct.
Validating the correct mapping of Tier-0 gateway interfaces to uplink profiles ensures that the interfaces are properly connected to the physical network.
- E. Correct.
Checking the firewall rules helps ensure that traffic is not inadvertently blocked between the Tier-0 gateway and the external network.
