2V0-41.24 Question 344
Select 3An administrator is tasked with validating the Tier-0 gateway configuration in an NSX environment using the network topology tool. The administrator notices that the Tier-0 gateway is not advertising routes to the connected Tier-1 gateway. Which of the following steps should the administrator take to validate the Tier-0 gateway configuration and resolve the issue?
- A
Verify that the Tier-0 gateway is configured with a logical router port connected to the Tier-1 gateway.
- B
Check if route redistribution is enabled for the Tier-0 gateway.
- C
Ensure the Tier-0 gateway has a BGP neighbor configured with the physical router.
- D
Validate that the Tier-1 gateway is in an active state and connected to the Tier-0 gateway.
- E
Confirm that a default static route is configured on the Tier-0 gateway.
Show answer and explanation
Correct answers: A, B, D
Explanation
To validate the Tier-0 gateway configuration, it is critical to ensure that there is a logical connection between the Tier-0 and Tier-1 gateways, route redistribution is enabled, and the Tier-1 gateway is active and connected. These components ensure proper route advertisement within the NSX environment. BGP and static routes are not directly involved in the internal NSX route propagation between Tier-0 and Tier-1 gateways.
- A. Correct.
The Tier-0 gateway must have a logical router port connected to the Tier-1 gateway to facilitate communication and route advertisement.
- B. Correct.
Route redistribution is required to advertise Tier-0 routes to Tier-1 gateways. Without this setting, routes will not propagate.
- C. Incorrect.
While BGP is used for external routing, it is not directly related to the Tier-0 to Tier-1 route advertisement within NSX.
- D. Correct.
The Tier-1 gateway must be active and properly connected to the Tier-0 gateway for route advertisement to occur.
- E. Incorrect.
A default static route on the Tier-0 gateway is used for external connectivity but is not required for Tier-0 to Tier-1 route advertisement.
