2V0-41.24 Question 362
Select 3You are tasked with troubleshooting an application connectivity issue in a VMware NSX-T Data Center environment. The application is deployed across multiple virtual machines in different VRFs, and connectivity is established through static routes. During the investigation, you review the routing tables for each VRF. What should you validate to ensure proper routing between the VRFs?
- A
Ensure that the static routes in each VRF point to the correct next-hop IP addresses.
- B
Verify that the Route Target (RT) values are unique for each VRF.
- C
Check that the routing tables in each VRF have no overlapping IP address ranges.
- D
Confirm that the Tier-0 Gateway is advertising the routes between the VRFs.
- E
Ensure that the VRFs are associated with separate logical switches.
Show answer and explanation
Correct answers: A, C, D
Explanation
To ensure proper routing between VRFs, you must validate that static routes have correct next-hop IPs, check for overlapping IP ranges in the routing tables, and confirm that the Tier-0 Gateway is advertising the routes. These are core configurations that influence inter-VRF connectivity. Route Targets are not applicable in a static routing context, and logical switch associations are unrelated to routing table configurations.
- A. Correct.
Static routes must have the correct next-hop IP addresses for traffic to be forwarded properly between VRFs. Incorrect next-hop IPs will result in routing failures.
- B. Incorrect.
While Route Targets (RTs) are used in BGP configurations for route filtering and sharing, they are not directly relevant to static routing in VRFs.
- C. Correct.
Overlapping IP address ranges in the routing tables of different VRFs can cause unpredictable behavior and routing conflicts, so it is critical to validate this aspect.
- D. Correct.
The Tier-0 Gateway plays a key role in route advertisement between VRFs. If the routes are not being advertised correctly, communication between VRFs will fail.
- E. Incorrect.
Logical switches are not directly relevant to routing table configurations in VRFs. Routing is handled independently of the logical switch associations.
