2V0-41.24 Question 328
Single answerAn administrator is validating the Tier-0 gateway configuration in an NSX deployment using the network topology view. The topology shows that the Tier-0 gateway is connected to multiple Tier-1 gateways, but traffic between the connected segments is not flowing as expected. What action should the administrator take to resolve the issue?
- A
Ensure that route redistribution is configured between the Tier-0 and Tier-1 gateways.
- B
Verify that the Tier-0 gateway is connected to an Edge Node for north-south traffic.
- C
Check if the Tier-1 gateways have DHCP relay configured for the connected segments.
- D
Confirm that the Tier-0 gateway has BGP enabled and peering with an external router.
Show answer and explanation
Correct answer: A
Explanation
In an NSX deployment, for traffic to flow between Tier-0 and Tier-1 gateways, route redistribution must be configured to share routes between these entities. The network topology view can help identify misconfigurations, such as missing route redistribution, which would block traffic flow despite the connectivity shown in the topology.
- A. Correct.
Route redistribution is crucial for connectivity between Tier-0 and Tier-1 gateways. Without it, the Tier-0 gateway will not propagate routes to the Tier-1 gateways and vice versa, leading to traffic flow issues.
- B. Incorrect.
While the Tier-0 gateway needs to connect to an Edge Node for north-south traffic, this does not impact connectivity between Tier-0 and Tier-1 gateways, which is the issue described in the scenario.
- C. Incorrect.
DHCP relay is used to provide IP addressing for segments but does not impact route propagation or connectivity between Tier-0 and Tier-1 gateways.
- D. Incorrect.
BGP configuration is required for external routing, but it does not directly impact the connectivity between Tier-0 and Tier-1 gateways within the NSX environment.
