2V0-41.24 Question 377
Single answerAn organization has deployed a VMware NSX-T Data Center environment with a Tier-0 Gateway configured to use NAT for outbound traffic. The administrator needs to redistribute the NAT routes into the external BGP route table. Which configuration step must the administrator perform to achieve this?
- A
Enable route redistribution for NAT on the Tier-0 Gateway and configure a BGP neighbor.
- B
Configure NAT rules on the Tier-1 Gateway and enable route redistribution for NAT.
- C
Enable route redistribution for NAT on the Tier-0 Gateway and configure a redistribution policy.
- D
Enable route aggregation on the Tier-0 Gateway and configure a redistribution policy.
Show answer and explanation
Correct answer: C
Explanation
In NSX-T, NAT route redistribution allows NAT rules configured on the Tier-0 Gateway to be advertised to external routers via routing protocols like BGP or OSPF. To achieve this, the administrator must enable route redistribution for NAT on the Tier-0 Gateway and configure a redistribution policy to specify which NAT routes will be advertised. Without the redistribution policy, the NAT routes cannot be propagated to external networks.
- A. Incorrect.
Correct. To redistribute NAT routes into the external routing protocol (e.g., BGP), the administrator must enable route redistribution for NAT on the Tier-0 Gateway and create a redistribution policy to define which NAT routes will be advertised.
- B. Incorrect.
Incorrect. NAT rules are not configured on the Tier-1 Gateway for this purpose. NAT route redistribution is relevant to the Tier-0 Gateway, which handles external routing protocols.
- C. Correct.
Incorrect. While enabling route redistribution for NAT on the Tier-0 Gateway is necessary, configuring a BGP neighbor is not sufficient to redistribute NAT routes into the external routing table. A redistribution policy is required.
- D. Incorrect.
Incorrect. Route aggregation is not related to NAT route redistribution. A redistribution policy specifically for NAT is needed to achieve this.
