2V0-41.24 Question 376
Single answerAn organization is using VMware NSX-T Data Center and has configured NAT on Tier-1 Gateways for external connectivity. The network administrator needs to ensure that routes for the NATed network are advertised to the Tier-0 Gateway for proper route distribution to the upstream physical routers. Which configuration step is required to achieve this?
- A
Enable route redistribution for NAT on the Tier-1 Gateway.
- B
Add NAT rules to the Tier-1 Gateway and enable redistribution on Tier-0 Gateway.
- C
Enable NAT route redistribution on the Tier-0 Gateway and configure route filters.
- D
Create a static route for the NATed network and redistribute it manually.
Show answer and explanation
Correct answer: C
Explanation
In VMware NSX-T, NAT route redistribution is configured at the Tier-0 Gateway level to ensure NATed networks are advertised to upstream routers. This configuration allows the Tier-0 Gateway to include the NATed network routes in its routing table and share them with the physical infrastructure. Route filters can be applied to fine-tune the routes being advertised.
- A. Incorrect.
Incorrect: Route redistribution for NAT needs to be enabled on the Tier-0 Gateway, not the Tier-1 Gateway.
- B. Incorrect.
Incorrect: While NAT rules are necessary on the Tier-1 Gateway, enabling redistribution must occur on the Tier-0 Gateway to advertise routes upstream.
- C. Correct.
Correct: NAT route redistribution must be explicitly enabled on the Tier-0 Gateway, and route filters may be used to control which routes are advertised to the upstream routers.
- D. Incorrect.
Incorrect: Static routes are not required when NAT route redistribution is properly configured; the system can dynamically advertise the NATed networks.
