2V0-41.24 Question 304
Single answerA network engineer is tasked with configuring a Tier-1 gateway in an NSX-T environment to support North-South traffic for a workload segment. The engineer notices that the workload segment's traffic cannot reach external networks. After reviewing the configuration, the engineer decides to validate the Tier-1 gateway settings. Which configuration step is necessary to enable external connectivity through the Tier-1 gateway?
- A
Attach the Tier-1 gateway to a Tier-0 gateway
- B
Enable Distributed Firewall (DFW) on the Tier-1 gateway
- C
Add a static route on the Tier-1 gateway pointing to the external network
- D
Configure NAT rules on the Tier-1 gateway
Show answer and explanation
Correct answer: A
Explanation
To enable external connectivity for North-South traffic, the Tier-1 gateway must be attached to a Tier-0 gateway. The Tier-0 gateway serves as the uplink to the physical network, allowing traffic to flow to and from external networks. Without this connection, the Tier-1 gateway cannot route traffic externally, regardless of other configurations such as NAT or static routes.
- A. Correct.
Attaching the Tier-1 gateway to a Tier-0 gateway is necessary for enabling North-South connectivity. The Tier-0 gateway acts as the uplink to the physical network.
- B. Incorrect.
Enabling Distributed Firewall (DFW) on the Tier-1 gateway is unrelated to the issue of external connectivity. DFW is used for managing traffic security policies rather than routing traffic.
- C. Incorrect.
Adding a static route on the Tier-1 gateway is not required in this scenario because the Tier-1 gateway automatically propagates routes to the Tier-0 gateway when connected.
- D. Incorrect.
Configuring NAT rules on the Tier-1 gateway is optional and only required if you need to perform address translation. It does not directly enable external connectivity.
