2V0-41.24 Question 322
Single answerAn organization is deploying a new NSX-T environment and needs to create a Tier-0 gateway to enable north-south routing. The network administrator is configuring the Tier-0 gateway but encounters connectivity issues. Which critical step must be performed to ensure the Tier-0 gateway functions properly?
- A
Configure an external interface on the Tier-0 gateway and attach it to an uplink segment.
- B
Enable DHCP on the Tier-0 gateway to assign IP addresses to connected devices.
- C
Assign a default gateway to the Tier-0 gateway.
- D
Attach the Tier-0 gateway to a Tier-1 gateway.
Show answer and explanation
Correct answer: A
Explanation
To enable north-south routing in an NSX-T environment, a Tier-0 gateway must have an external interface configured and attached to an uplink segment. This configuration allows the Tier-0 gateway to route traffic between the NSX-T environment and the physical network. Without this step, external connectivity will not work, leading to connectivity issues.
- A. Correct.
Correct: Configuring an external interface on the Tier-0 gateway and attaching it to an uplink segment is essential for enabling north-south traffic and establishing connectivity with external networks.
- B. Incorrect.
Incorrect: Enabling DHCP on a Tier-0 gateway is not a requirement for connectivity. DHCP functionality is typically handled at the Tier-1 gateway or other network components.
- C. Incorrect.
Incorrect: Assigning a default gateway to a Tier-0 gateway is not a configuration step in NSX-T. The Tier-0 gateway itself acts as a router for north-south traffic.
- D. Incorrect.
Incorrect: Attaching a Tier-0 gateway to a Tier-1 gateway is not mandatory for external connectivity. A Tier-0 gateway can function independently for routing north-south traffic.
