2V0-41.24 Question 310
Single answerAn administrator is configuring a new segment in an NSX-T Data Center environment. They want to connect this segment to an existing Tier-1 Gateway to ensure traffic can route to other segments and Tier-0 Gateway uplinks. Which action must the administrator take during this process?
- A
Assign a VLAN ID to the segment and link it to the Tier-1 Gateway.
- B
Set the Segment Type to 'Overlay' and assign the segment to the desired Tier-1 Gateway.
- C
Configure a Service Interface on the Tier-1 Gateway and attach the segment.
- D
Add the Segment to the Tier-1 Gateway's routing table.
Show answer and explanation
Correct answer: B
Explanation
To connect a segment to a Tier-1 Gateway in NSX-T, the segment must be created with the correct Segment Type (e.g., 'Overlay' for overlay transport zones) and explicitly assigned to the desired Tier-1 Gateway during configuration. This ensures that traffic can route between segments and upstream through the Tier-0 Gateway if needed.
- A. Incorrect.
Assigning a VLAN ID is only required for VLAN-backed segments, but the question does not mention using a VLAN-backed segment. Additionally, connecting a VLAN-backed segment to a Tier-1 Gateway requires more specific configurations, such as VLAN transport zones.
- B. Correct.
This is the correct answer. When creating a new segment in NSX-T, setting the Segment Type to 'Overlay' enables it to use the NSX-T overlay transport zone, and attaching it to the Tier-1 Gateway ensures proper connectivity and routing.
- C. Incorrect.
Service Interfaces are used for specific cases such as providing Layer 3 connectivity for VLAN subnets, not for connecting overlay segments to Tier-1 Gateways.
- D. Incorrect.
Segments are not directly added to a routing table. Routing occurs automatically when segments are connected to a Tier-1 Gateway, as long as appropriate routes exist.
