2V0-41.24 Question 324
Select 3An organization is configuring a multi-tier architecture in an NSX-T environment. The Tier-1 gateway is intended to handle workloads for application VMs, and the Tier-0 gateway will provide external connectivity. Which steps must be taken to successfully connect the Tier-0 and Tier-1 gateways?
- A
Configure a Service Interface on the Tier-1 gateway and link it to the Tier-0 gateway.
- B
Set the Tier-1 gateway to 'Linked' mode and specify the Tier-0 gateway as the parent.
- C
Ensure that the Tier-0 gateway is configured to support a downlink interface for the Tier-1 gateway.
- D
Enable Route Advertisement on the Tier-1 gateway to advertise its subnets to the Tier-0 gateway.
- E
Configure the Tier-0 gateway to redistribute routes learned from the Tier-1 gateway to external networks.
Show answer and explanation
Correct answers: B, D, E
Explanation
To connect Tier-0 and Tier-1 gateways in an NSX-T environment, the Tier-1 gateway must be set to 'Linked' mode with the Tier-0 as its parent. Additionally, route advertisement must be enabled on the Tier-1 gateway to propagate its subnets to the Tier-0 gateway. The Tier-0 gateway must also redistribute these routes to external networks for proper communication between internal workloads and external entities.
- A. Incorrect.
Service Interfaces on Tier-1 gateways are used for specific use cases like connecting to VLANs, but they are not used to establish connections between Tier-0 and Tier-1 gateways.
- B. Correct.
This is correct. The Tier-1 gateway must be set to 'Linked' mode, and the Tier-0 gateway must be specified as the parent for them to connect properly.
- C. Incorrect.
While the Tier-0 gateway needs to provide connectivity to the Tier-1 gateway, this is achieved via the 'Linked' mode and not through manual configuration of a downlink interface.
- D. Correct.
This is correct. Route Advertisement must be enabled on the Tier-1 gateway to propagate its routes to the Tier-0 gateway.
- E. Correct.
This is correct. The Tier-0 gateway must be configured to redistribute routes learned from the Tier-1 gateway to external networks for full connectivity.
