2V0-41.24 Question 119
Select 3You are tasked with configuring a Tier-0 gateway and a Tier-1 gateway in NSX-T to enable north-south and east-west traffic in a multi-tier topology. Which of the following steps should you perform to ensure proper connectivity and functionality?
- A
Configure an external uplink interface on the Tier-0 gateway and assign a public IP address.
- B
Establish a service interface on the Tier-1 gateway for external connectivity.
- C
Set up a router link port between the Tier-0 and Tier-1 gateways.
- D
Enable route advertisement on the Tier-0 gateway to advertise Tier-1 subnets to the physical network.
- E
Directly connect workloads to the Tier-0 gateway for east-west traffic.
Show answer and explanation
Correct answers: A, C, D
Explanation
To properly configure Tier-0 and Tier-1 gateways in NSX-T, you must ensure that the Tier-0 gateway has an external uplink interface for north-south connectivity, set up a router link port between the Tier-0 and Tier-1 gateways for communication, and enable route advertisement on the Tier-0 gateway to propagate routes to the physical network. Tier-1 gateways handle east-west traffic, and workloads are typically connected to Tier-1 segments rather than directly to the Tier-0 gateway.
- A. Correct.
Correct: Configuring an external uplink interface on the Tier-0 gateway with a public IP address is necessary to enable north-south traffic between the virtual network and the physical external network.
- B. Incorrect.
Incorrect: The Tier-1 gateway does not require a service interface for external connectivity. External connectivity is typically achieved through the Tier-0 gateway.
- C. Correct.
Correct: A router link port must be configured between the Tier-0 and Tier-1 gateways to enable communication and route propagation between the two tiers.
- D. Correct.
Correct: Route advertisement on the Tier-0 gateway is required to propagate the Tier-1 subnet routes to the physical network, ensuring north-south traffic can flow properly.
- E. Incorrect.
Incorrect: Workloads should not be directly connected to the Tier-0 gateway for east-west traffic. Workloads are typically connected to segments that are associated with the Tier-1 gateway, which handles east-west traffic.
