2V0-41.24 Question 115
Select 3An organization has deployed NSX-T Data Center with both Tier-0 and Tier-1 Gateways. The network administrator wants to configure routing between the organization's on-premises data center and workloads hosted in the NSX-T environment. Which of the following statements about Tier-0 and Tier-1 Gateways are correct?
- A
Tier-0 Gateways are responsible for establishing north-south connectivity with physical routers.
- B
Tier-1 Gateways can directly establish BGP sessions with physical routers.
- C
Tier-1 Gateways require a Service Router (SR) for stateful services such as NAT.
- D
Tier-0 Gateways provide routing between Tier-1 Gateways and external networks.
- E
Tier-1 Gateways are responsible for east-west traffic between workloads within the NSX-T Data Center.
Show answer and explanation
Correct answers: A, C, D
Explanation
Tier-0 Gateways are designed to handle north-south traffic and connect the NSX-T environment to external physical networks, including establishing BGP sessions. Tier-1 Gateways are used to route traffic within the NSX-T environment and require a Service Router to provide stateful services. While Tier-1 Gateways cannot connect directly to physical routers, they can route traffic through a Tier-0 Gateway, which handles external connectivity. East-west traffic is managed at the distributed level by the data plane, not specifically by Tier-1 Gateways.
- A. Correct.
Correct. Tier-0 Gateways connect the NSX-T environment to external physical networks, providing north-south connectivity.
- B. Incorrect.
Incorrect. Tier-1 Gateways cannot directly establish BGP sessions with physical routers. BGP sessions are established by Tier-0 Gateways.
- C. Correct.
Correct. Tier-1 Gateways require a Service Router (SR) to handle stateful services like NAT, DHCP, or load balancing.
- D. Correct.
Correct. Tier-0 Gateways are responsible for routing traffic between Tier-1 Gateways and external networks.
- E. Incorrect.
Incorrect. East-west traffic between workloads is handled at the distributed data plane level, not by Tier-1 Gateways.
