2V0-41.24 Question 250
Select 2An organization is deploying a VMware NSX environment with a requirement to stretch its network across multiple geographical locations. They plan to configure Tier-0 and Tier-1 gateways to support this stretched topology. Which of the following statements correctly describe supported configurations for Tier-0 and Tier-1 in a stretched topology?
- A
A Tier-0 gateway can operate in active-active mode in a stretched topology.
- B
A Tier-1 gateway must be deployed in active-standby mode in a stretched topology.
- C
A stretched Tier-0 gateway is only supported in active-standby mode.
- D
Tier-1 gateways can operate in active-active mode in a stretched topology.
- E
Both Tier-0 and Tier-1 gateways must be deployed in active-standby mode in a stretched topology.
Show answer and explanation
Correct answers: B, C
Explanation
In VMware NSX stretched topologies, Tier-0 gateways must operate in active-standby mode to ensure consistent routing and avoid asymmetric routing issues, while Tier-1 gateways must also be deployed in active-standby mode to maintain synchronization of stateful services like NAT and firewall. This configuration ensures high availability and consistency across the stretched environment.
- A. Incorrect.
Incorrect. A Tier-0 gateway in a stretched topology must be deployed in active-standby mode to ensure consistent routing and high availability across sites.
- B. Correct.
Correct. A Tier-1 gateway in a stretched topology must always operate in active-standby mode to ensure stateful services are synchronized across geographical locations.
- C. Correct.
Correct. A Tier-0 gateway in a stretched topology is supported only in active-standby mode to avoid asymmetric routing and to maintain consistency in the routing state.
- D. Incorrect.
Incorrect. Tier-1 gateways cannot operate in active-active mode in a stretched topology because it would lead to potential inconsistencies in stateful services like NAT and firewall.
- E. Incorrect.
Incorrect. While Tier-0 gateways are supported only in active-standby mode, Tier-1 gateways are also required to operate in active-standby mode. However, this option incorrectly suggests that both must be configured together in this mode.
