2V0-41.24 Question 251
Select 2An organization is designing a VMware NSX-T Data Center environment to provide disaster recovery capabilities. They want to deploy a stretched topology for Tier-0 and Tier-1 gateways to ensure service continuity during a site failure. Which of the following are supported configurations for such a deployment?
- A
Tier-0 in active-active mode with Tier-1 in active-standby mode
- B
Tier-0 in active-standby mode with Tier-1 in active-standby mode
- C
Tier-0 in active-active mode with Tier-1 in active-active mode
- D
Tier-0 in active-standby mode with Tier-1 in active-active mode
- E
Tier-0 in active-active mode with Tier-1 in no HA mode
Show answer and explanation
Correct answers: A, B
Explanation
In a VMware NSX-T stretched topology, the supported configurations must ensure redundancy and service continuity across sites. Tier-0 gateways can be deployed in either active-active or active-standby mode, but the Tier-1 gateway must complement the Tier-0 configuration to avoid inconsistencies. Tier-1 in active-standby mode is required when Tier-0 is in active-active mode, while both Tier-0 and Tier-1 can be in active-standby mode in a disaster recovery scenario.
- A. Correct.
Correct: Tier-0 in active-active mode with Tier-1 in active-standby mode is a supported configuration for a stretched topology. This ensures that Tier-1 services have a primary location while still being resilient to failures.
- B. Correct.
Correct: Tier-0 in active-standby mode with Tier-1 in active-standby mode is a supported configuration for a stretched topology. This setup provides redundancy and is commonly used in disaster recovery scenarios.
- C. Incorrect.
Incorrect: Tier-0 in active-active mode with Tier-1 in active-active mode is not a supported configuration for a stretched topology, as it may lead to service inconsistencies across sites.
- D. Incorrect.
Incorrect: Tier-0 in active-standby mode with Tier-1 in active-active mode is not a supported configuration because Tier-1 in active-active mode conflicts with the HA requirements for stretched topologies.
- E. Incorrect.
Incorrect: Tier-0 in active-active mode with Tier-1 in no HA mode is not supported, as no HA mode does not align with the requirements for stretched topologies.
