2V0-41.24 Question 140
Select 3An organization is using VMware NSX-T Data Center to manage its network virtualization environment. A distributed logical router (DLR) is deployed with active and standby edge nodes. Due to a hardware failure, the active edge node becomes unavailable. What happens during the failover process, and what conditions must be met for the failover to be successful?
- A
The standby edge node automatically takes over routing responsibilities without manual intervention.
- B
The failover process requires the configuration of dynamic routing protocols on both active and standby edge nodes.
- C
The failover process will not occur unless the HA (High Availability) mode is enabled for the distributed logical router.
- D
Traffic is automatically rerouted to the standby edge node using the same IP and MAC addresses as the failed active edge node.
- E
The failover process requires manual intervention to reassign the logical router's responsibilities to the standby edge node.
Show answer and explanation
Correct answers: A, C, D
Explanation
In VMware NSX-T, the failover process for a distributed logical router ensures high availability and continuity of network services. When the active edge node fails, the standby edge node automatically takes over routing responsibilities without manual intervention. This is achieved by using the same IP and MAC addresses, preventing disruptions in traffic. However, for this process to function, HA must be enabled for the DLR. The automation of failover ensures minimal downtime and is a key feature of NSX-T's network virtualization capabilities.
- A. Correct.
Correct: In a VMware NSX-T environment, the standby edge node automatically takes over during a failover event, ensuring continuity without manual intervention.
- B. Incorrect.
Incorrect: While dynamic routing protocols are commonly used, they are not strictly required for the failover process to occur. Static routing can also be used, depending on the configuration.
- C. Correct.
Correct: The HA mode must be enabled for the distributed logical router to support an automatic failover process.
- D. Correct.
Correct: During a failover, the standby edge node uses the same IP and MAC addresses as the failed active edge node to ensure seamless traffic redirection without requiring changes to the network.
- E. Incorrect.
Incorrect: The failover process in NSX-T is automated and does not require manual intervention when HA is properly configured.
