2V0-41.24 Question 342
Select 3An organization has deployed NSX-T Data Center with a Tier-0 gateway configured to provide external connectivity for workloads. After verifying the network topology in the NSX Manager, the administrator notices that the Tier-0 gateway is in a 'Down' state. Which of the following steps should the administrator take to validate and resolve the Tier-0 gateway configuration?
- A
Ensure that the Tier-0 gateway is linked to a Transport Zone.
- B
Verify that the Tier-0 gateway has an active Edge Node assigned to it.
- C
Check if the Tier-0 gateway has an uplink with a valid IP address and VLAN configuration.
- D
Ensure that the Tier-0 gateway is directly connected to a Tier-1 gateway.
- E
Verify that the Tier-0 gateway has a route to the external network.
Show answer and explanation
Correct answers: B, C, E
Explanation
To validate and resolve a Tier-0 gateway in a 'Down' state, administrators should ensure the Tier-0 gateway has an active Edge Node assignment, valid uplink configuration (IP address and VLAN), and appropriate routes to the external network. These checks ensure that the Tier-0 gateway is fully operational and capable of providing connectivity as intended.
- A. Incorrect.
The Tier-0 gateway does not need to be directly linked to a Transport Zone. Instead, it uses the Transport Zones defined for Edge Nodes or uplinks. This is not a direct validation step for a Tier-0 gateway configuration.
- B. Correct.
An active Edge Node is required for the Tier-0 gateway to function properly. Without this, the Tier-0 gateway will not establish data path connectivity.
- C. Correct.
A valid uplink configuration, including IP address and VLAN settings, is essential for the Tier-0 gateway to establish external connectivity.
- D. Incorrect.
Tier-0 gateways are not required to be directly connected to Tier-1 gateways. They can operate independently to provide external connectivity.
- E. Correct.
Routes are necessary for the Tier-0 gateway to communicate with the external network. Without a route, even if the gateway is operational, it cannot reach the external network.
