2V0-41.24 Question 343
Select 3You are configuring a Tier-0 Gateway in an NSX-T Data Center environment. After deployment, you notice that external connectivity is not functioning as expected. Using the network topology feature in NSX Manager, which steps should you take to validate the Tier-0 Gateway configuration?
- A
Verify that the Tier-0 Gateway is connected to at least one uplink interface with an IP address.
- B
Check if the Tier-0 Gateway has been assigned a valid BGP configuration and is peering with external routers.
- C
Ensure that a Tier-1 Gateway is directly connected to the Tier-0 Gateway in the topology view.
- D
Validate that the external interface of the Tier-0 Gateway is advertised in the routing table.
- E
Confirm that the Edge Node hosting the Tier-0 Gateway is in a healthy state.
Show answer and explanation
Correct answers: A, B, E
Explanation
To validate the Tier-0 Gateway configuration using the network topology feature in NSX Manager, you must ensure that the gateway has an uplink interface with a valid IP address, verify the BGP configuration and peering status, and confirm the health of the Edge Node hosting the gateway. These are critical steps for diagnosing and resolving external connectivity issues related to the Tier-0 Gateway.
- A. Correct.
The Tier-0 Gateway must have at least one uplink interface with an IP address to establish external connectivity. This can be validated in the network topology view.
- B. Correct.
BGP is commonly used for dynamic routing in NSX-T environments. Verifying the BGP configuration and peering status is crucial for external connectivity.
- C. Incorrect.
While a Tier-1 Gateway may be connected to the Tier-0 Gateway in many environments, this is not a requirement for external connectivity validation.
- D. Incorrect.
The external interface being advertised in the routing table is verified through routing configuration, not directly through the topology view.
- E. Correct.
The Edge Node hosting the Tier-0 Gateway must be in a healthy state for the Gateway to function properly. This can be validated in the topology view by checking the node's status.
