2V0-41.24 Question 451
Select 2An administrator is troubleshooting a VMware NSX-T Data Center deployment where newly created VMs are unable to communicate with devices outside their segment. Upon investigation, the administrator notices that the Tier-1 Logical Router is connected to the segment, but there is no connectivity to the Tier-0 Gateway. Which of the following actions should the administrator take to resolve the issue?
- A
Verify that the Tier-1 Logical Router is linked to the Tier-0 Gateway in the NSX-T Manager configuration.
- B
Check if the Edge Node Cluster assigned to the Tier-0 Gateway is operational and has sufficient resources.
- C
Ensure that the segment's Subnet IP Pool is properly configured and assigned to the VM network.
- D
Verify that the BGP configuration on the Tier-0 Gateway is correctly advertising the connected routes.
- E
Ensure that the Distributed Firewall (DFW) rules allow traffic between the segment and external devices.
Show answer and explanation
Correct answers: A, B
Explanation
To ensure connectivity between a Tier-1 Logical Router and external networks, it must be properly linked to a Tier-0 Gateway. Additionally, the Edge Node Cluster supporting the Tier-0 Gateway must be operational to handle north-south traffic. Other configurations, such as subnet IP pools or BGP, are unrelated to this specific issue and should be checked only if the primary configurations are correct.
- A. Correct.
The Tier-1 Logical Router must be explicitly linked to a Tier-0 Gateway to establish north-south connectivity. Without this linkage, traffic from the segment cannot reach external networks.
- B. Correct.
The Tier-0 Gateway's Edge Node Cluster must be operational and have sufficient resources to process traffic. If the Edge Nodes are not functioning properly, traffic to and from external networks will fail.
- C. Incorrect.
While the subnet IP pool configuration is important for assigning IPs to VMs, it is not directly related to the connectivity between the Tier-1 Logical Router and the Tier-0 Gateway.
- D. Incorrect.
BGP configuration on the Tier-0 Gateway is only relevant for dynamically advertising routes to external networks. It does not impact the internal connectivity between Tier-1 and Tier-0 components.
- E. Incorrect.
Distributed Firewall (DFW) rules focus on traffic filtering and security but are not directly responsible for the connectivity between the Tier-1 Logical Router and the Tier-0 Gateway.
