2V0-41.24 Question 424
Select 3An administrator is troubleshooting a connectivity issue in a VMware NSX-T environment. A recently deployed virtual machine cannot communicate with external networks. The administrator has verified that the VM is connected to the correct segment and that the segment is associated with a Tier-1 Gateway. Which of the following steps should the administrator take to resolve the issue?
- A
Verify that the Tier-1 Gateway has a route to the external network via the Tier-0 Gateway.
- B
Ensure that the Edge Node is powered on and has no connectivity issues.
- C
Check the Distributed Firewall rules to ensure no rules are blocking traffic from the VM.
- D
Validate that the physical NICs on the ESXi host where the VM resides are properly configured and operational.
Show answer and explanation
Correct answers: A, B, C
Explanation
To troubleshoot connectivity issues for a VM in an NSX-T environment, administrators must ensure proper routing between Tier-1 and Tier-0 Gateways, confirm the Edge Node's functionality, and verify that the Distributed Firewall rules are not blocking traffic. While physical NICs are important, they are not specific to the issue described here, which focuses on logical networking components.
- A. Correct.
This is correct because the Tier-1 Gateway must have a routing relationship with the Tier-0 Gateway to ensure external connectivity for workloads connected to the segment.
- B. Correct.
This is correct because the Edge Node facilitates traffic between logical networks and external networks. If the Edge Node is down or has issues, the VM cannot communicate externally.
- C. Correct.
This is correct because a Distributed Firewall rule might block the VM’s traffic, preventing it from reaching the external network despite proper configurations elsewhere.
- D. Incorrect.
This is incorrect because while physical NICs are critical to overall ESXi host functionality, the VM’s inability to communicate externally in this scenario is more likely linked to logical networking configurations and not physical NIC issues.
