2V0-41.24 Question 454
Single answerAn administrator is troubleshooting a connectivity issue in an NSX-T Data Center environment. A newly created logical switch is not passing traffic between two VMs connected to it. The administrator has verified that the VMs are powered on and properly connected to the logical switch. What should the administrator check next to resolve the issue?
- A
Verify that the Transport Zone associated with the logical switch has the appropriate uplink configuration.
- B
Ensure that the Edge Node cluster is configured for high availability.
- C
Check whether the Tier-1 Gateway is linked to the logical switch.
- D
Verify that the MTU settings match between the physical network and the NSX-T environment.
Show answer and explanation
Correct answer: C
Explanation
In an NSX-T Data Center environment, logical switches provide Layer 2 connectivity. For traffic to flow beyond the logical switch or to connect to other NSX-T components, the logical switch must be linked to a Tier-1 Gateway. This ensures that the logical switch is properly integrated with the NSX-T control and data plane, enabling connectivity between the VMs.
- A. Incorrect.
The Transport Zone uplink configuration is related to the underlying transport network but does not directly impact the logical switch traffic between VMs, as they are connected at the overlay level.
- B. Incorrect.
Edge Node high availability is important for services like routing or NAT but does not affect L2 traffic between VMs connected to the same logical switch.
- C. Correct.
The logical switch must be linked to a Tier-1 Gateway to ensure proper Layer 3 connectivity and enable interconnectivity across different NSX-T components.
- D. Incorrect.
MTU mismatches can cause connectivity issues, but this would typically result in packet loss or degraded performance, not complete traffic failure between VMs on the same logical switch.
