2V0-41.24 Question 66
Single answerA network administrator is troubleshooting a connectivity issue in a VMware NSX-T Data Center environment. The logical switch is configured correctly, but virtual machines in the same logical switch are unable to communicate with each other. Upon investigation, the administrator finds that the transport nodes are configured in separate transport zones. Based on the interaction between logical switching components, what is the most likely cause of the issue?
- A
The Edge nodes are not participating in the same transport zone as the logical switch.
- B
The logical switch is not mapped to an appropriate VLAN segment.
- C
The transport nodes are part of different transport zones, preventing them from sharing the same logical switch.
- D
The Tier-1 Gateway has not been configured to allow east-west traffic.
Show answer and explanation
Correct answer: C
Explanation
Logical switches in NSX-T rely on transport zones to define their scope of operation. Transport nodes must be part of the same transport zone to participate in the same logical switch. If transport nodes are in separate transport zones, they cannot share the same logical switch, leading to communication failures between virtual machines. This scenario highlights the importance of aligning transport zones during logical switch configuration.
- A. Incorrect.
Incorrect. Edge nodes are primarily involved in north-south traffic routing and are not required for east-west communication within the same logical switch.
- B. Incorrect.
Incorrect. VLAN segments are not required for logical switches that operate in Overlay mode. This does not explain the issue in the given scenario.
- C. Correct.
Correct. Logical switches operate within the boundaries of a transport zone. If transport nodes are in different transport zones, they cannot participate in the same logical switch, which prevents virtual machines from communicating.
- D. Incorrect.
Incorrect. Tier-1 Gateways are involved in routing traffic across different segments or logical switches and are not required for communication within the same logical switch.
