2V0-41.24 Question 38
Single answerA company is deploying VMware NSX to optimize its network infrastructure. During the deployment, the network administrator notices that VM-to-VM communication within the same ESXi host is not working as expected. After troubleshooting, the administrator identifies that the issue is related to the data plane. Based on this scenario, which component should the administrator verify to resolve the issue?
- A
The Distributed Virtual Switch (DVS) configuration
- B
The NSX Edge node routing table
- C
The status of the NSX Kernel Modules on the ESXi host
- D
The NSX Manager control plane connectivity
Show answer and explanation
Correct answer: C
Explanation
The NSX Kernel Modules are essential for the data plane operations in NSX, as they handle local packet forwarding and encapsulation. If VM-to-VM communication within the same ESXi host is failing, it is critical to verify the status of these modules to ensure data plane functionality. Other components like DVS, Edge routing, and NSX Manager are important but do not directly handle the data plane within a single ESXi host.
- A. Incorrect.
The Distributed Virtual Switch (DVS) configuration is important for overall network performance but is not directly related to the data plane function within a single ESXi host.
- B. Incorrect.
The NSX Edge node routing table manages routing between various subnets or external networks but does not impact VM-to-VM communication within the same host.
- C. Correct.
The NSX Kernel Modules on the ESXi host are responsible for the data plane functionality, including managing packet forwarding and encapsulation. If these modules are not functioning correctly, VM-to-VM communication on the same host can fail.
- D. Incorrect.
The NSX Manager control plane connectivity is used for managing configurations and state synchronization but does not directly affect the local data plane communication.
