2V0-41.24 Question 39
Select 3An organization is troubleshooting network connectivity issues in their NSX-T environment. During the investigation, they identify that packets are being dropped between two VMs on the same host. The network administrator suspects an issue in the data plane. Which of the following steps should the administrator take to narrow down the root cause?
- A
Verify that the VMs are connected to the correct logical switch.
- B
Check the status of the Transport Node and ensure the N-VDS/VDS is operational.
- C
Inspect the firewall rules configured at the Distributed Firewall (DFW) level.
- D
Ensure the Edge Node is properly configured for VLAN tagging.
- E
Analyze the Geneve tunnel status between the two VMs.
Show answer and explanation
Correct answers: A, B, C
Explanation
In NSX-T, the data plane is responsible for forwarding traffic between endpoints. When investigating packet drops between two VMs on the same host, it is essential to verify the logical switch connectivity, Transport Node status, and Distributed Firewall rules, as these are all part of the data plane functionality. Edge Node configuration and Geneve tunnels are not relevant in this scenario as the communication is within the same host.
- A. Correct.
Correct. Ensuring that the VMs are connected to the correct logical switch is an important step to verify that the data plane path is correctly configured.
- B. Correct.
Correct. The Transport Node and the N-VDS/VDS on the host are critical components of the data plane. If they are not operational, this could lead to packet drops.
- C. Correct.
Correct. The Distributed Firewall is part of the data plane and can drop packets if firewall rules are misconfigured or applied incorrectly.
- D. Incorrect.
Incorrect. Edge Nodes are used for north-south traffic and VLAN tagging is not relevant for communication between two VMs on the same host.
- E. Incorrect.
Incorrect. Geneve tunnels are used for overlay traffic between hosts. Since the two VMs are on the same host, Geneve tunnels are not involved.
