2V0-41.24 Question 74
Select 3An administrator is deploying a VMware NSX-T environment and is configuring logical switches. They want to understand how the control plane interacts with the data plane to ensure logical switching operates correctly. Which of the following functions best describe the role of the control plane in logical switching?
- A
Distributes logical networking state to hypervisors and NSX-T transport nodes.
- B
Handles packet forwarding and ensures data path availability.
- C
Populates forwarding tables with information about logical switch topology and VM MAC addresses.
- D
Ensures communication between NSX Managers and the physical network.
- E
Manages communication between compute nodes and updates state changes for logical switches.
Show answer and explanation
Correct answers: A, C, E
Explanation
The control plane in logical switching is responsible for distributing logical networking state, maintaining topology and forwarding information, and ensuring communication and synchronization between compute nodes. It does not handle packet forwarding (data plane responsibility) or direct communication with physical network devices (management plane responsibility).
- A. Correct.
Correct. The control plane disseminates logical networking state, such as switch topology and MAC address information, to transport nodes.
- B. Incorrect.
Incorrect. Packet forwarding is a function of the data plane, not the control plane.
- C. Correct.
Correct. The control plane ensures forwarding tables are populated with necessary information about logical switches and VM MAC addresses.
- D. Incorrect.
Incorrect. Communication between NSX Managers and the physical network is not a control plane responsibility; this is typically handled by the management plane.
- E. Correct.
Correct. The control plane manages communication between compute nodes and keeps their logical switch state updated, ensuring consistent network operations.
