1. Understanding NSX-T Data Plane Functionality
* The data plane is responsible for forwarding packets between workloads within the NSX environment.
* It operates at the host level (ESXi/KVM transport nodes), using the N-VDS or vSphere VDS for network traffic forwarding.
2. Why "Manages Data Traffic" is the Correct Answer (B)
* The data plane moves packets based on the forwarding decisions made by the control plane.
* NSX uses the Geneve encapsulation protocol for overlay traffic.
* Distributed Firewall (DFW) operates in the data plane to enforce security policies.
3. Why Other Options are Incorrect
* (A - Controls Behavior):
* This is the role of the Control Plane, not the Data Plane.
* (C - Provides APIs):
* APIs are part of the Management Plane.
* (D - Handles Configuration):
* Configuration is managed at the Control and Management Planes.
4. NSX-T Data Plane Design Considerations
* Ensure that Transport Zones and TEPs (Tunnel Endpoints) are correctly configured.
* Use DPDK-based acceleration for high-performance workloads.
* Monitor data plane performance metrics using NSX Manager.
