Which description of a Cisco Nexus 1000V VSM module is true?

The VSM is the control plane, managing the data plane; the VEM is the component that actually runs over the data plane for forwarding traffic.

While the VSM communicates with VMware vCenter, its responsibilities extend beyond just communication, encompassing comprehensive control and configuration management for the virtual switch system.

The VSM provides the control plane for the Cisco Nexus 1000V system; the VEM (Virtual Ethernet Module) is the component that provides the data plane functionality.

The Cisco Nexus 1000V VSM (Virtual Supervisor Module) acts as the central control and management plane for the virtual distributed switch. It registers with VMware vCenter Server, manages the virtual network configuration, and pushes those configurations and policies down to the Virtual Ethernet Modules (VEMs) running on the ESXi hosts.
