Explanation

Virtual Device Contexts (VDC) is a Cisco Nexus feature that partitions a single physical switch into multiple logical devices, each with its own separate management plane, control plane, data plane, and administrative domain. This allows different divisions to manage their own virtual device independently without sharing access or visibility into other divisions - meeting the requirement for separate management control planes while minimizing physical hardware. VRF (A) provides routing table separation but does not create separate management planes. VSS (C) combines two physical switches into one logical unit, the opposite of what's needed. VLANs (D) provide L2 segmentation but share the same management plane. vPCs (E) are a link aggregation technology, not a management separation mechanism.
