An engineer has been asked to design a multitenant data center The core switches must be virtualized at the device level and must otter isolation on the control, data, and management planes. Which…

VRF (Virtual Routing and Forwarding) isolates routing table instances within a device but operates on the control and data planes only - it does not isolate the management plane or virtualize the device at the device level.

VDC is a Cisco Nexus feature that creates independent logical switch instances within one physical chassis, giving each tenant a separate control plane (independent routing processes and protocol state), data plane (isolated forwarding tables and hardware resources), and management plane (distinct CLI sessions, AAA, and SNMP contexts). This device-level virtualization provides the complete three-plane isolation required for a multitenant data center environment. No other listed technology provides all three planes of isolation within a single physical device.

VSS (Virtual Switching System) combines two physical switches into one logical switch for high availability, which is the opposite of creating multiple isolated virtual devices from one physical device.

VPC (Virtual Port Channel) enables redundant port channels across two physical Nexus switches for link redundancy but provides no device virtualization or tenant isolation.
