Question

What is the primary benefit of implementing Virtual Device Contexts on Nexus hardware In a multi- tenant environment?

Options

Aresource isolation
Bsoftware partitioning
Cresource allocation
Dgranular monitoring

Explanation

Virtual Device Contexts (VDCs) allow a single physical Cisco Nexus switch to be partitioned into multiple independent logical devices. In a multi-tenant environment, the primary benefit is resource isolation - each tenant (or business unit) operates within its own VDC with a separate management plane, dedicated interfaces, independent routing tables, and isolated fault domains. A failure or misconfiguration in one VDC does not affect others. While VDCs do provide software partitioning and allow resource allocation, isolation is the core design goal in multi-tenancy: guaranteeing that tenants cannot interfere with each other's traffic, configuration, or operations.
