What is an advantage of using the Virtual Device Contexts feature in a data center environment?

Question

Options

• AThe same VLAN cannot be configured in separate Virtual Device Contexts.
• BThis feature provides fault domain separation.
• CSupervisor modules are shared between Virtual Device Contexts.
• DFabric modules are shared between Virtual Device Contexts.

• B
  93% (14)
• C
  7% (1)

Explanation

Virtual Device Contexts (VDCs), available on Cisco Nexus 7000 series switches, partition a single physical chassis into multiple logical switches, each with its own independent management plane, routing processes, and configuration. The key advantage is fault domain separation (B): a software crash, misconfiguration, or routing protocol failure in one VDC is isolated and does not impact other VDCs on the same hardware. Option A is incorrect - one benefit of VDCs is that the same VLAN can be reused independently in separate VDCs. Option C is incorrect because supervisor modules are shared physically but partitioned logically; a supervisor failure would affect all VDCs, which is a limitation, not an advantage. Option D is also a limitation rather than an advantage - shared fabric means a fabric failure impacts all VDCs.
