Which two benefits pf implementing multiple VDCs on a physical switch are true? (Choose two.)

The correct answer is C. It allows multiple logical switches to be created by using a single physical switch. E. Faults are isolated and contained within the specific VDC. This question asks to identify two true benefits of implementing multiple Virtual Device Contexts (VDCs) on a physical Cisco Nexus switch.

Why each option

This question asks to identify two true benefits of implementing multiple Virtual Device Contexts (VDCs) on a physical Cisco Nexus switch.

AIt simplifies the STP design.

Implementing multiple VDCs does not inherently simplify STP design, as each VDC runs its own STP instance, potentially adding to the complexity of managing STP across logical boundaries.

Ballows a physical port to be shared among multiple virtual Ethernet switches.

VDCs do not allow a physical port to be shared among multiple virtual Ethernet switches by assigning the same physical interface to different VDCs simultaneously; a physical interface is dedicated to a single VDC.

CIt allows multiple logical switches to be created by using a single physical switch.Correct

VDCs allow a single physical Cisco Nexus switch to be partitioned into multiple independent logical switches, each with its own control plane, data plane, and management plane. This provides administrative and resource separation.

DIt allows each VDC to run a different version of Cisco NX-OS.

All VDCs on a single physical Cisco Nexus switch must run the same version of Cisco NX-OS because they share the same underlying hardware and operating system image.

EFaults are isolated and contained within the specific VDC.Correct

A key benefit of VDCs is fault isolation; if a fault or configuration error occurs within one VDC, it is contained within that specific VDC and typically does not affect the operation of other VDCs on the same physical switch.
