A network engineer is evaluating an architecture that utilizes VSS for the data center module. Which two advantages of using VSS technology are true?

Question

Options

• AIt removes the need for Hot Standby Router Protocol
• BIt removes the need to configure redundant switches with identical policies.
• CEach switch has a separate control plane
• DIt is capable of supporting live migration of virtual machines as they move from one physical
• EIt adds arbitrary forwarding topologies on top of a fixed routed underlay topology.

• A

• C

• E

Explanation

VSS (Virtual Switching System) logically merges two physical Cisco Catalyst switches into a single virtual switch with one unified control plane and one management interface. This architecture provides two key advantages: (A) HSRP is no longer needed because both physical switches present as a single Layer 3 gateway - there is no active/standby relationship, just one logical device with full active-active forwarding; (B) configuration and policy only need to be applied once to the VSS domain instead of being duplicated and kept synchronized across two separate switches. Option C is false - VSS uses a single shared control plane, which is a core benefit. Option D describes VM live migration capabilities related to data center fabric (vPC/VXLAN). Option E describes overlay networking technologies, not VSS.
