The correct answer is A: dual supervisor modules. Dual supervisor modules and redundant power supplies are the primary physical hardware components that directly enable high availability on the Cisco Catalyst 6500 platform.

Question

Which two physical components can enable high availability on a Cisco 6500 device? (Choose two.)

Options

Adual supervisor modules
Bbundled Ethernet Interconnects
Cline modules with DFCs
Dredundant power supplies
EVSS interlink cables

Explanation

Dual supervisor modules and redundant power supplies are the primary physical hardware components that directly enable high availability on the Cisco Catalyst 6500 platform.

Common mistakes.

B. Bundled Ethernet interconnects are not a standard Cisco 6500 high-availability component; this term relates to link aggregation concepts and not a specific 6500 HA hardware feature.
C. Distributed Forwarding Cards (DFCs) on line modules enhance distributed hardware forwarding performance but are a performance scaling feature, not a high-availability component designed to provide redundancy during failures.
E. VSS interlink cables are required for a Virtual Switching System configuration that combines two 6500 chassis into a single logical switch, which is a specific design topology, not a standalone physical HA component of a single chassis.

Concept tested. Cisco Catalyst 6500 physical high-availability components
