Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 58

Which two characteristics apply to Cisco Catalyst 6500 Series Switch supervisor redundancy using NSF? (Choose two.)

Answer options

• A. supported by RIPv2, OSPF, IS-IS, and EIGRP
• B. uses the FIB table
• C. supports IPv4 and IPv6 multicast
• D. prevents route flapping D

Correct answer:

Explanation

The correct answers are A and B because Cisco Catalyst 6500 Series Switch supervisor redundancy with NSF is compatible with routing protocols like RIPv2, OSPF, IS-IS, and EIGRP, and it uses the FIB table to maintain forwarding information. Options C and D are incorrect as while IPv4 and IPv6 multicast support is a feature, it is not a direct characteristic of NSF redundancy, and preventing route flapping is not a specific function of the NSF mechanism.
