ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 112

Which two characteristics of a link-state routing protocol are true? (Choose two.)

Answer options

• A. It sends periodic updates.
• B. It has a higher CPU requirement than distance-vector protocols.
• C. It supports a hop-count limit.
• D. It receives updates on the multicast address.
• E. It receives updates on the broadcast address. BD

Correct answer:

Explanation

The correct answers are B and D. Link-state routing protocols do require more CPU resources than distance-vector protocols due to the need for maintaining a complete topology of the network. They also use multicast addresses to send updates efficiently to all routers in the network. Options A, C, and E are incorrect as link-state protocols do not send periodic updates, do not have a hop-count limit, and do not typically use broadcast addresses for updates.
