Designing Cisco Enterprise Networks (ENSLD) — Question 49

An engineer is designing an EIGRP network for a small branch office site where there is only one Layer 3 router. The engineer wants the router to advertise the local LAN network to remote EIGRP neighbors without sending any unnecessary multicast messages on the local LAN. Which action should the engineer take?

Answer options

• A. Use a static default route for this site instead of EIGRP
• B. Advertise the local LAN using the network command and the passive-interface feature
• C. Redistribute the local LAN network using the redistribute connected command
• D. Advertise the local LAN subnet as a stub network

Correct answer: B

Explanation

The correct answer is B because using the passive-interface feature allows the router to advertise the local LAN without sending multicast updates to the local segment. Option A does not utilize EIGRP, which is against the requirement. Option C could work but would still send unnecessary updates. Option D does not prevent multicast traffic on the local LAN.
