ICND1: Interconnecting Cisco Networking Devices Part 1 (CCENT, legacy) — Question 25

Which forwarding technology stores destination addresses in the cache?

Answer options

• A. MPLS
• B. Cisco express forwarding
• C. Process switching
• D. Fast switching

Correct answer: B

Explanation

Cisco Express Forwarding (CEF) is the correct answer because it utilizes a forwarding information base (FIB) and adjacency table to store destination addresses in memory for quick access. In contrast, MPLS, Process Switching, and Fast Switching do not cache destination addresses in the same way, making them less efficient for rapid packet forwarding.
