CCIE Routing and Switching (legacy) — Question 3

Which two Cisco Express Forwarding tables are located in the data plane? (Choose two.)

Answer options

• A. the forwarding information base
• B. the label forwarding information base
• C. the IP routing table
• D. the label information table
• E. the adjacency table

Correct answer: A, B

Explanation

The correct answers are A and B, as the forwarding information base (FIB) and the label forwarding information base (LFIB) are both used in the data plane for fast packet forwarding. Options C, D, and E do not reside in the data plane; the IP routing table is part of the control plane, while the label information table and adjacency table are not directly involved in the data plane operations.
