CCDE: Cisco Certified Design Expert (Practical) — Question 113

The Company XYZ network is experiencing attacks against their router. Which type of Control Plane Protection must be used on the router to protect all control plane IP traffic that is destined directly for one of the router interfaces?

Answer options

• A. Control Plane Protection transit subinterface
• B. Control Plane Protection host subinterface
• C. Control Plane Protection CEF-exception subinterface
• D. Control Plane Protection main interface

Correct answer: B

Explanation

The correct answer is B, as Control Plane Protection host subinterface is specifically designed to protect control plane traffic directed to the router's interfaces. The other options do not appropriately address the requirement for securing traffic aimed at the router's control plane from attacks.
