CCDE: Cisco Certified Design Expert (Practical) — Question 253

Over the years, many solutions have been developed to limit control plane state, which reduces the scope or the speed of control plane information propagation. Which solution removes more specific information about a particular destination as topological distance is covered in the network?

Answer options

• A. aggregation
• B. summarization
• C. back-off timers
• D. layering

Correct answer: B

Explanation

The correct answer is B, summarization, as it condenses detailed routing information into broader summaries, allowing for efficient data propagation over distance. Options A, aggregation, and C, back-off timers, do not specifically address the removal of detailed destination information, while D, layering, refers to the architectural structure rather than the control plane state management.
