Designing Cisco Network Service Architectures (ARCH, legacy) — Question 71

Which two of these are correct regarding the recommended practice for distribution layer design? (Choose two.)

Answer options

• A. use a redundant link to the core
• B. use a Layer 2 link between distribution switches
• C. never use a redundant link to the core because of convergence issues
• D. use a Layer 3 link between distribution switches with route summarization
• E. use a Layer 3 link between distribution switches without route summarization

Correct answer: A, D

Explanation

The correct answers, A and D, emphasize the importance of resiliency and efficient routing in distribution layer design. Using a redundant link to the core (A) ensures high availability, while a Layer 3 link with route summarization (D) improves routing efficiency. Options B, C, and E are incorrect as they either compromise redundancy or fail to utilize route summarization effectively.
