CCDE: Cisco Certified Design Expert (Practical) — Question 161

Which two statements describe the hierarchical LAN design model? (Choose two.)

Answer options

• A. It is a well-understood architecture that provides scalability.
• B. It is the best design for modem data centers.
• C. Changes, upgrades, and new services can be introduced in a controlled and staged manner.
• D. It is the most optimal design but is highly complex.
• E. It provides a simplified design.

Correct answer: A, C

Explanation

The correct answers are A and C because the hierarchical LAN design model is known for its scalability and allows for controlled changes and upgrades. Options B, D, and E are incorrect as they misrepresent the model's purpose or characteristics; it is not specifically the best for modern data centers, not highly complex, and does not primarily focus on simplification.
