CCNA: Cisco Certified Network Associate — Question 77

What is a characteristic of spine-and-leaf architecture?

Answer options

• A. Each link between leaf switches allows for higher bandwidth.
• B. It provides greater predictability on STP blocked ports.
• C. It provides variable latency.
• D. Each device is separated by the same number of hops.

Correct answer: D

Explanation

The correct answer is D because spine-and-leaf architecture is designed to ensure that all devices are equidistant in terms of hops, which enhances predictability and reduces latency. Option A is incorrect as it refers to bandwidth but does not specifically relate to the characteristic of equal hops. Options B and C are also not correct as they do not accurately describe the fundamental nature of spine-and-leaf architecture.
