CCDE: Cisco Certified Design Expert (Practical) — Question 57

What is a disadvantage of the traditional three-tier architecture model when east west traffic between different pods must go through the distribution and core layers?

Answer options

• A. low bandwidth
• B. security
• C. scalability
• D. high latency

Correct answer: D

Explanation

The correct answer is D, high latency, because routing traffic through multiple layers can introduce delays, particularly for east-west traffic. Options A (low bandwidth), B (security), and C (scalability) do not directly relate to the latency issues caused by the architecture's design in handling pod communications.
