CCIE Routing and Switching (legacy) — Question 31

Which circumstance can cause packet loss due to a microburst?

Answer options

• A. slow convergence
• B. a blocked spanning-tree port
• C. process switching
• D. insufficient buffers

Correct answer: D

Explanation

The correct answer is D, as insufficient buffers can lead to packet loss during a microburst when there is a sudden spike in traffic that exceeds the available buffer capacity. Options A, B, and C do not directly relate to the immediate handling of burst traffic, making them less relevant in this context.
