Designing for Cisco Internetwork Solutions (DESGN, legacy) — Question 16

Which WAN scenario might be appropriate for queuing solutions?

Answer options

• A. A newly implemented WAN connection has yet to demonstrate sufficient WAN statistics for congestion-level tracking.
• B. A WAN connection features consistent congestion problems, and data transfers often suffer.
• C. A WAN connection is rarely congested, and data transfers never suffer.
• D. A WAN connection features occasional periods of congestion, and data transfers have occasionally suffered as a result. D

Correct answer:

Explanation

The correct answer is D because queuing solutions are designed to manage congestion during periods when data flow is interrupted. Option B indicates consistent congestion, which may require a more permanent solution rather than just queuing. Options A and C are not suitable as they either lack enough data to support queuing or indicate no congestion at all.
