Designing Cisco Enterprise Networks (ENSLD) — Question 298

Since installing a cisco TelePresence system, the company is experiencing other application having response issues when the system in use. As a result, the company asked an architect to recommend a QoS solution. The customer is currently using a CBWFQ policy to manage traffic on an internet connection with a speed of 100 Mbps. Which link-capacity limit must the architect choose for strict-priority for the real-time traffic?

Answer options

• A. 25 Mbps
• B. 50 Mbps
• C. 33 Mbps
• D. 75 Mbps

Correct answer: C

Explanation

The correct answer is 33 Mbps because it allows for a balance between strict-priority traffic and other types of traffic within the 100 Mbps capacity. Choosing a limit that is too high, such as 50 Mbps or 75 Mbps, would compromise the bandwidth available for other applications, while 25 Mbps would not adequately support the real-time traffic demands.
