Designing Cisco Network Service Architectures (ARCH, legacy) — Question 65

A customer has an existing WAN circuit with a capacity of 10 Mbps. The circuit has 6 Mbps of various user traffic and 5 Mbps of real-time audio traffic on average.
Which two measures could be taken to avoid loss of real time traffic? (Choose two.)

Answer options

• A. Police the traffic to 3.3 Mbps and allow excess traffic to be remarked to the default queue.
• B. Configure congestion avoidance mechanism WRED within the priority queue.
• C. Ensure that real time traffic is prioritized over other traffic.
• D. Police the traffic to 5 Mbps and allow excess traffic to be remarked to the default queue.
• E. Increase the WAN circuit bandwidth.

Correct answer: C, E

Explanation

Prioritizing real-time traffic (option C) ensures it has the necessary bandwidth during congestion, while increasing the WAN circuit bandwidth (option E) directly provides more capacity for all traffic types. Options A and D would not adequately address the need for real-time traffic, as they limit bandwidth rather than prioritizing or increasing it. Option B, while helpful for managing congestion, does not specifically prioritize real-time audio traffic.
