CCDE: Cisco Certified Design Expert (Practical) — Question 52

Which two actions ensure voice quality in a branch location with a low-speed, high-latency WAN connection? (Choose two.)

Answer options

• A. Prioritize voice packets.
• B. Replace any electrical links with optical links.
• C. Increase memory on the branch switch.
• D. Fragment data packets.
• E. Increase WAN bandwidth.

Correct answer: A, D

Explanation

Prioritizing voice packets ensures that voice traffic is transmitted with higher precedence over other types of data, which is crucial for maintaining call quality in a low-speed, high-latency environment. Fragmenting data packets can help manage congestion and reduce delays, making it a useful strategy in this scenario. The other options, such as replacing links or increasing memory, do not directly address the issues related to voice quality over a WAN connection.
