Which describes a benefit of PacketCable's managed IP network?

• A. They deliver higher voice quality by using a managed IP network rather than the public Internet
• B. They are cheaper but less reliable
• C. They require no QoS features
• D. They deliver video only, not voice

Answer: (A)

Managed IP networks provide higher voice quality by guaranteeing performance for voice traffic through quality of service, traffic prioritization, and predictable resource allocation. Because the network is managed rather than relying on the public Internet, voice packets encounter lower latency and jitter and fewer drops, which translates to clearer calls. The public Internet lacks these guarantees, so using a managed network makes a noticeable difference in call quality. This isn’t about being cheaper and less reliable; the managed approach aims for reliability and consistent performance, and QoS features are essential for delivering good voice quality. It also isn’t limited to video only—voice is the primary benefit described here.
