Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 82

When a remote office location is set up with limited bandwidth resources, which codec would allow the most voice calls with the limited bandwidth?

Answer options

• A. G.711
• B. G.722
• C. G.723
• D. G.729

Correct answer: D

Explanation

G.729 is the correct choice because it uses a lower bit rate of around 8 kbps, allowing more simultaneous calls over limited bandwidth. In contrast, G.711 and G.722 consume significantly more bandwidth, while G.723, although more efficient than G.711, still does not match the efficiency of G.729.
