Implementing Cisco Video Network Devices (CIVND, legacy) — Question 37

What are the best practices for maintaining a high-quality video call regarding latency, jitter, and packet loss?

Answer options

• A. 20-ms one-way delay, no jitter, no packet loss
• B. less than 150-ms one-way delay, 30-ms jitter, less than 3 percent packet loss
• C. 150- to 400-ms one-way delay, 50-ms jitter, 5 percent packet loss
• D. 500-ms one-way delay, 50-ms jitter, 5 percent packet loss

Correct answer: B

Explanation

Option B is correct as it specifies a one-way delay of less than 150 ms, which is acceptable for a good video call, with 30 ms of jitter and under 3 percent packet loss, ensuring a smooth experience. Options A, C, and D either exceed acceptable limits for latency or jitter, or have higher packet loss, making them unsuitable for maintaining high-quality video calls.
