Show answer & explanation
Correct answer: B
Solution:
Compute total bits per minute: 12,000 frames/min × 10,000 bits/frame = 120,000,000 bits/min.
Convert to bits per second: 120,000,000 ÷ 60 = 2,000,000 bits/s.
Convert to megabits per second: 2,000,000 ÷ 1,000,000 = 2 Mbps.
Throughput = 2 Mbps. Compared to the 10 Mbps link bandwidth, utilization ≈ 20%.
