Solution

The correct answer is 2 seconds

SOLUTION:

The maximum duration for which the computer can transmit at the full 10 Mbps can be calculated using the concept of token bucket.

• Token rate into bucket = 2 Mbps
• Output rate of bucket = 10 Mbps
• Effective rate = 10-2 = 8 Mbps
• Bucket capacity is full, 16 Mb
• So, at effective rate bucket will drain in 16/8 = 2s
