A 8-Mbps token ring has a token holding timer value of 10 msec. What is the longest frame (assume header bits are negligible) that can be sent on this ring?

A. 8000 B frame
B. 80,000 B frame
C. 8 x 105 bit frame
D. 10,000 B frame

Answer: Option D

Explanation:

At 8 Mbps, a station can transmit 80,000 bits or 10,000 bytes in 10 msec. This is an upper bound on frame length. From this amount, some overhead must be subtracted, giving a slightly lower limit for the data portion. Therefore, 10,000 B frame is the correct answer.
