What is the maximum cable length for IEEE 1394a?

4.5 meters
10 meters
2.5 meters
100 meters

The correct answer is: 4.5 meters

The maximum cable length for IEEE 1394a is 4.5 meters because of the technical limitations of the cable and data transfer rate. While it is possible to have longer cables, the signal may degrade and cause errors in data transmission. Options B, C, and D are incorrect because they have longer cable lengths which exceeds the maximum length. Option B, 10 meters, is incorrect because it is more than double the maximum length. Option C, 2.5 meters, is incorrect because it is too short and may not allow for sufficient data transfer. Option D, 100 meters, is incorrect because it is significantly longer and would compromise the data transfer rate.
