Multiple Choice
Consider a disk queue holding requests to the following cylinders in the listed order: 210, 67, 11, 99, 87, 90, 19, 150. Using the C-SCAN scheduling algorithm, what is the order that the requests are serviced, assuming the disk head is at cylinder 88 and moving upward through the cylinders?
A) 87 - 90 - 99 - 67 - 19 - 11 - 150 - 210
B) 210 - 67 - 11 - 99 - 87 - 90 - 19 - 150
C) 90 - 99 - 150 - 210 - 11 - 19 - 67 - 87
D) 90 - 99 - 150 - 210 - 87 - 67 - 19 - 11
