C. 83.3% Total Operation: 12*5= 60 Downtime: 1 + 4 + 1 + 4 = 10 Uptime = 60 - 10 = 50 Availability = Uptime / (Uptime + Downtime) = 50 /(50+10) = 0.833 * 100 = 83.3%

Selected Answer: C
C is a correct answer because all ports must be operational from 8 AM to 8 PM, Monday through Friday, and the last point of failure at Saturday that not enrolled at our system Uptime, and any hour before 8 AM and before 8 PM doesn't be enrolled at our system Uptime. Total Time = 5 * 12 = 60 The Down Time = 10 hours A = ((60 - 10)/60)*100 = 83.3%
