ITPEC FE Subject A October 2025 — Question 43 of 60
Calculate maximum allowed downtime from SLA conditions:
- •Service hours: 7 AM to 11 PM =
16 hours/day - •Business days:
30 - •Total service hours:
16 × 30 = 480 hours - •Agreed availability:
99% - •Max downtime:
480 × (1 - 0.99) = 480 × 0.01 = 4.8 hours
Why not others:
- (a) 1.2 — would imply 99.75% availability, stricter than required
- (b) 3.0 — does not match any calculation from given values
- (d) 7.2 — uses 24 hours/day (720 × 0.01), but service runs only 16 hours/day
Key rule: Downtime allowance = total service hours × (1 − availability%). Only count hours when the service is scheduled to run.
