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.
