ITPEC FE Morning April 2022 Question 56
ITPEC FE Morning April 2022 — Question 56 of 80
Service hours: 16 hrs/day × 30 days = 480 hrs/month. With 99% availability, allowed downtime is 480 × (1 - 0.99) = 480 × 0.01 = 4.8 hours.
Why not others:
- (a) 1.2 — implies 99.75% availability, stricter than required
- (b) 3.0 — implies 99.375%, not matching any standard calculation
- (d) 7.2 — allows 1.5% downtime, violates the 99% SLA
Key rule: max_downtime = total_service_hours × (1 - availability%) — always calculate total service hours first, not calendar hours.
