Exam CV0-003 topic 1 question 205 discussion

(A) 99.00% uptime annually = 3d, 14h, 56m allowed downtime (B) 99.90% uptime annually = 8h, 41m allowed downtime (C) 99.95% uptime annually = 4h, 20m allowed downtime (D) 99.99% uptime annually = 52m allowed downtime While both "C" and "D" are under the max allowed downtime, the architect is looking for deployment services, not application services so the correct answer is "C".

A 99.99% availability SLA will allow for approximately 52.56 minutes of downtime per year, which is well below the five-hour threshold. This means the cloud architect can confidently pursue this SLA if minimizing downtime is a top priority for his deployment. Let me break it down step by step: 1. Calculate Total Hours in a Year: There are 365 days in a year: 365 days × 24 hours/day = 8,760 hours/year 2. Determine Uptime Allowed by 99.99% Availability: If your service has 99.99% availability, the downtime can be calculated as: Downtime = (1−0.9999) × 8,760 hours ≈ 0.876 hours/year This is approximately 52.56 minutes of downtime annually. Comparison to Five Hours: Since 52.56 minutes is significantly less than five hours, a 99.99% SLA not only meets but far exceeds the requirement of allowing for no more than five hours of downtime annually.

Total uptime considering the maximum allowed downtime is 8755/8760 hours = 99.942. C is the correct answer.

The architect is deploying an application. He wants guaranteed application uptime.

The total SLA is the multiplication between all 3 components. So only D is correct which is 99.97% of composed SLA.

Ive done the maths. 99.95 X 99.99 X99.95 then multipled by 365 gives you 364.59. So you lose .41 of a day, thats 9.84 hours. Correct answer is D, you lose approx 2.8 hours.

C is the one that is closest to the hour requirement
