CCSP Cloud Concepts, Architecture, and Design Practice Question
An organization is evaluating a cloud provider's SLA for a critical application. The provider offers a 99.95% uptime SLA with a 10% service credit for each 30-minute downtime period exceeding the threshold. The organization's business impact analysis requires a maximum downtime of 4.38 hours per year. Does the provider's SLA meet this requirement, and what is the annual allowed downtime based on the SLA?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Yes, because the SLA guarantees 99.95% uptime, which equals 4.38 hours of downtime per year.
99.95% uptime allows 0.05% downtime per year. 0.05% of 365 days * 24 hours = 0.05% * 8760 hours = 4.38 hours. Exactly meets the requirement. The service credit mechanism does not change the allowed downtime.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
No, because service credits only apply after 30 minutes of downtime, so actual uptime is lower.
Why it's wrong here
Service credits are a remedy, not a guarantee of uptime; the SLA still states 99.95% uptime.
- ✗
Yes, because the 10% credit effectively increases the uptime commitment.
Why it's wrong here
Service credits do not change the uptime percentage; they compensate for breaches.
- ✗
No, because 99.95% uptime allows 5 hours of downtime per year.
Why it's wrong here
Incorrect calculation; 99.95% allows 4.38 hours, not 5.
- ✓
Yes, because the SLA guarantees 99.95% uptime, which equals 4.38 hours of downtime per year.
Why this is correct
Correct calculation: 0.05% of 8760 hours = 4.38 hours.
