Explanation
SLIs, SLOs, and SLAs are distinct but interrelated concepts in service reliability. SLIs are metrics that measure service performance, SLOs are specific targets for those metrics, and SLAs are formal agreements with customers that outline expectations and penalties. Understanding the difference between these terms is critical for ensuring clarity and alignment in service reliability management.
- A. Correct.
Correct: SLIs are metrics that quantitatively measure specific aspects of service performance, such as availability, latency, or error rates.
- B. Correct.
Correct: SLOs are specific, measurable targets for SLIs that define the desired level of service performance, such as 99.9% availability.
- C. Incorrect.
Incorrect: SLAs are external agreements with customers, not internal benchmarks. Internal benchmarks may exist but are not referred to as SLAs.
- D. Correct.
Correct: SLAs are formal agreements between a service provider and its customers, defining the performance standards and penalties if those are not met.
- E. Incorrect.
Incorrect: SLIs are not contractual obligations; they are simply metrics used to track performance.
