What is a service level agreement (SLA) and what metrics are typical?

• A. An SLA defines pricing tiers for services.
• B. An SLA defines uptime, performance, and support response times; metrics include availability percentage, MTTR, latency, and throughput.
• C. An SLA describes architectural diagrams.
• D. An SLA ensures data sovereignty.

Answer: (B)

A service level agreement is a formal contract that sets the expected level of service a provider commits to deliver, translating customer needs into measurable targets for quality, availability, and support. The metrics used to gauge these targets typically include availability percentage (uptime), mean time to repair (MTTR), latency (response time), and throughput (volume of work processed per unit time). This combination gives a clear picture of how reliably and quickly the service operates, and provides a basis for monitoring and potential credits if targets aren’t met. Other options describe pricing structures, architectural diagrams, or data residency constraints—areas that deal with cost, design, or legal requirements rather than the service performance commitments covered by an SLA.
