What is a primary responsibility of an SRE in terms of system reliability?

• A. Defining product features
• B. Implementing and maintaining monitoring thresholds and alerts
• C. Designing UI elements
• D. Managing database schema migrations

Answer: (B)

Reliability hinges on observability and timely response, so an SRE’s primary job is to implement and maintain monitoring thresholds and alerts to detect problems and trigger fast remediation. By selecting key signals like latency, error rate, and saturation, setting sensible thresholds, and configuring alerts and runbooks, SREs ensure incidents are noticed quickly and handled efficiently, supporting service availability and helping meet SLOs. The other activities—defining product features, designing UI, or managing database migrations—are not centered on keeping the system reliably available.
