Site Reliability Engineering Principles Questions

Apply site reliability engineering principles to design resilient large scale systems. Topics include service level indicators and service level objectives, error budgets and how to use them to prioritize work, capacity planning and performance testing, fault isolation and redundancy patterns across regions, chaos engineering and failure injection, incident response and blameless postmortems, automation to reduce manual toil, and trade offs between availability, consistency, and cost. Interviewers expect familiarity with recovery strategies, monitoring, alerting, and reliability driven design decisions.
