Comprehensive and Detailed Explanation From Exact Extract:
A Production Readiness Review (PRR) is a core SRE practice ensuring that a service meets specific reliability, operational, monitoring, and alerting standards before SRE assumes responsibility. The Site Reliability Engineering (SRE) Workbook states: “PRRs validate that a service is prepared for production and ready for SRE engagement, ensuring operational readiness, monitoring completeness, on-call preparation, and automation maturity.” The goal is not merely organizational handover but ensuring the service is fully prepared for reliable operation in production.
Option A fits this definition exactly: ensuring the service is ready for SRE support.
Option B focuses on development/testing readiness, not production readiness.
Option C references standards/frameworks not part of PRR’s purpose.
Option D is only a partial implication—transition of accountability happens after PRR readiness, not the main purpose of PRR.
Thus, A is the correct SRE-aligned answer.
