Which of the following BEST illustrates the engineering approach for work done within SRE?
Correct Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract: Google defines SRE as “what happens when you ask a software engineer to design an operations function.” (SRE Book – Introduction). The core engineering approach in SRE focuses on: Eliminating toil Building scalable systems Applying software engineering to operational challenges Learning from previous solutions and patterns The SRE Book emphasizes: “SREs focus on designing and engineering solutions that reduce manual operations and scale service delivery.” (Chapter: Eliminating Toil). This aligns directly with Option B: designing a solution to eliminate toil and scale service delivery, informed by prior successful engineering patterns. Option A focuses only on automating a single tuning activity—not holistic engineering. Option C describes deployment, not engineering approach to operations. Option D is about incident response, not engineering strategy. Thus, B is the best representation of SRE’s engineering approach.

Question 2
If an organization wants to promote changes automatically and reduce dependency errors, what steps should they take?
Correct Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract: Using verified and signed artifacts is essential for safe automation, ensuring that deployments are consistent and free of dependency or supply chain errors. This is a fundamental principle in Google’s release engineering and SRE practices. The Site Reliability Engineering Book, chapter “Release Engineering,” states: “Releases should be built once, tested, signed, and stored in a secure repository. Only signed and verified artifacts should be promoted to production to prevent configuration drift and dependency inconsistencies.” The SRE Workbook echoes this: “Automated promotions depend on the integrity and immutability of artifacts. Signed artifacts ensure consistency and prevent errors related to mismatched dependencies.” Why the other options are incorrect: A External visibility is irrelevant and may create security risks. C Error budgets relate to reliability, not artifact promotion. D SLOs do not define artifact signing; this is handled by release engineering processes. Thus, the correct answer is B.
