Which of the following BEST illustrates the engineering approach for work done within SRE?

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.
