Comprehensive and Detailed Explanation From Exact Extract:
SRE emphasizes decision-making based on measured data, not intuition. The SRE Book explains: “Monitoring and SLOs provide an objective basis for decision-making, replacing guesswork with quantifiable data.” (SRE Book – SLOs & Monitoring). Data enables SRE teams to understand system behavior, validate assumptions, detect anomalies, and prioritize engineering work. The primary benefit is not merely collecting data, but analyzing and interpreting it to support decisions grounded in facts rather than opinion.
Option A accurately reflects this principle: data analysis and interpretation enable fact-based decisions, which is the core justification for SRE’s reliance on SLIs and observability signals.
Option B overstates by claiming data alone is always sufficient.
Option C refers to data mining, which is not a core SRE concept.
Option D is partially true but narrower than the SRE philosophy of data-driven operations.
Thus, A is the most accurate SRE-aligned answer.
