Score Higher on Verified DevOps-SRE | Site Reliability Engineering (SRE) Foundation v1.2 Exam Questions with Answers

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.

Comprehensive and Detailed Explanation From Exact Extract:

Google’s definition is explicit: “An SLI is a carefully defined QUANTITATIVE measure of some aspect of the level of service provided.” (SRE Book – Chapter: Service Level Objectives). Examples include error rate, latency, throughput, and availability. SLIs are measurements, not targets—targets are SLOs.

Option D repeats Google’s definition almost exactly.

Option C incorrectly describes an SLO (a target), not an SLI.

Options A and B mention subjective assessments—SRE explicitly rejects subjectivity in measurement, stating: “SLIs must be objective and measurable.”

Thus, D is the correct and SRE-authentic answer.

Comprehensive and Detailed Explanation From Exact Extract:

SRE is built on transparency and broad information sharing. The SRE Book states: “High-quality operations require that information flows freely between product development, SRE, and associated teams.” (SRE Book – Chapter: Communication and Collaboration). Effective incident management also depends on complete data availability: “Centralized, shared information reduces cognitive load and improves incident resolution.” (SRE Workbook – Incident Management).

Option B aligns perfectly with SRE principles: data must flow freely, ensuring everyone has access to metrics, logs, architecture details, incident context, and SLOs.

Options A, C, and D promote restricted or fragmented data practices, which are directly contrary to SRE design. SRE teams avoid information silos.

Thus, B is correct.
