DevOps-SRE Exam Dumps : Site Reliability Engineering (SRE) Foundation v1.2

Comprehensive and Detailed Explanation From Exact Extract:

SRE defines effective monitoring as comprehensive observability across all layers of a system, including latency, traffic, errors, saturation, dependencies, and infrastructure. The SRE Book states: “Monitoring must offer insight across all system components, enabling teams to rapidly detect and diagnose issues.” (SRE Book – Monitoring Distributed Systems). Observability instrumentation (logs, metrics, traces) provides the necessary depth for reliable digital experience monitoring.

Option B captures this exactly: broad observability across all components and layers.

Option A rejects modern observability practices—contradicting SRE guidance.

Option C is too narrow (network-only).

Option D focuses only on advanced technologies, not comprehensive coverage.

Thus, B is the best answer.

Comprehensive and Detailed Explanation From Exact Extract:

In a safety culture, SRE emphasizes psychological safety so engineers can work effectively in production without fear of blame. However, safety never removes accountability. Engineers must take responsibility for their actions, decisions, and assumptions, particularly during incidents.

The Site Reliability Engineering Book, Chapter “Postmortem Culture,” states:

“Blamelessness does not eliminate accountability. Individuals must still explain the context, assumptions, and reasoning behind their decisions so that the organization can learn.”

Google stresses that:

Engineers must feel safe to act and report issues

Engineers must remain responsible and accountable

Accountability enables learning, not punishment

Why other options are incorrect:

A Sharing incidents on social media violates confidentiality

C Blameless postmortems are required, not skipped

D Avoiding on-call is contrary to SRE responsibilities

Thus, B is correct.

Comprehensive and Detailed Explanation From Exact Extract:

Embracing failure—through practices such as blameless postmortems, chaos engineering, and proactive detection—enables organizations to improve their incident response performance. This directly improves:

MTTD (Mean Time to Detect)

MTTR (Mean Time to Recover)

The Site Reliability Engineering Book, chapter “Postmortem Culture,” states:

“By examining failures without blame and learning from them, organizations improve their ability to detect issues faster and recover more quickly.”

Similarly, in the SRE Workbook, section on incident response:

“Learning from incidents is essential to reducing time to detection and time to mitigation.”

Why the other options are incorrect:

A MTBSI (Mean Time Between System Incidents) is influenced by architecture and testing, not directly by embracing failure.

B These are DORA metrics — important, but not primarily tied to failure-embracing practices.

C Too vague and not a standard SRE metric pair.

Thus, D is the correct answer.
