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

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:

The primary difference between SRE and DevOps lies in their implementation focus and origins, though they share similar objectives. According to Google’s official SRE documentation:

“SRE can be seen as a specific implementation of DevOps with some idiosyncratic extensions.”

— Site Reliability Engineering Book, Chapter: What is Site Reliability Engineering?

While DevOps is a broad cultural and organizational philosophy aimed at closing the gap between development and operations through collaboration and automation, SRE provides a concrete, engineering-driven approach to achieving those goals — particularly through practices like error budgets, SLIs/SLOs, toil reduction, and incident response.

SRE focuses heavily on the post-production lifecycle — including reliability, monitoring, capacity planning, and incident response — whereas DevOps includes these concerns but emphasizes the entire software delivery lifecycle. Hence, Option A is the correct and most accurate answer.

Options B and C are incorrect:

B wrongly implies a division of roles (DevOps = developers, SRE = infrastructure), which is not how these frameworks operate.

C misrepresents SRE — it does not build silos but instead emphasizes shared responsibility and transparency in production systems.

D is incorrect because, while aligned, SRE and DevOps are not identical.

Comprehensive and Detailed Explanation From Exact Extract:

A Service Level Indicator (SLI) is a measurement of some aspect of reliability (e.g., latency, availability, quality). One of its defining characteristics is that it must be measured over a specific time window. Without a time horizon, the SLI has no actionable meaning.

From the Site Reliability Engineering Book, Chapter “Service Level Indicators”:

“An SLI is a quantitative measure of some aspect of the level of service that is provided. SLIs are evaluated over a specific period of time in order to understand reliability as experienced by the user.”

The SRE Workbook further states:

“Every SLI must define a measurement window. Without a time horizon, the indicator cannot be used to calculate SLO compliance.”

Why the other options are incorrect:

A SLIs do not need to appear in an SLA; SLAs are external contracts, SLOs/SLIs are internal engineering tools.

B SLIs may include client-side, server-side, or network metrics depending on what reflects user experience.

D SLI agreement is not defined by SRE vs. Agile teams; it is defined by business and user need.

Thus, the correct answer is C.
