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

Comprehensive and Detailed Explanation From Exact Extract:

Customer Reliability Engineering (CRE) is described in Google's SRE literature as an extension of SRE practices outward to customers who run workloads on cloud platforms. The SRE Book and the SRE Workbook state: “CRE is the practice of sharing SRE principles with customers, working closely with their operations teams, and establishing shared responsibility for reliability.” (SRE Workbook – Chapter: Customer Reliability Engineering). A CRE team collaborates directly with customer engineering and operations teams to identify reliability risks, review architectures, and co-manage SLOs, but does not redesign cloud services or build new features.

Option D matches the exact intention: CRE integrates with the customer’s operations team to share reliability responsibilities, applying SRE methods to customer systems and ensuring both customer and provider work jointly on reliability goals.

Option A is incorrect—CRE does not redesign cloud services.

Option B misinterprets CRE as improving the provider’s internal systems.

Option C incorrectly focuses on feature shipping; CRE is about reliability guidance, not feature delivery.

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

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.

Comprehensive and Detailed Explanation From Exact Extract:

When a team exceeds its error budget, SRE practice requires applying error budget policies that restrict feature releases and shift focus toward reliability improvement. The idea is to prevent further degradation of user experience and ensure the service meets the agreed reliability targets.

The Site Reliability Engineering Book, Chapter “Service Level Objectives,” states:

“If the service exceeds its error budget, all new feature launches or risky changes are halted until reliability returns to acceptable levels. Engineering work should be directed toward addressing the causes of the budget overrun.”

This aligns with option A, which describes a reliability-focused response during sprint planning. Limiting sprint planning to post-mortem action items and reliability improvements is a direct application of error budget policies.

Additional guidance from the SRE Workbook:

“Error budget burn should directly influence decision-making. When the budget is exhausted, the team must focus on remediation work rather than new features.”

Why the other options are incorrect:

B Reviewing the error budget’s realism can be done periodically, but it is not the immediate consequence of a breach.

C Extending the error budget invalidates its purpose and is discouraged.

D Ignoring the error budget contradicts the entire SRE model and Google’s official guidance.

Therefore, A is the only correct answer.
