DevOps-SRE Exam Dumps - PeopleCert DevOps Questions and Answers

Comprehensive and Detailed Explanation From Exact Extract:

SRE strengthens DevOps by adding reliability engineering, SLOs, error budgets, and production-focused automation. One key improvement is that the CI/CD pipeline extends safely into production using automated, tested, reliable deployment mechanisms.

The Site Reliability Engineering Book, “Release Engineering” chapter states:

“SRE complements DevOps by creating safe pathways for automated production deployments through engineering practices such as canarying, automation, and release gates.”

The SRE Workbook adds:

“SRE helps mature DevOps pipelines so they can operate safely in production, enabling continuous delivery to reach all the way through deployment.”

Why the other options are incorrect:

B SRE makes CD more necessary, not redundant

C SRE does not replace DevOps engineers

D IaC does not require moving to the cloud

Thus, the correct answer is A.

Comprehensive and Detailed Explanation From Exact Extract:

Google’s SRE approach emphasizes a blameless postmortem culture as a core learning mechanism. After a major outage, SRE teams conduct structured analyses to understand the root causes, contributing factors, and systemic weaknesses. The SRE Book defines this culture explicitly: “Postmortems are written analyses following incidents, designed to capture what happened, why it happened, and how to prevent the issue from recurring.” (SRE Book – Chapter: Postmortem Culture). This learning-focused approach reduces blame, increases resilience, and improves future reliability.

Option C aligns exactly with this principle.

Option A (follow-up culture) is vague and not an SRE term.

Option B (major incident culture) refers to incident handling, not learning afterward.

Option D (problem culture) is unrelated to SRE’s structured post-incident learning.

Thus, C is correct.

Comprehensive and Detailed Explanation From Exact Extract:

High turnover in IT operations roles is often driven by a combination of factors, not just one. The Google SRE Book, Chapter “Eliminating Toil,” outlines that excessive toil, unpredictable work, and overload contribute to burnout and churn:

“Excessive operational workload and interrupt-driven work lead to burnout and high attrition among engineering and operational staff.”

The SRE Workbook adds:

“Teams overwhelmed with toil struggle to innovate, automate, or develop new skills, creating frustration and increasing turnover.”

Each option listed represents a recognized driver of burnout in SRE and operations environments:

Overload and disruptive work patterns are known contributors to burnout.

Lack of time for skills development demotivates engineers and prevents career growth.

Backlog-driven cultures force teams into reactive rather than proactive work.

The combination of these factors matches common causes of attrition in operations teams. Therefore, all of the above is the correct answer.

In the context of SRE tooling and automation, configuration management platforms like Puppet support large-scale infrastructure reliability by enabling consistency, repeatability, and automation. Puppet’s Discovery capability allows engineers to automatically locate, identify, classify, and group cloud nodes or infrastructure resources. Although not directly from Google’s SRE Book, Discovery aligns with SRE principles of reducing toil and enabling scalable automation. SRE emphasizes “automating away the manual work of locating and managing infrastructure at scale.” (SRE Book – Chapter: Eliminating Toil). Puppet Discovery does precisely this by automatically scanning environments, detecting nodes, and providing metadata to group or manage them.

Option A (Provisioning) refers to creating infrastructure, not identifying it.

Option B (Delivery) relates to CI/CD processes.

Option D (Insight) relates to analytics and reporting, not node identification.

Therefore, C. Discovery is correct as it directly represents the capability described.
