Peoplecert PeopleCert DevOps Site Reliability Engineer (SRE) Sample Questions (Q44-Q49):

NEW QUESTION # 44
What is the MOST widely tracked Service Level Objective (SLO)?

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Availability is the most widely tracked and commonly understood SLO across nearly all digital services. It measures whether users are able to successfully access and use the system. Because unavailability directly impacts user experience, revenue, trust, and reliability, it is the primary SLO used across industries.
The Site Reliability Engineering Book, Chapter "Service Level Objectives," states:
"Availability is one of the most common and important SLOs since it reflects the basic ability of the service to function for users." The SRE Workbook also notes:
"Availability targets (e.g., 99.9%, 99.99%) are the most widely used form of SLOs and form the foundation of error budget policies." While performance SLOs are also common, availability SLOs are almost universal and foundational.
Thus, D. Availability is the correct answer.

NEW QUESTION # 45
Where should an organization store versioned and signed artifacts that are used to deploy system components?

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
SRE and modern DevOps best practices require that build artifacts-such as binaries, container images, and deployment packages-be stored in a secure, versioned artifact repository. These repositories ensure integrity, traceability, immutability, and security of deployment packages.
While the SRE Book does not use the ITIL term DML, it emphasizes:
"All production binaries should be stored in a secure, versioned repository to ensure consistent, repeatable, and trustworthy deployments."
- Site Reliability Engineering Book, section on Release Engineering
The SRE Workbook expands on this principle by emphasizing signed and verified artifacts:
"To ensure safe rollout, artifacts must be built once, stored securely, signed, versioned, and deployed from a controlled artifact repository." Why the other options are incorrect:
* A A CMS manages configuration, not deployment artifacts.
* B Subversion is a source code repository, not an artifact repository.
* C A DML is an ITIL concept, but SRE practice does not rely on it; instead, SRE uses modern artifact repositories (e.g., GCR, ACR, Artifactory).
Thus, the correct answer is D.

NEW QUESTION # 46
Which of the following features of Puppet Labs is described as the ability to locate, identify, and group cloud nodes?

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
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.

NEW QUESTION # 47
In a safety culture, engineers are allowed to do more with the production environment without fear of repercussions.
What else do engineers need to do?

Answer: B

Explanation:
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.

NEW QUESTION # 48
Service Level Objectives (SLOs) are tightly related to

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Service Level Objectives (SLOs) are directly tied to user experience, and this connection is central to the SRE philosophy. The purpose of an SLO is to define how well a service must perform to keep users satisfied, without exceeding what is necessary or economically practical.
The Site Reliability Engineering Book, Chapter "Service Level Objectives," states:
"The most important directive when defining SLOs is that they must reflect the expectations and needs of the users of the service." Similarly, the SRE Workbook, Chapter "Implementing SLOs," highlights:
"SLOs are a tool to measure and control the reliability as experienced by the user." This makes it clear that SLOs are fundamentally user-centric. They are not based on internal engineering preferences, management goals, or operational convenience.
Why the other options are incorrect:
* B. Management approval - SLOs are not driven by management goals but by user needs.
* C. Change success rate - While related to reliability practices, change success is not the basis of SLO creation.
* D. Toil reduction - Toil is unrelated to defining service-level targets.
Therefore, the correct answer is A.
