Peoplecert PeopleCert DevOps Site Reliability Engineer (SRE) Sample Questions (Q22-Q27):NEW QUESTION # 22
Which scenario BEST illustrates the swarming concept used during incident management?
  • A. A mid-level support team continually monitors escalated incidents to assigned teams to ensure they are making progress
  • B. An incident analyst rote escalates by assessing a consolidated list of next-level support teams and their area of expertise
  • C. A group of specialist teams meet and review a queue of escalated incidents to determine who should work on which one
  • D. A high-level specialist support team constantly reviews their incoming incident queue to respond instantly to escalations
Answer: C

NEW QUESTION # 23
When applied to service levels, the principle of decreasing marginal productivity can be represented in three stages. Which of the following is NOT one of these stages?
  • A. Increasing returns
  • B. Diminishing returns
  • C. Possible returns
  • D. Negative returns
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
SRE applies economic principles, including diminishing marginal returns, to reliability engineering. As per the SRE Book: "Improving reliability becomes more expensive as the target approaches 100%, moving from increasing returns, to diminishing returns, and eventually negative returns." (SRE Book - SLO Economics).
This framework helps explain why striving for 100% availability is impractical and cost-ineffective.
The three recognized stages are:
* Increasing returns - early improvements are inexpensive and highly impactful
* Diminishing returns - costs rise while benefits shrink
* Negative returns - achieving additional "nines" may reduce value due to slowed innovation
"Possible returns" is not part of this model.
Thus, D is the correct answer.

NEW QUESTION # 24
Which of the following BEST defines the golden signal for errors?
  • A. The time it takes to service successful as well as failed requests
  • B. The rate of failed requests either explicitly implicitly, or by policy
  • C. The demand that is placed on your system by me volume of requests
  • D. The percent of capacity used by your system for current requests
Answer: B

NEW QUESTION # 25
Which of the following is the BEST description of a Customer Reliability Engineer (CRE)?
  • A. They take a software engineering approach to redesign all cloud services
  • B. They integrate with the customer's operations team to share responsibilities
  • C. They work with the cloud provider's SRE team to ship and build new features
  • D. They use deep engineering expertise to improve the cloud provider's services
Answer: B
Explanation:
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.

NEW QUESTION # 26
What is the goal of SRE?
  • A. To spend 50% of a SRE's time on operational tasks and 50% of the time on development tasks to reduce toil
  • B. To create ultra-scalable and highly reliable distributed software systems
  • C. To ensure that Service Level Objectives are consistently met through monitoring and observability
  • D. To create highly reliable post-deployment operational systems that align with DevOps and Agile
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The goal of Site Reliability Engineering (SRE) is to create ultra-scalable and highly reliable distributed software systems. This principle is clearly articulated in the foundational text of SRE, the Google Site Reliability Engineering book.
From Chapter 1: Introduction of the Site Reliability Engineering book:
"SRE is what happens when you ask a software engineer to design an operations team. Our approach to service management is rooted in our belief that engineering work to create scalable and highly reliable systems is critical to the success of modern software."
- Site Reliability Engineering Book, Chapter 1
This statement establishes that building and maintaining scalable, reliable systems is the core mission of SRE.
While concepts like reducing toil (option A), implementing SLOs (option B), and aligning with DevOps (option C) are vital components of the SRE practice, they support the overarching goal - which is option D.
Therefore, the correct answer is D: To create ultra-scalable and highly reliable distributed software systems.
