Peoplecert PeopleCert DevOps Site Reliability Engineer (SRE) Sample Questions (Q66-Q71):

NEW QUESTION # 66
Which of the following terms is BEST described by the definition below?
"The probability that the system will meet certain performance standards and yield correct output for a specific time."

A. Throughput
B. Durability
C. Reliability
D. Availability

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The SRE Book defines reliability as: "the probability that a system will perform its intended function correctly for a specified period of time." (SRE Book - Introduction). Reliability focuses on correctness and consistent performance, not simply uptime. Availability (option A) refers to system uptime or accessibility.
Durability (option C) refers to long-term data persistence. Throughput (option D) measures volume of work processed over time.
Because the definition explicitly mentions probability of meeting performance standards and correct output over time, it directly matches the SRE definition of reliability.
Thus, B is correct.

NEW QUESTION # 67
Which of the following is the MOST likely outcome when the workforce puts the "parts" before the "whole"?

A. Increased introversion and decreased efficiency
B. A focus on common interests and lesser conflicts
C. A voluntary sharing of resources and information
D. Increased employee motivation and morale

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
SRE emphasizes organizational alignment and collaboration, warning against siloed thinking. The SRE Book highlights: "Local optimizations at the expense of the broader system lead to inefficiency, misalignment, and reduced reliability." When individuals or teams focus only on their own "parts" instead of shared goals ("the whole"), it results in decreased cross-team communication, isolation, operational friction, and reduced efficiency.
Option B captures this SRE-documented outcome: increased introversion (siloing) and decreased efficiency.
Option A and D describe positive outcomes that contradict SRE principles of collaboration.
Option C implies healthy sharing, which does not result from silo-first behavior.
Thus, B is correct.

Site Reliability Engineering, Chapter: "Organization and Culture."
The Site Reliability Workbook, sections on collaboration, alignment, and anti-silo culture.

NEW QUESTION # 68
The value of data-driven measurements can be MOST accurately explained by which of the following?

A. The garnering of data will provide an the necessary facts to enable better decisions
B. Data mining enables an organization to determine the legitimacy of all metrics
C. An analysis and understanding of data helps to ensure fact-based decision-making
D. Objectives can only be appropriately designed when based upon actual data

Answer: C

NEW QUESTION # 69
Which of the following is a principle of SRE-Led Service Automation?

A. No automated tests in production
B. Using unsigned artifacts in production
C. Environments provisioned using IaC
D. Adding as much hardware as possible

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
SRE-led service automation focuses on making environments reproducible, reliable, and consistent. One of the key principles aligned with Google SRE practices is the use of Infrastructure as Code (IaC), which allows environments to be provisioned automatically, consistently, and predictably.
The Site Reliability Engineering Book, in its discussions on automation, states:
"Automation implemented as code ensures that environments are consistent, repeatable, and less prone to human error." The SRE Workbook expands on this concept:
"Infrastructure as Code allows services to scale and evolve reliably by ensuring that configuration and infrastructure changes are automated and version-controlled." IaC is fundamental to:
* Reducing toil
* Increasing reliability
* Enabling consistent automation across environments
* Reducing configuration drift
Why the other options are incorrect:
* A SRE supports testing in production; it does not ban automated tests.
* C Using unsigned artifacts violates security and reliability best practices.
* D Adding hardware is not an automation principle and contradicts efficiency goals.
Thus, the correct answer is B.

NEW QUESTION # 70
Which scenario BEST illustrates how stability and agility can be achieved with simplicity?

A. An SRE team is protecting reliability by using processes and procedures to control updates
B. An SRE team is releasing a major update by automating continuous and small deployments
C. An SRE team is creating procedures, practices, and tools that render software more reliable
D. An SRE team is adopting easy-to-understand change procedures to streamline the process

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Simplicity is a core SRE design principle. Google states: "Small, frequent, automated changes reduce risk and improve system stability." (SRE Book - Release Engineering). Automating continuous, small deployments creates a simple and repeatable pipeline that increases agility while maintaining reliability. This approach aligns with both DevOps and SRE practices: reducing deployment complexity, lowering blast radius, and supporting rapid iteration.
Option B best reflects this philosophy: automated, continuous small deployments provide simplicity, stability, and agility simultaneously.
Option A improves process clarity but does not directly affect agility.
Option C is beneficial but broader and not specific to simplicity.
Option D focuses on control rather than agility.
Thus, B is correct.
