Peoplecert PeopleCert DevOps Site Reliability Engineer (SRE) Sample Questions (Q12-Q17):

NEW QUESTION # 12
Why would some Service Level Indicators require client-side data?

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
SLIs must measure user experience, and sometimes server-side metrics alone do not show the full picture.
Client-side data may reveal issues such as:
* Slow networks
* Browser rendering delays
* Mobile device limitations
* CDN performance issues
* Last-mile latency
The Site Reliability Engineering Book, Chapter "Service Level Indicators," states:
"Server-side metrics do not always fully capture the user experience. In many cases, client-side measurements are required to understand the actual reliability delivered to users." The SRE Workbook reinforces:
"Some SLIs require client instrumentation because user-visible performance problems may not be observable from backend systems alone." Why the other options are incorrect:
* B SLA negotiation has nothing to do with SLI selection.
* C Automation engineering is unrelated to client-side measurement needs.
* D Achievability of SLOs does not determine whether client-side data is needed; accuracy of user- experience measurement does.
Thus, the correct answer is A.

SRE Workbook, "Choosing the Right SLIs"


NEW QUESTION # 13
Who codifies software-defined networks (SDNs) and applies SDLC principles to build, test and deploy network changes?

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
A Network Reliability Engineer (NRE) is a specialized reliability role focused on applying SRE practices to networking. They use software engineering, SDLC concepts, and automation to manage networks at scale, including SDNs.
Google describes NRE as:
"Network Reliability Engineering applies SRE principles to network management, treating network configuration as code and automating changes safely."
- Google Reliability Engineering Guidance
Responsibilities include:
* Codifying SDN configurations
* Automating network deployment
* Testing network changes through CI/CD
* Reducing network-related outages
Thus, the correct answer is B.

Google Cloud: "Network Reliability Engineering"
SRE principles applied to network automation


NEW QUESTION # 14
The value of data-driven measurements can be MOST accurately explained by which of the following?

Answer: C


NEW QUESTION # 15
Service Level Indicator data helps to understand how much Error Budget is left.
TRUE or FALSE?

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Service Level Indicators (SLIs) provide the quantitative measurements needed to determine how much of the Service Level Objective (SLO) has been consumed. Since the error budget is defined as the allowable amount of unreliability, SLI data is the source of truth for calculating how much of that budget remains.
From the Site Reliability Engineering Book, Chapter "Service Level Objectives":
"SLIs provide the measurements used to determine compliance with SLOs. Error budgets are computed directly from the SLI measurements over the defined time window." The SRE Workbook further explains:
"Error budgets quantify the inverse of SLO performance. SLIs provide the raw data that allow teams to calculate how much of the budget has been consumed and how much remains." Thus, SLI data is the Only mechanism that determines remaining error budget.
Therefore, the statement is True.

SRE Workbook, "Implementing SLIs and SLOs"


NEW QUESTION # 16
What does the Westrum model study?

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The Westrum Organizational Culture Model categorizes organizations based on how effectively they allow information to flow, particularly in high-risk and high-performance environments. This model is widely referenced in SRE and DevOps practices and is cited by Google in their SRE culture guidance.
The Westrum model identifies three culture types:
* Pathological (power-oriented)
* Bureaucratic (rule-oriented)
* Generative (performance-oriented)
From the SRE Workbook and Google's DevOps Research (DORA):
"The Westrum model is a taxonomy of organizational cultures based on how information flows. Generative cultures-with high cooperation and open information flow-correlate with higher reliability and better outcomes." Why the other options are incorrect:
* A Deployment frequency is a DORA metric, not Westrum's focus.
* C Resource flow is unrelated to Westrum.
* D While communication affects design, Westrum specifically studies information flow as a cultural health indicator, not structural design.
Thus, the correct answer is B.
