Peoplecert PeopleCert DevOps Site Reliability Engineer (SRE) 認定 DevOps-SRE 試験問題 (Q42-Q47):

質問 # 42
Which of the following BEST describes the two key elements that an error budget balances?

正解：B

解説：
Comprehensive and Detailed Explanation From Exact Extract:
Error budgets represent the allowable amount of unreliability in a system. Google defines the purpose of error budgets as: "balancing the pace of innovation with the need for reliability." (SRE Book - Service Level Objectives). When the error budget is healthy, product teams can release features quickly; when it is exhausted, reliability work takes priority. This balance prevents over-investment in reliability and enables safe innovation.
Option B-innovation and reliability-is the exact phrasing used in Google's SRE literature.
Options A, C, and D do not reflect the core purpose of error budgets.
Thus, B is the correct answer.

質問 # 43
A bank has been using traditional monitoring tools for ensuring that their systems are available and operating as planned. Their strategic initiatives now include a renewed focus on customer experience as well as identifying ways to scale service.
Why would migrating to an observability approach be important now?

正解：D

解説：
Comprehensive and Detailed Explanation From Exact Extract:
All the listed reasons correctly describe why observability becomes essential in modern, user-focused, dynamically scaling architectures.
The SRE Workbook and Google Observability guidance both emphasize that traditional monitoring is insufficient in environments where:
* Services are distributed
* Traffic is unpredictable
* Customer experience is a priority
* Cloud-native, containerized, or microservice architectures are used
Key excerpts:
From Google's Observability guidance:
"Monitoring relies on known failure modes; observability enables teams to explore unknown-unknowns and understand complex, dynamic systems." From the SRE Workbook:
"As systems scale and architectures shift toward microservices or containers, component-level monitoring provides an incomplete picture. Observability enables teams to understand user impact and system behavior holistically." Thus:
* A Observability is critical for containerized and dynamic environments.
* B Component monitoring alone cannot show customer experience or end-to-end reliability.
* C Observability helps teams diagnose issues that could not be predicted in advance ("unknown unknowns").
All statements are correct, making D the correct answer.

質問 # 44
Which of the following BEST defines a Service Level Indicator (SLI)?

正解：D

解説：
Comprehensive and Detailed Explanation From Exact Extract:
Google's definition is explicit: "An SLI is a carefully defined QUANTITATIVE measure of some aspect of the level of service provided." (SRE Book - Chapter: Service Level Objectives). Examples include error rate, latency, throughput, and availability. SLIs are measurements, not targets-targets are SLOs.
Option D repeats Google's definition almost exactly.
Option C incorrectly describes an SLO (a target), not an SLI.
Options A and B mention subjective assessments-SRE explicitly rejects subjectivity in measurement, stating: "SLIs must be objective and measurable." Thus, D is the correct and SRE-authentic answer.

Site Reliability Engineering, Chapter: "Service Level Objectives."
The Site Reliability Workbook, Chapter: "Implementing SLOs."


質問 # 45
A team has exceeded their error budget by 10% in a particular month.
Give an example of what should happen next as a consequence.

正解：C

解説：
Comprehensive and Detailed Explanation From Exact Extract:
When a team exceeds its error budget, SRE practice requires applying error budget policies that restrict feature releases and shift focus toward reliability improvement. The idea is to prevent further degradation of user experience and ensure the service meets the agreed reliability targets.
The Site Reliability Engineering Book, Chapter "Service Level Objectives," states:
"If the service exceeds its error budget, all new feature launches or risky changes are halted until reliability returns to acceptable levels. Engineering work should be directed toward addressing the causes of the budget overrun." This aligns with option A, which describes a reliability-focused response during sprint planning. Limiting sprint planning to post-mortem action items and reliability improvements is a direct application of error budget policies.
Additional guidance from the SRE Workbook:
"Error budget burn should directly influence decision-making. When the budget is exhausted, the team must focus on remediation work rather than new features." Why the other options are incorrect:
* B Reviewing the error budget's realism can be done periodically, but it is not the immediate consequence of a breach.
* C Extending the error budget invalidates its purpose and is discouraged.
* D Ignoring the error budget contradicts the entire SRE model and Google's official guidance.
Therefore, A is the only correct answer.
