Question 26

Which of the following BEST describes the relationship between Service Level Objectives and Service Level Indicators?

Correct Answer: A
Comprehensive and Detailed Explanation From Exact Extract:
The SRE Book provides a precise definition: "SLIs are the carefully defined quantitative measures of some aspect of the level of service provided. SLOs are the target values or ranges for these indicators." (SRE Book
- Chapter: Service Level Objectives). This establishes a clear hierarchical relationship: SLIs are the measurements, while SLOs define the acceptable target levels for those measurements.
Therefore, option A is correct: SLIs measure things like latency, availability, throughput, and error rate.
SLOs then define the goal such as "99.9% availability over 30 days."
Option B reverses the relationship.
Option C incorrectly says SLOs measure SLIs, which is backwards.
Option D confuses metrics and targets.
Thus, A is the only choice that aligns with Google's official SRE definitions.

Question 27

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

Correct Answer: B
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.

Question 29

Which of the following BEST describes how to contribute to achieving higher levels of availability?
* Measuring the critical aspects
* Maintaining a close relationship with development teams
* Measuring staff performance
* Maintaining a close interval between detection and correction

Correct Answer: D
Comprehensive and Detailed Explanation From Exact Extract:
Achieving high availability in SRE practice is driven by accurate measurement of what matters and fast detection and correction of issues. According to Google's Site Reliability Engineering Book, measurement of critical user-facing signals is foundational: "SLIs must capture the aspects of the service that are most critical to users and must be measured with high accuracy." (SRE Book - Chapter: Service Level Objectives).
Without measuring the critical aspects of a service-latency, errors, availability, and quality-teams cannot make informed decisions or detect degradation effectively.
The SRE book also emphasizes reducing MTTR (Mean Time to Repair) and tightening the feedback loop between detection and correction. Google states: "Reducing the time between detection and mitigation is one of the most effective levers for improving availability." (SRE Book - Chapters on Incident Response & Monitoring). Rapid identification and resolution directly improve a system's availability and resilience.
Option D (1 and 4) is the only choice that correctly reflects SRE principles.
* Measuring critical aspects # essential for correct SLO/SLI alignment
* Maintaining a short interval between detection and correction # drives higher availability Options including staff performance measurement or generic development relationships are not mentioned as availability-driving factors in the SRE literature.
