Site Reliability Engineering (SRE) Principles
Q1. A global e-commerce application hosted on Google Cloud experiences periodic
latency spikes during promotional campaigns. The organization wants to prioritize
reliability investments based on customer impact rather than infrastructure metrics.
Which approach best aligns with Site Reliability Engineering principles?
A. Monitor CPU utilization across all instances and scale when utilization exceeds
50%
B. Define user-centric Service Level Indicators and establish Service Level Objectives
tied to business outcomes
C. Increase infrastructure redundancy in all regions regardless of service criticality
D. Focus exclusively on reducing infrastructure costs
Correct Answer: 🔴 B. Define user-centric Service Level Indicators and establish
Service Level Objectives tied to business outcomes
Explanation: 🔹 SRE emphasizes measuring reliability from the user's perspective.
SLIs and SLOs provide quantifiable measures of service quality that align technical
operations with business expectations. CPU utilization alone may not reflect user
experience, blanket redundancy can waste resources, and focusing solely on cost
ignores reliability objectives.
Q2. An SRE team notices engineers spend nearly all their time handling operational
tasks, leaving little opportunity for automation. According to SRE best practices, what
should be the primary recommendation?
A. Increase manual review processes
B. Hire additional operators indefinitely
C. Invest in reducing toil through automation and engineering improvements
D. Eliminate monitoring alerts
,Correct Answer: 🔴 C. Invest in reducing toil through automation and engineering
improvements
Explanation: 🔹 Toil refers to repetitive, manual operational work. SRE practices
advocate eliminating toil through automation to improve scalability and
engineering efficiency. Additional staffing without automation often increases
operational complexity while failing to solve underlying inefficiencies.
Q3. Your organization wants to balance innovation speed and service reliability.
Which SRE concept directly supports this balance?
A. Error budgets
B. Static infrastructure allocation
C. Manual deployment approvals only
D. Infrastructure lock-in
Correct Answer: 🔴 A. Error budgets
Explanation: 🔹 Error budgets quantify acceptable unreliability and help teams
balance feature velocity with reliability requirements. If reliability remains within
budget, teams can release rapidly; when budgets are exhausted, reliability
improvements take priority. Other options do not provide measurable governance
between innovation and stability.
Q4. A service achieves 99.95% availability over six months. The agreed SLO is 99.90%.
What conclusion should the DevOps team draw?
A. The service violated its SLO
B. Reliability targets were exceeded and error budget remains available
C. Monitoring data is invalid
D. Releases must be frozen
Correct Answer: 🔴 B. Reliability targets were exceeded and error budget remains
available
, Explanation: 🔹 Since actual performance exceeds the defined SLO, the service
remains within acceptable reliability limits. The remaining error budget can
support continued feature development and deployment activities.
Q5. Which activity is considered toil in an SRE environment?
A. Designing automated deployment pipelines
B. Conducting architecture reviews
C. Repeatedly restarting failed services using identical procedures
D. Implementing observability improvements
Correct Answer: 🔴 C. Repeatedly restarting failed services using identical
procedures
Explanation: 🔹 Toil consists of repetitive, automatable work with limited long-term
value. Repeated service restarts fit this definition and should be automated
whenever feasible. The other activities contribute strategic engineering value.
Q6. A company wants to improve operational maturity. Which metric best indicates
successful SRE adoption?
A. Number of physical servers deployed
B. Percentage of operational tasks automated
C. Number of spreadsheets maintained
D. Quantity of daily meetings
Correct Answer: 🔴 B. Percentage of operational tasks automated
Explanation: 🔹 Effective SRE implementations reduce manual operational effort
through automation. Automation rates indicate progress toward scalable
operations, whereas server counts, spreadsheets, and meetings provide little insight
into reliability engineering maturity.
