Free Professional Cloud DevOps Engineer sample questions

1. A cloud DevOps engineer is validating sre principles and service reliability for GCP DevOps Engineer and must balance release velocity with reliability targets. Which response is the BEST fit?

   • A. Define user-focused SLIs and SLOs before using error budgets to guide release decisions
   • B. Use CPU utilization as the only user-facing reliability metric
   • C. Ignore error-budget burn because the release date is fixed
   • D. Automate a broken manual process without understanding failure modes
   Show answer

   Correct: A. Define user-focused SLIs and SLOs before using error budgets to guide release decisions is the best answer because SRE decisions use SLOs, SLIs, error budgets and toil reduction to guide release and operations choices. The other choices do not fit the scenario: Use CPU utilization as the only user-facing reliability metric addresses the wrong layer or timing, Ignore error-budget burn because the release date is fixed skips a required control, and Automate a broken manual process without understanding failure modes would create avoidable operational or security risk.

2. During a production rollout, a cloud devops engineer needs to handle frequent deployments causing error-budget burn without weakening sre principles and service reliability. Which response is the BEST fit?

   • A. Pause or slow risky launches when error-budget burn exceeds the agreed threshold
   • B. Ignore error-budget burn because the release date is fixed
   • C. Automate a broken manual process without understanding failure modes
   • D. Let engineering change SLOs without business agreement
   Show answer

   Correct: A. Pause or slow risky launches when error-budget burn exceeds the agreed threshold is the best answer because SRE decisions use SLOs, SLIs, error budgets and toil reduction to guide release and operations choices. The other choices do not fit the scenario: Ignore error-budget burn because the release date is fixed addresses the wrong layer or timing, Automate a broken manual process without understanding failure modes skips a required control, and Let engineering change SLOs without business agreement would create avoidable operational or security risk.

3. A review board asks for two actions that support balance release velocity with reliability targets while reducing shipping changes that violate user-facing reliability commitments. Which TWO choices should the engineer select? (Choose TWO)

   • A. Define user-focused SLIs and SLOs before using error budgets to guide release decisions
   • B. Reduce toil with automation for repeatable operational tasks
   • C. Use CPU utilization as the only user-facing reliability metric
   • D. Let engineering change SLOs without business agreement
   Show answer

   Correct: A and B. Define user-focused SLIs and SLOs before using error budgets to guide release decisions and Reduce toil with automation for repeatable operational tasks are correct because SRE decisions use SLOs, SLIs, error budgets and toil reduction to guide release and operations choices. The distractors do not satisfy the requirement: Use CPU utilization as the only user-facing reliability metric is incomplete for this case, and Let engineering change SLOs without business agreement solves a different problem or weakens the design.

4. An audit finding shows shipping changes that violate user-facing reliability commitments in sre principles and service reliability for a regulated production environment. Which response is the BEST fit?

   • A. Reduce toil with automation for repeatable operational tasks
   • B. Automate a broken manual process without understanding failure modes
   • C. Let engineering change SLOs without business agreement
   • D. Use CPU utilization as the only user-facing reliability metric
   Show answer

   Correct: A. Reduce toil with automation for repeatable operational tasks is the best answer because SRE decisions use SLOs, SLIs, error budgets and toil reduction to guide release and operations choices. The other choices do not fit the scenario: Automate a broken manual process without understanding failure modes addresses the wrong layer or timing, Let engineering change SLOs without business agreement skips a required control, and Use CPU utilization as the only user-facing reliability metric would create avoidable operational or security risk.

5. A team is preparing a change window for sre principles and service reliability and needs defensible evidence for exam-style review. Which response is the BEST fit?

   • A. Review reliability data with product owners before changing SLO targets
   • B. Let engineering change SLOs without business agreement
   • C. Use CPU utilization as the only user-facing reliability metric
   • D. Ignore error-budget burn because the release date is fixed
   Show answer

   Correct: A. Review reliability data with product owners before changing SLO targets is the best answer because SRE decisions use SLOs, SLIs, error budgets and toil reduction to guide release and operations choices. The other choices do not fit the scenario: Let engineering change SLOs without business agreement addresses the wrong layer or timing, Use CPU utilization as the only user-facing reliability metric skips a required control, and Ignore error-budget burn because the release date is fixed would create avoidable operational or security risk.
