SRE practice questions - frequently asked questions

Plain answers about how SRE Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real SRE exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The SRE exam spans 7 domains: SRE Principles and Practices (20% of the exam); Service Level Objectives (16% of the exam); Toil and Automation (12% of the exam); Monitoring and Observability (12% of the exam); Release Engineering and Change Management (12% of the exam); Anti-Fragility and Learning from Failure (16% of the exam); Organizational Impact of SRE (12% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: SRE Principles and Practices 20%; Service Level Objectives 16%; Anti-Fragility and Learning from Failure 16%; Toil and Automation 12%; Monitoring and Observability 12%; Release Engineering and Change Management 12%; Organizational Impact of SRE 12%.

The SRE exam has 40 questions and is completed in 1 hour. Our timed practice mirrors that length and pacing, so exam day feels familiar.
