Site Reliability Engineering Foundation Mock Exam

Updated on 10 October 2026. What’s new: exam fee corrected to $257 and the vendor's page lists the exam as open book, not closed book

If you carry a pager for servers someone else designed, a credential will not make you an SRE, but it can show a hiring manager that you already speak the language: service level objectives, error budgets, toil, blameless reviews. SRE Foundation from DevOps Institute is the entry paper for that language. It has 40 questions, runs 60 minutes, needs 65% and costs $257, and this guide explains what it is worth to your career and how to prepare for it.

DevOps Institute, which created the exam, is now part of the PeopleCert group. The vendor's exam page says so in a footnote, and its purchase button hands you over to PeopleCert's platform to pay. I read both the DevOps Institute page and PeopleCert's listing in October 2026. The exam is still on sale, and neither page shows a version number, so there is no newer edition to chase.

What does this credential tell a hiring manager about an ops engineer?

It tells them three modest things. First, that you have studied the vocabulary of reliability work in a structured way rather than picking it up from incident chatter. Second, that you can separate ideas that sound alike, such as an indicator, an objective and an agreement. Third, that you chose to spend evenings on this instead of waiting for your employer to send you on a course.
