Common Questions About the Linux Foundation PCA Exam
The PCA exam, officially known as Linux Foundation Prometheus Certified Associate, is the Linux Foundation test that leads to the Cloud & Containers certification at the Intermediate level. Passing it validates the skills employers expect from a certified professional. It is also associated with related credentials such as CKA (Kubernetes Administrator), CKAD (Kubernetes Application Developer), KCNA (Kubernetes and Cloud Native Associate).
The PCA exam contains 65 questions, and you have 90 minutes to complete them. Work out your per-question pace before test day, and flag slow items instead of stalling on them — time pressure, not knowledge, sinks many first attempts. Timed mock exams in the Actual4Exams test engines are the most reliable way to build that rhythm.
The passing score for the PCA exam is 70%, and the official registration fee is $250 USD. If you miss the mark, a retake means paying the full fee again, so book your seat only when you are ready. A practical benchmark: score consistently above the passing line on timed practice tests before scheduling the real exam.
Basic understanding of Linux, command-line, and general monitoring concepts recommended. Familiarity with Kubernetes is helpful but not required.
