Free PCA - Prometheus Certified Associate Exam Questions and Answers
PCA - Prometheus Certified Associate is one of the CNCF tests covered here. CNCF owns the curriculum but the exams are sold and proctored by Linux Foundation Training & Certification, taken online, and valid for two years. The mechanism splits sharply, and the name tells you which you are booking: an Associate exam such as KCNA or KCSA is multiple choice, while CKA, CKAD and CKS are performance-based — two hours at a real command line against a live cluster, with no multiple choice at all. Only one prerequisite is enforced anywhere in the programme: CKS requires a passed CKA. No pass mark is published for any of them.
The first 10 questions on this page are free to read, answers included — no account and no card. A plan opens the rest of the bank, the full timed practice test and your weak-topic reporting.
