Free PCA practice test — 304+ PCA practice questions with detailed explanations across all 5 official PCA exam domains. Every set is scored and drawn from the live question bank — so you practise exactly what the exam tests, not outdated dumps.
Courseiva includes 304+ Prometheus Certified Associate (PCA, CNCF/Linux Foundation) (PCA) practice questions across the official exam domains.
Feature
Courseiva
This free PCA practice test mirrors the structure and difficulty of the real Prometheus Certified Associate (PCA, CNCF/Linux Foundation) (PCA) exam. Every question is written against the official 2026 exam blueprint published by CNCF / Linux Foundation, ensuring you practise exactly what the exam tests — not last year's objectives.
The PCA blueprint is divided into 5weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like Observability Concepts and Prometheus Fundamentals contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.

23 numbered sets, 5 domain question banks, and targeted sessions — every page is a unique set of questions.
Choose all correct answers
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass PCA on their first attempt:
Answer before revealing
Read each PCA question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which PCA domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real PCA gives you roughly 0.6 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass PCA on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 304+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.

A structured study plan dramatically increases your chances of passing PCA on the first attempt. The most effective approach combines reading the official CNCF / Linux Foundation documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for PCA preparation:
Cover each PCA domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing PCA score.
On exam day, the PCA tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.
The real exam is entirely performance-based — there are no multiple-choice questions. Courseiva questions reinforce concepts, but hands-on lab practice is still required.

Every question is written against the official PCA exam objectives published by CNCF / Linux Foundation. They focus on the concepts and knowledge areas tested in the performance-based exam. These are original questions — not brain dumps — written to make you competent, not just exam-day lucky. Note that the real PCA is a hands-on lab exam; these questions prepare your knowledge but hands-on practice is also required.
Most candidates who pass PCA on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The PCA covers 5 domains: Observability Concepts, Prometheus Fundamentals, Alerting And Dashboarding, Promql, Instrumentation And Exporters. Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Observability Concepts and Prometheus Fundamentals — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without CNCF / Linux Foundation's authorisation. Using them violates your NDA and CNCF / Linux Foundation's certification agreement, and can result in certification revocation. Courseiva questions are 100% original — written by certified engineers to test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
Per-domain analytics, spaced repetition, daily challenges — and every other certification on the platform.
