Domain percentage weights are not currently available for this exam. The checklist below is still useful for planning your study.
Performance-based exam
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.
Phase 1
Promql
Tip: Start with the official Promql objectives, then practise questions on it.
Phase 2
Prometheus Fundamentals
Tip: Cover the Prometheus Fundamentals objectives, then answer practice questions to confirm you can apply them.
Phase 3
Observability Concepts
Tip: Cover the Observability Concepts objectives, then answer practice questions to confirm you can apply them.
Phase 4
Alerting And Dashboarding
Tip: Cover the Alerting And Dashboarding objectives, then answer practice questions to confirm you can apply them.
Phase 5
Instrumentation And Exporters
Tip: Finish with Instrumentation And Exporters, then re-test your weakest earlier domain before a mock exam.
Study the official exam blueprint — weight percentages tell you exactly where to invest prep time.
Practise scenario-based questions regularly — every modern cert exam is scenario-heavy.
Use spaced repetition to retain what you've learned (Courseiva does this automatically).
Book your exam date once you're scoring 80%+ consistently on practice tests.
Review explanations for every wrong answer, not just the question — the 'why' is what makes it stick.
Apply everything in this guide with adaptive practice questions, detailed answer explanations, and domain analytics.
