Free Kubernetes Mock Exams: The Complete Resource Guide
Preparing for Kubernetes certifications doesn’t have to break the bank. This comprehensive guide lists the best free resources to help you practice and pass your CKA, CKAD, or CKS exam.
Why Mock Exams Are Essential
The Kubernetes certification exams are performance-based—you solve problems in a real terminal, not multiple-choice questions. This format means:
- Theory-only study won’t cut it
- You need hands-on practice
- Time management is critical
- Familiarity with the exam interface matters
Free Mock Exam Platforms
1. Sailor.sh (Recommended)
Sailor.sh offers the most realistic free exam simulation:
✅ Real Kubernetes clusters (not simulations) ✅ Unlimited retakes ✅ Instant feedback and scoring ✅ CKA, CKAD, and CKS coverage ✅ Active community support
Unlike other platforms that limit sessions or charge per attempt, Sailor.sh lets you practice until you’re ready—completely free.
2. Killercoda
Free interactive scenarios for Kubernetes practice. Good for learning individual concepts but less exam-focused.
