How CertGrid questions are reviewed
Every bank is written and maintained by our team against the vendor's current skills outline - not copied or scraped from exam content. Each question is mapped to a published concept, every answer carries an explanation covering why the right option is right and why each wrong option is wrong, and banks are re-reviewed whenever the exam changes. Individual exam pages show the date each bank was last reviewed.
Frequently asked questions
Which Kubernetes exam should I take first?
KCNA (Kubernetes and Cloud Native Associate) is the beginner-friendly entry point. CKA (Certified Kubernetes Administrator) is the most popular hands-on certification, with CKAD and CKS building on it.
Are these official CNCF exam questions?
No. CertGrid is an independent practice platform. We do not provide real or leaked exam questions. Our questions are original and designed to help you practice the concepts, scenarios, and difficulty style of the Kubernetes and cloud native exams.
Are the CKA, CKAD and CKS exams hands-on?
The real CKA, CKAD and CKS are performance-based (you work in a live cluster). Our questions build the underlying knowledge - commands, resources, and troubleshooting patterns - that the hands-on tasks assume, alongside the knowledge-based KCNA and KCSA.
Can I practice for free?
Yes. Free users get 20 practice questions per day from a fixed sample question pool for each exam, with basic explanations. Pro unlocks the full question bank, complete explanations, and timed mock exams across every Kubernetes bank.
How long are CKA, CKAD and CKS certifications valid?
Kubernetes and cloud native certifications purchased from CNCF are valid for two years from your pass date, after which you retake the then-current version of the exam to renew.
Is there a retake policy for CNCF exams?
Yes. Each CNCF exam registration includes one free retake if you do not pass on your first attempt, and you can purchase additional attempts separately after that.
