Question 1

What is the Certified Kubernetes Administrator (CKA) exam?

Accepted Answer

The Certified Kubernetes Administrator (CKA) is a performance-based certification from the Cloud Native Computing Foundation (CNCF) and Linux Foundation. It validates the skills required to be a Kubernetes administrator in production environments, covering cluster architecture, networking, storage, workloads, scheduling, and troubleshooting. About 100,000 candidates sit the exam each year.

Question 2

How many questions are on the CKA exam?

Accepted Answer

The CKA exam consists of 15-20 performance-based tasks (not multiple-choice) to be completed in 2 hours in a live Kubernetes environment. Candidates must complete real kubectl commands and YAML configurations in an actual cluster. There is no multiple-choice component.

Question 3

What is the pass rate for the CKA?

Accepted Answer

The estimated first-attempt pass rate for CKA is approximately 66%. The hands-on nature of the exam is the main differentiator from traditional certifications. Candidates who practise in real Kubernetes environments and can work efficiently under time pressure pass at much higher rates.

Question 4

How long does it take to prepare for the CKA?

Accepted Answer

Most candidates need 60-120 hours over 2-3 months. Hands-on Kubernetes practice is essential - setting up local clusters with minikube or kind, and practicing with killer.sh or Kubernetes playground environments. Knowing how to navigate the official Kubernetes documentation quickly is also a key skill for the open-book exam.

Question 5

What score do I need to pass the CKA?

Accepted Answer

The passing score for CKA is 66%. Each task is worth a percentage of the total score. Practising all task categories - especially the lower-scoring but time-intensive ones - and building speed and accuracy with kubectl and YAML is the key to achieving 66%+ on exam day.
