Question 1

What is the CKA exam?

Accepted Answer

The CKA (Certified Kubernetes Administrator) is a performance-based certification offered by the Linux Foundation and the CNCF. It validates that you have the skills and knowledge to perform the responsibilities of a Kubernetes administrator. The certification is widely recognised by employers and is considered one of the leading credentials in cloud-native infrastructure.

Question 2

How many questions are on the CKA exam?

Accepted Answer

The CKA exam consists of 15 to 20 performance-based tasks that must be completed within a two-hour time limit. Unlike multiple-choice tests, you work directly in a live Kubernetes environment using a terminal, completing tasks such as creating deployments, configuring RBAC, setting up network policies, and troubleshooting cluster issues.

Question 3

What is the passing score for the CKA?

Accepted Answer

The passing score for the CKA exam is 66%. Results are typically provided within 24 hours of completing the exam. If you do not pass on your first attempt, you are entitled to one free retake included with your exam registration.

Question 4

Is the CKA exam multiple choice?

Accepted Answer

No — the CKA is a hands-on, practical exam conducted entirely in a live terminal environment. You are given access to multiple Kubernetes clusters and must complete real administrative tasks. This makes thorough practical preparation essential, which is why working through scenario-based practice questions is so valuable.

Question 5

What topics does the CKA cover?

Accepted Answer

The CKA covers five domains: Cluster Architecture, Installation and Configuration; Workloads and Scheduling; Services and Networking; Storage; and Troubleshooting. Troubleshooting is the highest-weighted domain at 30%, covering tasks such as diagnosing broken cluster components, debugging application failures, and restoring etcd from backups.

Question 6

Can I use Kubernetes documentation during the CKA exam?

Accepted Answer

Yes — during the CKA exam you are permitted to use the official Kubernetes documentation at kubernetes.io. However, the time pressure means that knowing where to find information quickly is just as important as knowing the content itself. Practising with the documentation open alongside these mock questions is an effective preparation strategy.
