CKA Exam FAQs for 2026 Candidates
Which certification does the CKA exam lead to?
The CKA exam is the official Linux Foundation / Cloud Native Computing Foundation (CNCF) exam behind the Certified Kubernetes Administrator (CKA) certification, validating the skills measured by the Linux Foundation Certified Kubernetes Administrator (CKA) Program credential. It sits at the Professional level of the Linux Foundation / Cloud Native Computing Foundation (CNCF) certification program. It also connects to Certified Kubernetes Application Developer (CKAD), Certified Kubernetes Security Specialist (CKS), so the knowledge you build here carries over to those tracks as well.
How many questions are on the CKA exam, and how much time do I get?
The CKA exam contains 15-20 performance-based tasks questions to be completed within 120 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.
What score do I need to pass the CKA exam, and what does it cost?
The passing score for the CKA exam is 66%, and the official registration fee is $445 USD. Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 85 practice questions on Getcertkey, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

Linux Foundation Certified Kubernetes Administrator (CKA) Program Sample Questions:
Question 1
Create a namespace called 'development' and a pod with image nginx called nginx on this namespace.
Question 2
List "nginx-dev" and "nginx-prod" pod and delete those pods
Question 3
You must connect to the correct host.
Failure to do so may result in a zero score.
[candidate@base] $ ssh Cka000037
Context
A legacy app needs to be integrated into the Kubernetes built-in logging architecture (i.e.
kubectl logs). Adding a streaming co-located container is a good and common way to accomplish this requirement.
Task
Update the existing Deployment synergy-leverager, adding a co-located container named sidecar using the busybox:stable image to the existing Pod . The new co-located container has to run the following command:
/bin/sh -c "tail -n+1 -f /var/log/syne
rgy-leverager.log"
Use a Volume mounted at /var/log to make the log file synergy-leverager.log available to the co- located container .
Do not modify the specification of the existing container other than adding the required volume mount .
Failure to do so may result in a reduced score.
Question 4
List pod logs named "frontend" and search for the pattern "started" and write it to a file "/opt/error-logs" See the solution below.
Question 5
Score: 4%
Task
Create a persistent volume with name app-data , of capacity 1Gi and access mode ReadOnlyMany. The type of volume is hostPath and its location is /srv/app-data .
