Who It Is For
Is CKA the right fit for you?
CKA suits Kubernetes administrators, platform and infrastructure engineers, site reliability engineers and systems administrators who build, run and repair clusters. If you already work at the Linux command line and want proof you can keep a cluster healthy under pressure, this is the one.
There are no prerequisites, so you can register whenever you're ready. The Linux Foundation lists the experience level as Intermediate.
Exam Format
CKA at a glance.
Exam details
- Format: online, proctored, performance-based
- Tasks: solved at the command line
- Length: 2 hours
- Passing score: 66%
- Kubernetes version: v1.37
- Languages: English, Simplified Chinese and Japanese
- Exam only: $445
- With THRIVE-ONE: $625
- With the LFS258 course: $645
- Includes: 12 months to take the exam, two Killer.sh simulator attempts and one retake
- Validity: 2 years
There are no multiple choice questions. You work live tasks against real clusters at the command line, and the result arrives by email within 24 hours.
The Linux Foundation says the exam environment aligns with the most recent Kubernetes minor version within about 4 to 8 weeks of its release. Each Killer.sh simulator attempt gives you 36 hours of access and 17 questions, and we tell students to save one for the final week. Speed with kubectl, imperative commands and the official docs is what decides most outcomes in our experience.
Study Plan
How we prepare you for CKA.
We start with Storage. It's 10% of the exam, so we cover its 3 competencies with hands-on labs on a live cluster.
Next we cover Troubleshooting. It's 30% of the exam, so we cover its 5 competencies with hands-on labs on a live cluster.
Then we move to Workloads & Scheduling. It's 15% of the exam, so we cover its 5 competencies with hands-on labs on a live cluster.
After that comes Cluster Architecture, Installation & Configuration. It's 25% of the exam, so we cover its 8 competencies with hands-on labs on a live cluster.
We wrap up with Services & Networking. It's 20% of the exam, so we cover its 6 competencies with hands-on labs on a live cluster.
Troubleshooting carries the most weight at 30%, so it gets the most review time. In the last week we run timed mock tasks, use a Killer.sh session and drill your weakest domains until the commands are second nature.
Exam Policies
Retakes, proctoring and renewal for CKA.
Your purchase includes one retake, and you have 12 months from purchase to schedule and sit the exam.
The exam is proctored by PSI through the PSI Secure Browser on the Bridge platform. Only one monitor is allowed, the Linux Foundation recommends a personal device over a work machine, and the name on your ID must match your registration exactly.
Certifications are valid for 2 years. You renew by passing the exam again before your certification expires.
Under the CARE program, earning CKS on or after June 18, 2026 extends your CKA.
Career Outlook
Where CKA can take you.
CKA is aimed at Kubernetes administrators, platform engineers and SREs. BLS doesn't track Kubernetes roles separately, so we use the closest occupation as a reference.
For a sense of pay, BLS puts the May 2025 median annual wage for network and computer systems administrators at $99,130. That figure is a national midpoint. Where you live, how long you have been in the field and who you work for all move the number. Source: BLS Occupational Outlook Handbook.
