Who It Is For
Is CKAD the right fit for you?
CKAD suits application developers, DevOps engineers and platform teams who design, ship and debug apps that run on Kubernetes. The Linux Foundation says the exam assumes working knowledge of container runtimes and microservice architecture, so you'll get the most from it if you've already built and run containers.
There are no prerequisites, so you can register whenever you're ready. The Linux Foundation lists the experience level as Intermediate.
Exam Format
CKAD 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 LFD259 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 CKAD.
We start with Application Design and Build. It's 20% of the exam, so we cover its 4 competencies with hands-on labs on a live cluster.
Next we cover Application Deployment. It's 20% of the exam, so we cover its 4 competencies with hands-on labs on a live cluster.
Then we move to Application Observability and Maintenance. It's 15% of the exam, so we cover its 5 competencies with hands-on labs on a live cluster.
After that comes Application Environment, Configuration and Security. 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 and Networking. It's 20% of the exam, so we cover its 3 competencies with hands-on labs on a live cluster.
Application Environment, Configuration and Security carries the most weight at 25%, 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 CKAD.
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.
Career Outlook
Where CKAD can take you.
CKAD is aimed at developers and DevOps engineers who ship apps on Kubernetes. 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 software developers, quality assurance analysts and testers at $134,040. A median is the midpoint, so half earned more and half earned less, and your own pay will depend on location, experience and employer. Source: BLS Occupational Outlook Handbook.
