Frequently asked questions

How long is the CKAD exam and what does it cost?

2 hours, $445. Online proctored, performance-based, solved entirely at a command line. The certification stays valid for 2 years.

What is on the CKAD exam?

5 domains. The heaviest is Application Environment, Configuration and Security at 25% of the exam, so it is the one worth over-preparing.

What should I know before starting CKAD?

Building and running containers day to day. Reading and editing YAML quickly. One programming language well enough to debug a running service.

Is the CKAD exam hands-on?

Yes. It is performance-based: you are given a live environment and a command line, and marked on what you actually do rather than what you can recognise. Reading alone does not prepare you for it.
