We answer hypothetical questions that may appear on the Certified Kubernetes Application Developer (CKAD) exam.

While doing some work with Kubernetes (K8s) and studying for the CKAD exam, I came across a page on Matthew Palmer’s website entitled “Practice Exam for Certified Kubernetes Application Developer (CKAD) Certification” and which contains five practice questions, which I’ll go over here. If you see a problem with anything I’ve done below, including inefficient solutions, please let me know in the comments.

We will focus on not just showing a possible solution to each problem but also verifying our work.

Since we’re limited to the kubernetes.io website when taking this test, this site is referenced where appropriate — in particular the kubectl cheat sheet page is not a bad place to start and we can search for what we need here as well.

Lastly, with each of these questions, we need to pay particular attention to the namespace requirement.

This article relies on minikube running on Ubuntu along with the Oh My Zsh shell.

The k command is defined as follows:

alias k='kubectl'

Let’s take a look at the first question.
