Since this exam is performance-based rather than just multiple choice questions just knowing the concepts are not enough, we need a lot of practice before the exam.

These 150 questions give you enough practice for the exam. The more you practice the more comfortable you feel during the exam.

In order to practice, you need to have a valid Kubernetes cluster setup. There are multiple ways to spin up a Kubernetes cluster free of cost:

1. Setup Kubernetes Cluster using minikube.

2. Create Kubernetes Cluster using GKE which gives you $300 credit.

3. Create Kubernetes Cluster on AWS using free tier.
