Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. The CNCF/Linux Foundation offers this performance-based exam which targets the developer aspect of kubernetes skills such as deploying apps, configuring apps, rolling out the application, creating persistent volumes, etc.

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. This article helps you understand, practice and get you ready for the exam.

We are not going to discuss any concepts here, rather, I just want to create a bunch of practice questions for the CKAD exam based on the curriculum provided here.

• Core Concepts (13%)
• Multi-Container Pods (10%)
• Pod Design (20%)
• State Persistence (8%)
• Configuration (18%)
• Observability (18%)
• Services and Networking (13%)

4. List all the services in the particular namespace
