CKAD Exam Overview: What to Expect

Okay, let's talk about the exam itself. The CKAD exam is a hands-on, performance-based test. This means you'll be working directly with a Kubernetes cluster and completing tasks in a live environment. There's no multiple-choice here, folks! You'll be presented with a series of challenges that require you to demonstrate your practical Kubernetes skills.

The exam is designed to take about 2 hours, and you'll have access to the official Kubernetes documentation during the exam. This is a huge help, but don't get too comfortable relying on it! You'll still need to have a solid understanding of the concepts and be able to apply them quickly and efficiently.

The exam covers a wide range of topics, including:

• Core Concepts: Pods, deployments, services, namespaces, etc. This is the foundation, so make sure you have a firm grasp of these basics.
• Configuration: YAML configuration files are your best friends here! You'll need to know how to create, modify, and manage Kubernetes resources using YAML.
• Networking: Understanding how Kubernetes networking works is crucial. You'll need to know how to configure services, ingress, and network policies.
• Storage: Persistent volumes, persistent volume claims, and storage classes are all important. You'll need to know how to manage storage for your applications.
• Application Design and Deployment: This is where you'll apply your knowledge to deploy and manage applications in Kubernetes. You'll be working with deployments, replica sets, and other deployment strategies.
• Troubleshooting: Be prepared to troubleshoot common Kubernetes issues. You'll need to be able to identify and resolve problems quickly and efficiently.

Exam Format and Structure

The CKAD exam consists of a series of tasks, each weighted differently. The weights are usually indicated in the exam instructions. This means that some tasks are worth more points than others, so it's important to allocate your time wisely. Make sure you read the instructions carefully for each task and understand what's expected of you.

The exam is proctored online, so you'll need a stable internet connection and a quiet environment. You'll also need a webcam and a microphone. The proctor will monitor you throughout the exam to ensure that you're following the rules.
