Comparing to CKAD, what additional topics should I focus on CKA?

Hi there,

Congratulations on passing the CKAD exam! Since you're transitioning to the Certified Kubernetes Administrator (CKA) level, there are a few areas you might want to focus on:

Cluster Setup and Configuration: Make sure you are comfortable setting up a Kubernetes cluster from scratch, including configuring various components and network settings.

Security Best Practices: Dive into Kubernetes security concepts, such as RBAC, Network Policies, and secrets management. Understanding how to secure your cluster is crucial for the CKA exam.

Cluster Maintenance: Learn about cluster upgrades, backup and restore procedures, and troubleshooting common issues. Practical experience in keeping a cluster healthy is important.

Advanced Networking: Deepen your knowledge of Kubernetes networking, including Service types, DNS configuration, and Ingress controllers.

Storage Management: Explore how to manage persistent storage in Kubernetes, including different storage classes, PVs, and PVCs.

Resource Management: Understand how to allocate resources to pods effectively, including CPU and memory management, and deal with resource constraints.

Cluster Monitoring and Logging: Familiarize yourself with monitoring tools and techniques for Kubernetes clusters, as well as logging best practices.

API Access and Control: Learn about the Kubernetes API and how to interact with it using tools like kubectl. This includes creating and managing resources through the API.

Multi-Node Clusters: If you haven't already, experiment with multi-node clusters and understand how they differ from single-node setups.

Practice, Practice, Practice: Similar to the CKAD, hands-on practice is key. Use platforms like Katacoda or set up your own lab environment to work on real-world scenarios.

Remember, the CKA exam is more focused on cluster administration and system-level tasks. It's a step up from the CKAD in terms of complexity and depth. By concentrating on the areas mentioned above and practicing regularly, you'll be well-prepared to excel in the CKA exam.
