Exam Details: What to Expect
The CKS exam is a hands-on, proctored exam. You'll be given a set of tasks to perform on a live Kubernetes cluster. You’ll have two hours to complete all the tasks. Knowing what to expect on the CKS exam is crucial for effective preparation and success. The exam is a hands-on, proctored exam, meaning that you will be monitored remotely while you complete the tasks. This format ensures that the exam is fair and that candidates cannot cheat or receive unauthorized assistance. The exam consists of a series of practical tasks that you must complete on a live Kubernetes cluster. These tasks are designed to assess your ability to apply security principles and best practices in a real-world environment. The tasks cover a wide range of security topics, including cluster hardening, system hardening, minimizing microservice vulnerabilities, network security, and monitoring, logging, and runtime security. To pass the exam, you need to demonstrate a deep understanding of these topics and be able to apply them effectively. The exam environment is typically a command-line interface (CLI), so you should be comfortable working with Kubernetes using tools like kubectl. You will be given access to documentation and other resources during the exam, but you will not be able to access external websites or consult with others. Therefore, it is essential to be familiar with the Kubernetes documentation and to practice using the various security tools and techniques before the exam. The exam is timed, so you need to manage your time effectively. It is important to prioritize tasks, focus on the most critical issues first, and avoid getting bogged down in minor details.
