CKAD exam review
Requirements
To maximize the benefits of this course, you should possess:
Basic proficiency in Linux command-line operations and file editing, along with familiarity with using a programming language (such as Python, Node.js, or Go). Understanding of Cloud Native application concepts and architectures (similar to those taught in our free Introduction to Kubernetes edX MOOC) is beneficial for this course.
Please note that Kubernetes Administration (LFS458) is not a prerequisite for this course. While there is overlap in the materials, each course is designed to stand alone and aligns with its respective exams.
Audience
This course is intended for experienced application developers who need to containerize, host, deploy, and configure applications within a multi-node cluster.
Experience Level: Intermediate
