CKAD Examination Review
Requirements
To maximize the effectiveness of this training, participants should possess:
Proficiency in basic Linux command-line operations and file editing, along with familiarity with programming languages such as Python, Node.js, or Go. Knowledge of Cloud Native application concepts and architectures, such as those presented in the free Introduction to Kubernetes edX MOOC, is beneficial for this course.
Note that Kubernetes Administration (LFS458) is not a prerequisite for this module. There is significant overlap in the content, as each course is designed to be self-contained and aligned with its respective examination standards.
Audience
This course is intended for experienced application developers who require the ability to containerize, host, deploy, and configure applications in a multi-node cluster.
Experience Level: Intermediate
