Preparation

Red Hat encourages you to consider taking Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) and Red Hat OpenShift Administration I (DO280) to help prepare for this exam. Attendance in these classes is not required; students can choose to take just the exam.

While attending Red Hat classes can be an important part of your preparation, attending class does not guarantee success on the exam. Previous experience, practice, and native aptitude are also important determinants of success.

Many books and other resources on system administration for Red Hat products are available. Red Hat does not endorse any of these materials as preparation guides for exams. Nevertheless, you may find additional reading helpful to deepen your understanding.

Exam format

This exam is a performance-based evaluation of skills and knowledge required to configure and manage Red Hat OpenShift Container Platform. You will perform the configuration and administrative tasks necessary to deploy Red Hat OpenShift Container Platform and are evaluated on whether you have met specific objective criteria. Performance-based testing means that you must perform tasks similar to what you perform on the job.
