  • 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.

The exam is a performance-based evaluation of your ability to deploy applications in a Red Hat OpenShift Container Platform environment. You will perform a number of routine tasks similar to those you would be expected to perform in an OpenShift Container Platform DevOps environment and will be evaluated on whether you have met specific objective criteria.
