Preparation

Red Hat encourages you to consider taking Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) to help prepare. 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

The PE180 exam is a hands-on, practical exam that requires candidates to undertake real world tasks. Internet access is not provided during the exam. You will not be permitted to use any hard copy or electronic documentation during the exam. This prohibition includes notes, books, or any other materials. Internet access will be strictly controlled. Documentation that ships with podman is available during the exam.

Scores and reporting                  

Official scores for exams come exclusively from Red Hat Certification Central. Red Hat does not authorize examiners or training partners to report results to candidates directly. Scores on the exam are usually reported within 3 U.S. business days.

Exam results are reported as total scores. Red Hat does not report performance on individual items, nor will it provide additional information upon request.
