What you need to know


Red Hat encourages you to consider taking Red Hat OpenShift Application Development I: Containerizing Applications (DO288) 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 one's preparation to take this exam, 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's products are available. Red Hat does not officially endorse any as preparation guides for its exam. Nevertheless, you may find additional reading deepens understanding and can prove helpful.

Exam format

This exam consists of a single section lasting three hours. 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.

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 US 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.
