Course Details

Preparation

Red Hat encourages you to consider taking Red Hat Application Development II: Implementing Microservice Architectures (JB283) 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.
