Preparation for the RHCSA in Red Hat OpenStack


We encourage you to consider attending  CL110 Red Hat OpenStack Administration I: Core Operations for Cloud Operators  and CL210 Red Hat OpenStack Administration II: Infrastructure Configuration for Cloud Administrators 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. We do 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 Red Hat OpenStack skills and knowledge. You will be asked to perform a number of systems administration tasks focused on configuring and administering an OpenStack cloud and will be evaluated on whether you have met specific objective criteria. Performance-based testing means that you must perform tasks similar to what you will perform on the job. This exam consists of one section lasting 4 hours.
