Red Hat is not responsible for the content or accuracy of other guides, books, online resources, or any other information provided by organizations or individuals other than Red Hat Training and Certification. Red Hat reserves the right to change this guide when appropriate. Candidates who have enrolled in forthcoming classes or exams are advised to check this guide periodically for changes.

Prospective employers of a candidate holding RHCJA certification should verify any and all claims by people claiming to hold this credential by requesting the certificate number and verifying it using the Red Hat certification verification tool.

Performance-based exams

The RHCJA exam is a performance-based evaluation of a candidate's skills and knowledge regarding the administration of enterprise applications based on and using JBoss Enterprise Application Platform.

Candidates perform a number of routine system administration tasks and are evaluated on whether they have met specific objective criteria. Performance-based testing means that candidates must perform tasks similar to what they must perform on the job.

Format of the RHCJA exam

The RHCJA exam is a hands-on, practical exam that lasts 4 hours. Internet access is not provided during the exam. You will not be permitted to bring any hard copy or electronic documentation into the exam. This prohibition includes notes, books, or any other materials. Internet access will be strictly controlled. Documentation that ships with JBoss Enterprise Application Platform is available during the exam.

Red Hat reserves the right to make changes to the exam format, including timing and the policies above. Such changes will be made public in advance through revisions to this document.

Preparation for the RHCJA exam

Experience is the best preparation for the exam. However, even experienced people sometimes have gaps in their knowledge, so Red Hat encourages all candidates for RHCJA to consider taking the JB248 JBoss for Administrators I course. This course introduces the topic and can be an effective supplement to experience and a valuable aid in preparation for the exam. Attendance in this class is not required, and one can choose to take just an exam.

While attending Red Hat's classes can be an important part of your preparation, it does not guarantee success on the exam. Previous experience, practice, and native aptitude are also important determinants of success.

JBCAA exam environment

You will be working on a Red Hat Enterprise Linux® 6 system during the exam, so prior experience using Linux or UNIX will be helpful. The purpose of this exam is not to test operating system administration skills, and extensive Linux/UNIXexperience is not required. You will have a full desktop environment in which to work, and we will provide a list of basic commands for your reference in addition to the man pages and other documentation that come with Red Hat Enterprise Linux.

Fedora provides a freely available alternative for you to practice your Linux skills. A Live CD version is available that allows you to work on Fedora without needing to install it on your computer. While it is not an exact match for the environment in Red Hat Enterprise Linux, it is definitely close enough for the level of familiarity required.
