Red Hat Certified JBoss Administration (RHCJA) exam

You are viewing information for:

The Red Hat® Certified JBoss® Administration (RHCJA) exam (EX248) is a performance-based exam that tests your knowledge and skills to install, configure, monitor, manage, and deploy applications to Red Hat JBoss Enterprise Application Platform (EAP).

RHCJA certification is for system administrators or application developers whose responsibilities include the deployment, implementation, and management of Red Hat JBoss EAP and its applications.

The exam based on Red Hat EAP 6 is available via on-site and Individual exam sessions. Details

In preparation

Red Hat recommends that candidates earn Red Hat Certified System Administrator (RHCSA) or Red Hat Certified Engineer (RHCE) before attempting this exam, but neither is required. An understanding of core concepts in Java Enterprise Edition is useful, but candidates do not need to be developers nor does this exam involve application development tasks.

To help you prepare, the exam objectives highlight the task areas you can expect to see covered in the exam. These objectives apply to both Red Hat EAP 6 and EAP 6.3.

Red Hat reserves the right to add, modify, and remove exam objectives. Such changes will be made public in advance.

What you need to know

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.

Exam format

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 EAP.

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.

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 EAP 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.

RHCJA 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/UNIX experience 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.

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 section scores. Red Hat does not report performance on individual items, nor will it provide additional information upon request.
