Preparation

Red Hat encourages all candidates for the Red Hat Certified Specialist in Fast-Cache Application Development exam to consider taking the Red Hat JBoss Data Grid Development (JB453) training course.

Attendance in the course is not required, so one can choose to take just the exam. While attending Red Hat courses can be an important part of one's preparation to take this exam, attending courses 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 using 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

The Red Hat Certified Specialist in Fast-Cache Application Development exam is a performance-based evaluation of a candidate's skills and knowledge of the implementation of applications using JBoss Data Grid. With performance-based testing, candidates must perform tasks similar to what they perform on the job.

In this exam, candidates are asked to perform a number of common development tasks which require the use of certain APIs. Candidates are then evaluated on how well their implementations meet objective criteria such as being able to configure a local cache, set up protocol buffer marshaling, or query local and remote caches.

Even though the exam uses a JBoss Data Grid Platform runtime, candidates do not, and cannot, administer that runtime. The exam has no admin-specific, and only targets well-documented, developer tasks.

Internet access is not provided during the exam, and internet access on your personal devices will be strictly controlled. You are not permitted to bring any printed or electronic documentation into the exam, including notes, books, or any other materials. Documentation that ships with JBoss Data Grid 6.4.1 is available during the exam. Keep these restrictions in mind as you study.

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.

The Red Hat Certified Specialist in Fast-Cache Application Development exam is a hands-on exam that lasts 3 hours.

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.
