The Red Hat Certified Specialist in Camel Development exam (EX421) tests your abilities to create and maintain enterprise integration services using Camel with Red Hat® Fuse.

By passing this exam, you become a Red Hat Certified Specialist in Camel Development, which also counts toward becoming a Red Hat Certified Architect (RHCA®).

• Enterprise Java developers who are familiar with service-oriented architecture (SOA) principles and are responsible for integrating enterprise applications
• Enterprise SOA architects with some Java development experience and knowledge of enterprise integration

To help you study, the exam objectives below highlight the task areas you can expect to see covered in the exam.

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

• Wire Tap
• Splitter
• Aggregator
• Recipient list

Use Camel components

• File2
• FTP
• JPA2
• JMS
• Direct
• Rest

Use Camel Test

As with all Red Hat performance-based exams, configurations must persist after reboot without intervention.

Red Hat encourages you to consider taking Camel Integration and Development with Red Hat Fuse (AD421) 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. Red Hat does not endorse any of these materials as preparation guides for exams. Nevertheless, you may find additional reading helpful to deepen your understanding.

This exam is a performance-based evaluation of your Camel development skills and knowledge. You will perform tasks associated with the development and maintenance of enterprise integration patterns using Red Hat Fuse. Performance-based testing means that you must perform tasks similar to those you perform on the job.

Internet access is not provided during this closed exam, and you will not be permitted to bring any hard copy or electronic documentation into the exam. This prohibition includes notes, books, or any other material. However, you are provided with a local copy of the official Fuse documentation. You should familiarize yourself with this documentation when preparing for the exam.

This course is intended to develop the skills needed to produce more resilient, mission-critical integration solutions with Red Hat Fuse and Camel, resulting in less development time spent maintaining and developing integration solutions.

As a result of taking this course, you will have a strong understanding of fundamental Camel concepts, commonly used Camel components and their configurations, and Camel deployment options. You will also develop a thorough grasp of enterprise integration patterns to solve integration problems.

You will be able to demonstrate these skills:

• Develop Camel routes to integrate systems such as JMS, FTP, Databases, and REST services.
• Filter and transform messages to create integration routes that are highly reliable.
• Develop tests and use mock components to thoroughly test routes.
• Create reliable routes by implementing transactional routes that prevent data loss.
• Increase message throughput by implementing parallel processing in routes.
• Deploy routes with Red Hat OpenShift Container Platform.
