Application development in the age of Agile and DevOps means that today’s workflows need to embrace Continuous Integration (CI) and Continuous Delivery (CD) to ensure that your team is keeping pace with ever-changing customer requirements and maintain your competitive edge in an increasingly dynamic marketplace. To do this, you need to design and implement the pipelines to support the speed and flexibility of modern application development. With its suite of powerful plug-ins, Jenkins has been an industry leader in pipeline automation and management for many years, and experienced Jenkins engineers are in ever higher demand. The best way to show your proficiency is by attaining the Certified Jenkins Engineer (CJE) status.

In this learning path, intended for those with intermediate-level experience or administrator-level proficiency with the open source version of Jenkins, your host, trainer and CJE, Benjamin Muschko, walks you through the topics covered in the exam so that you can fully prepare to pass and earn your CJE. You begin with an overview of the exam environment itself and the high-level goals of the exam. You then move on to a review of general CI/CD terminology and how it applies to Jenkins concepts. You’ll look at how to create CI/CD models that are scalable, maintainable, and secure. This learning path offers many demonstrations to help reinforce what you're learning. When you’ve completed it, you should be in a good position to pass the exam and add the initials “CJE” to your title and resume.
