A Guide on Certified Jenkins Engineer Exam


Jenkins is useful for any DevOps role. It is a CI/CD role that helps in better executing the code.

About the Jenkins Certification

CloudBees Inc.®(1), offers two certifications for Jenkins engineers:

  • The Certified Jenkins Engineer (CJE) exam consists of 60 multiple-choice questions testing knowledge of open-source Jenkins.
  • The Certified CloudBees Jenkins Platform Engineer (CCJPE) exam consists of 90 questions: 60 questions testing knowledge of open-source Jenkins and 30 questions testing knowledge of the CloudBees Jenkins Platform.

This exam is comprised of 4 sections:

  1. Key CI/CD/Jenkins concepts
  2. Jenkins usage
  3. Building Continuous Delivery (CD) Pipelines
  4. CD-as-code best practicesAll questions are based on version 1.625.2 of the Jenkins core.

Unless otherwise specified, all questions are based on an out-of-the-box standard installation of Jenkins, without any additional plugins (“base” Jenkins)


This exam will primarily cover questions about a “base” Jenkins installation, but knowledge of the following plugins will also be covered. Candidates are expected to know the functionality/uses of these plugins but will not be tested on detailed usage:

  • Amazon EC2 Plugin
  • Build Pipeline Plugin
  • CloudBees Docker Build and Publish Plugin
  • CloudBees Folders Plugin
  • Copy Artifact Plugin
  • Credentials Plugin
  • Disk Usage Plugin
  • Docker Plugin
