Preparation
Red Hat encourages all candidates  for the Red Hat Certificate of Expertise in Ansible Automation exam to consider taking the Cloud Automation with Ansible course (DO407). Attendance in this class is not required to take the exam.

While attending Red Hat classes can be an important part of one's preparation to take this exam, 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's products are available. Red Hat does not officially endorse any as preparation guides for its exams. Nevertheless, you may find additional reading deepens understanding and can prove helpful.

Exam Format
This exam is a performance-based evaluation of a candidate’s ability to use Ansible to automate system configuration and application deployment.  Candidates will be required to develop Ansible playbooks that configure systems for specific roles and then apply those playbooks to systems to implement those roles.  Candidates will also be asked to demonstrate their ability to run Ansible playbooks and configure an Ansible environment for specific behaviors. Candidates will be evaluated on whether they have met specific objective criteria.

Performance-based testing means that candidates must perform tasks similar to what they perform on the job.
 
This exam consists of one section lasting 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 total scores. Red Hat does not report performance on individual items, nor will it provide additional information upon request.
