Exam description

The Red Hat Certified Advanced Developer in Cloud-native Applications exam (EX288) tests your ability to deploy existing applications in a Red Hat® OpenShift® Container Platform environment.

This exam is based on Red Hat OpenShift Container Platform 4.22.

Earning a passing score on this exam is a requirement to attain the Red Hat Certified Advanced Developer in Cloud-native Applications  certification.

Exam Delivery

This is a hands-on, practical exam.  Rather than answering multiple-choice questions, you are required to perform routine system tasks on a live system to meet specific objective criteria.

The tasks are based on Red Hat OpenShift Container Platform 4.22..  Relevant product documentation is provided during the test, but you must complete the tasks without outside assistance.

Exam results are reported via email 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.
