The Red Hat Certified Specialist in OpenShift Virtualization exam (EX316) tests the knowledge, skills, and ability to plan, deploy and manage virtual machines using the Red Hat OpenShift Virtualization operator in a Red Hat OpenShift Container Platform environment.
Objectives listed for this exam are based on the most recent Red Hat product version available.
Red Hat Certified Specialist in OpenShift Virtualization Exam (EX316K) - Individual Exam
By passing this exam, you become a Red Hat Certified Specialist in OpenShift Virtualization that also counts towards earning a Red Hat Certified Architect (RHCA®).
- Site reliability engineers (SREs), cluster engineers, systems administrators, cloud administrators, or cloud engineers focused on planning, designing, and implementing production-grade virtual machines under OpenShift clusters and at the same time ensuring these virtual machines remain in compliance with corporate standards
Duration: 4 hours
Red Hat encourages you to consider taking Managing Virtual Machines with Red Hat OpenShift Virtualization (DO316) to help prepare for this exam. 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 consists of a single section lasting four hours. The exam is a performance based evaluation of candidates' abilities to implement Red Hat OpenShift Virtualization operator and virtual machines in an OpenShift Container Platform cluster. Candidates perform a number of routine tasks similar to those they would be expected to perform in a large-scale environment and are evaluated on whether those tasks meet specific objective criteria. Internet access is not provided during the 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 materials. For most exams, the documentation that ships with the product is available during the exam.
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.
