EX294 Exam Description - (RHCE) exam for Red Hat Enterprise Linux 8

The performance-based Red Hat Certified Engineer (RHCE) exam for Red Hat Enterprise Linux 8 (EX294) tests your knowledge and skill in managing multiple systems using Red Hat Ansible Engine and executing common system administration tasks across a number of systems with Ansible. The skills tested in this exam are the foundation for system administration across many Red Hat products.

By passing this exam, you become a Red Hat Certified Engineer. An RHCE is a Red Hat Certified System Administrator (RHCSA) who is ready to use Ansible and scripting to automate Red Hat Enterprise Linux tasks, integrate Red Hat emerging technologies, and apply automation for efficiency and innovation. If you choose to continue your learning journey beyond RHCE, the credential can also serve as a foundational step on your path toward our highest level of certification—Red Hat Certified Architect.

This exam is based on Red Hat Enterprise Linux 8 and Red Hat Ansible Engine 2.8. An RHCE will still be earned by having first passed the Red Hat Certified System Administrator exam (EX200) and then passing an RHCE exam while still current as an RHCSA.
