About the OGEA-101 Exam

The OGEA-101 exam, officially titled The Open Group TOGAF Enterprise Architecture Part 1, is the foundational certification for professionals seeking to master the TOGAF framework. Offered by The Open Group, this exam validates your understanding of the core concepts, terminology, and principles of enterprise architecture as defined by the TOGAF standard.
