Opis

This exam is a performance-based evaluation of the skills and knowledge required to effectively use Red Hat JBoss Data Virtualization to model and create a single cohesive, federated view of multiple, complex data sources. Candidates perform a number of routine data modeling and federation tasks and are 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.

The exam consists of one section lasting 4.0 hours.
