Are the current exams for 11g certification based strictly on 11gR1 or 11gR2?
While studying and having questions, I don't know if I should look into 11gR2 or 11gR2 official documentation to find answers.
Maybe there's differences between these two releases that can guide me wrong on possible exam questions.
The exams were created against 11gR1, but have been validated against 11gR2. OU does not *want* questions in the exams that have a different answer between releases. The 11gR2 validation would have ensured that none exist. I would recommend studying the R2 documentation as it is always best to make use of the most current incarnation of any given major release.
