This exam was my first Oracle Exam in Brazilian Portuguese, as a native Portuguese speaker, is nice to see this type of initiative from big companies.
About the exam, I’m used to work in OCI Console using English language, so in some questions I spent time trying to translate terms from Portuguese to English.
As usual, hands-on experience in console/API will help a lot to be successful in this

To study I have used the official documentation (I really like to read everything in docs) and the videos from Mylearn helped a lot.
Be prepared to answer questions from Network and IAM (remember, this is an Introduction level exam) and you will be fine.
