Detailed Review Of Preparation

I recently cleared the OCI foundations 2020 exam. Although the other review on this exam on this very website are sufficient, the following could be useful to someone studying for this exam : 

1. Make sure to go through the video lectures twice in order to understand everything better.
2. Although the online videos on Oracle University are enough, try and read more about each service from the official website.
3. Databases and Storage make up a good portion of the exam.
4. Read about all the ways to connect your on-premise resources to OCI.
5. Shared security model is important.
6. Make sure to read about SLAs and Audit services since these weren't covered in the online lectures.
