How to study for 1Z0-1084-23 - Oracle Cloud Infrastructure 2023 Certified Developer Professional

Hi everyone,

I decided to take all the 2023 OCI exams to check what changed and guide people in taking these certifications.

Well, not all exams. I will do only the ones that I did in 2019 to 2022 and are the things that I work on a day-to-day basis 🙂

On this test, I was expecting to see a lot of new things(comparing the course topics with the previous years and OCI database improvements) and that was true, a lot of new questions. 

A good starting point is here:


I hope Oracle is planning to allow us to download the PDFs again because the online reader is terrible. From 0 to 10, the usability of this tool is -1, especially on mobile devices.

What do you need to focus on?

  • Cloud-Native Architecture
  • Kubernetes
  • Docker
  • Microservices
  • Software Testing
  • OCI Logging Services
New Topics:
  • OCI Service Mesh
  • Serverless Queues

Some of the content of this test is not in the videos or PDFs, this is why it's always good to read the OCI Official documentation.

Don't forget to read the topics:


The practice exam is good and you can have a good feel of what to expect during the exam.

But I recommend you to have a free account and test everything you can!

Additional material:

And last but not least, stay away from Brain Dumps!

Best of luck
Alex Zaballa
