How to study for 1Z0-1089-21 - Oracle Cloud Infrastructure 2021 HPC and Big Data Solutions Associate

 Hi all,

I decided to take all the 2021 OCI exams to check what changed and guide people in the process of taking these certifications.

Well, not all the exams. I will do only the ones that I did in 2019/2020 and are the things that I work on a day-to-day basis 🙂

On this test, I was not expecting to see new things (comparing the exam topics with the previous one). 

I got between 3 to 5 new questions.

Of course, I don't remember the question from the 2020 exam (did it one year ago), but I didn't remember studying these topics on the new questions before.

You can find the material here:

Official Documentation:

User guide:

You can find some examples of questions here:

If you did this exam last year, try to focus on Oracle Data Science and learn these new concepts.

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

Best of luck

How to study for 1z0-1094-21 - Oracle Cloud Database Migration and Integration 2021 Specialist

Hi all,

This is a new exam and it's great to test your knowledge.

I have the impression that this exam was different from the previous tests.

This exam privileges the knowledge acquired on a daily basis much more than the knowledge acquired in preparation for the test.

On this preparation material, I missed having something about how to analyze the workload of environments before migration and how this impacts the decision of choosing the shape and type of service to be used in the Cloud.
It's also missing some checks you have to do before work in a big production migration.
And I think they should share more about Cloud Premigration Advisor Tool.

Since I created mig360 and I'm working on Cloud migration projects, the "regular" database migration topics on this test are ok.

For ZDM topics, I think I should have tested more. 
The material for this exam is not sufficient. 
For sure you will need some real-world experience to clear most of the questions ZDM related.

About the ODI topics, It was very deep (much more than I expect).
Even working on environments that I have to deal with ODI every day, A lot of questions are difficult to answer if you are not an ODI Developer.

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

Best of luck
