[All Databricks Certified Professional Data Scientist Questions]

You are working as a data science consultant for a gaming company. You have three member team and all other stake holders are from the company itself like project managers and project sponsored, data team etc. During the discussion project managed asked you that when can you tell me that the model you are using is robust enough, after which step you can consider answer for this question?

AData Preparation

BDiscovery

COperationalize

DModel planning

EModel building
To answer whether the model you are building is robust enough or not you need to
have answer below questions at least
- Model is performing as expected with the test data or not?
- Whatever hypothesis defined in the initial phase is being tested or not?
- Do we need more data?
- Domain experts are convinced or not with the model?
And all these can be answered when you have built the model and tested with the test data sets. Hence, correct option will be Model Building.

Yeah, but if the data is bad, the model won't be robust no matter what!

Wait, can we really trust the model just after building?

I disagree, operationalize is where you see real-world performance.

I think data preparation is key too, though.

Definitely model building! You need to test it first.

Yeah, I practiced a question like this before, and it seemed clear that model building is where we validate everything. So, I’m leaning towards that option.

I feel like the discovery phase might be crucial too, but I guess we can't really confirm robustness without building the model first.

I'm not so sure though. Could it be that we need to consider the operationalize step as well? I remember something about deploying the model being important.

I think the answer is definitely related to model building since that's when we actually test the model's performance, right?

Hmm, I'm not entirely sure about this one. The datalayer could be used for a few different purposes, so I'll need to think it through carefully before selecting an answer.

I'm pretty confident this is option B. The question mentions the trial version, so I think the serial number update would be done in the Software Evaluation Status window.

I remember practicing a question just like this and I believe the reporting helps identify malicious activity more effectively.
