Exam PL-200 topic 5 question 23 discussion

Actual exam question from Microsoft's PL-200

Question #: 23
Topic #: 5

A company is training an Al model using a custom table to determine the amount of time it takes to deliver a package based on several key fields.
The testing data used to train the model is used for all training and regression testing scenarios and is considered complete data.
The trained model predicts a 2 percent variance between the estimated delivery time and the actual delivery time of packages.
The executive sponsors reject the model because the actual variance is at 15 percent.
You need to address the sponsors' concern.
What should you do?

A. Replace the training data with real-world data.
B. Reduce the size of the data used within the model.
C. Increase the size of the data used with the model.
D. Use sample training data from Microsoft.

Show Suggested Answer

Suggested Answer: A 🗳️
Note: Start using AI Builder with sample data
Don't have any data of your own to create a model? No problem! We've got you covered.
Sample data is available for several AI Builder model types, together with instructions for working with the sample data.

Not sure what the answer is. I read through this article : https://learn.microsoft.com/en-us/ai-builder/prediction-create-model?source=recommendations It seems like you want to select the most relevant columns (this could be decreasing the size of the data) but you also want to have enough data to train the model (this could be increasing the size of the data).

If I had to make a guess, I'd say it's "Replace the training data with real-world data." because the question states trained model prediction vs. actual variance. If we assume that actual variance is using production data, then we would need to use the same dataset to make an accurate prediction.

shouldn't it be answer D "Use sample training data from Microsoft"?

A) is correct. How exactly will sample data improve the accuracy of the model? Sample data are useful if you do not have any data at all.
