Microsoft DP-100 Exam - Topic 7 Question 56 Discussion

Actual exam question for Microsoft's DP-100 exam

Question #: 56
Topic #: 7

You use the designer to create a training pipeline for a classification model. The pipeline uses a dataset that includes the features and labels required for model training.

You create a real-time inference pipeline from the training pipeline. You observe that the schema for the generated web service input is based on the dataset and includes the label column that the model predicts. Client applications that use the service must not be required to submit this value.

You need to modify the inference pipeline to meet the requirement.

What should you do?

AAdd a Select Columns in Dataset module to the inference pipeline after the dataset and use it to select all columns other than the label.

BDelete the dataset from the training pipeline and recreate the real-time inference pipeline.

CDelete the Web Service Input module from the inference pipeline.

DReplace the dataset in the inference pipeline with an Enter Data Manually module that includes data for the feature columns but not the label column.

Show Suggested Answer

Suggested Answer: A

By default, the Web Service Input will expect the same data schema as the module output data which connects to the same downstream port as it. You can remove the target variable column in the inference pipeline using Select Columns in Dataset module. Make sure that the output of Select Columns in Dataset removing target variable column is connected to the same port as the output of the Web Service Intput module.

Option D could work too, but it feels a bit manual.

Wait, why would you delete the dataset? That sounds risky!

Option A is the way to go! Just select the columns you need.

I feel like replacing the dataset with an Enter Data Manually module could work, but it seems like a lot of extra steps.

I’m a bit confused about whether deleting the dataset entirely would work. Wouldn't that just complicate things?

I remember a similar question where we had to adjust the input schema, and I think option A makes the most sense here.

I think we need to remove the label column from the input, but I'm not sure if adding a Select Columns module is the right approach.

Hmm, this looks like a tricky one. I'll need to think through the different options carefully.

Easy peasy! The answer is clearly B - you want to add features to show your professionalism, not make the app overly simple.

Ugh, options questions are the worst. I'm just going to guess and hope for the best. Let's see, the difference between the strike prices is $10, so maybe the answer is $500? Or is it unlimited profit since Bubba has a spread position? I'm not sure, but I'll give it my best shot.

Hmm, this seems like a tricky one. I'll need to think carefully about the implications of message-layer security and how that might impact the ability to forward messages.
