Actual exam question for Microsoft's AI-102 exam

Question #: 24
Topic #: 1

Your company uses an Azure Cognitive Services solution to detect faces in uploaded images. The method to detect the faces uses the following code.

You discover that the solution frequently fails to detect faces in blurred images and in images that contain sideways faces.

AUse a different version of the Face API.

BUse the Computer Vision service instead of the Face service.

CUse the Identify method instead of the Detect method.

DChange the detection model.
You need to increase the likelihood that the solution can detect faces in blurred images and images that contain sideways faces.
What should you do?

Show Suggested Answer

Suggested Answer: D

Evaluate different models.

The best way to compare the performances of the detection models is to use them on a sample dataset. We recommend calling the Face - Detect API on a variety of images, especially images of many faces or of faces that are difficult to see, using each detection model. Pay attention to the number of faces that each model returns.

Not sure if just changing the model will fix the blur problem.

Wait, does the Face API really not work well with sideways faces?

Changing the detection model sounds like the best option here.

I think switching to the Computer Vision service could help!

The Face API struggles with blurred images, that's a known issue.

I’m a bit confused about the Identify method versus the Detect method; I thought they served different purposes, but I can’t recall the details.

I think using the Computer Vision service might be a good option, but I’m not entirely clear on how it compares to the Face service for this specific issue.

I remember reading about the different versions of the Face API, but I'm not sure if switching versions would help with blurred images.

I practiced a similar question where changing the detection model improved accuracy, so I’m leaning towards option D.

I've got it! The number shows the number of unique values for the field, not the total number of values. Option C is the right answer.

This question seems pretty straightforward. I think forming an alliance with a local supplier would be the best option to help grow Mitch's business.

I'm leaning towards option A, but I'm not entirely confident... The idea of a utility service sounds right, though.

Hmm, this looks like a tricky STP question. I'll need to carefully review the options and think through the Cisco ACI configuration steps.
