Exam AI-102 topic 3 question 76 discussion

Spatial Analysis in Azure AI Vision allows you to analyze video streams and detect the presence of people and their movements within a defined space. This service can help you determine if a user is alone or if others are present, which is crucial for ensuring compliance in a training environment where collaboration is not allowed. C for correct

However, On 30 March 2025, Azure AI Vision Spatial Analysis will be retired. https://learn.microsoft.com/en-us/azure/ai-services/computer-vision/spatial-analysis-operations

A speech solution makes no sense because you can collaborate and cheat visually without sound. Object detection requires a lot of effort and does not entirely meet the goal.

must be A. look at Question " user's camera and microphone remain enabled" . According to Q, I expect that these are laptop's camera and microphone. so, this camera can not watch entire roop view. Detect Voice then STT must be right answear.

This must be speech to text.

Spatial is right answer , option b and d is the same option , if this is a real MS exam it could get better a lot.

The zone must be fully covered by a single camera in order for PersonCount to record an accurate total."

ChatGPT, Gemini and Claude is also voting for C.

and what if the another person is out of the camera and is talking ?

"How does Azure AI Vision analyze people in a physical space? The spatial analysis AI models detect and track movements in the video feed based on algorithms that identify the presence of one or more humans by a body bounding box." Answer: C. Spatial Analysis

"How does Azure AI Vision analyze people in a physical space? The spatial analysis AI models detect and track movements in the video feed based on algorithms that identify the presence of one or more humans by a body bounding box."

but why B and D are equal?

To monitor a video stream of the user and verify that the user is alone and not collaborating with another user, you should include Spatial Analysis in Azure AI Vision in your solution. This service can analyze the spatial relationships between people, movements, and interactions in a physical space using video data. So, the correct answer is: C. Spatial Analysis in Azure AI Vision

For the specific scenario of monitoring a video stream to verify that a user is alone and not collaborating with another user, object detection using Azure AI Custom Vision is a more suitable choice. Object detection can identify and track objects or people within the video stream, allowing you to determine if multiple individuals are present. It aligns better with your goal and minimizes development effort. The selected answer should be B
