You are building an internet-based training solution. The solution requires that a user's camera and microphone remain enabled.
You need to monitor a video stream of the user and verify that the user is alone and is not collaborating with another user. The solution must minimize development effort.
What should you include in the solution?
The correct solution for monitoring a video stream to verify that a user is alone and not collaborating with another user is to use Spatial Analysis in Azure AI Vision. Spatial Analysis is specifically designed to analyze spatial relationships and detect the presence and movements of people within a video feed. This capability makes it effective for ensuring that a user is isolated and not interacting with others, fulfilling the requirement to monitor the user and minimize development effort.
"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
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

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."
but why B and D are equal?
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
