- Azure AI Video Indexer
- Azure AI Vision Spatial Analysis (Correct answer)
- Azure Media Services
- Azure Digital Twins
Correct answer: Azure AI Vision Spatial Analysis
Azure AI Vision Spatial Analysis processes live video to detect people, track movement, and understand spatial interactions in physical spaces.
Question 2: Which feature of Azure AI Vision can detect whether a submitted image contains adult or violent content?
- Face detection
- Image analysis – content moderation (Correct answer)
- Optical character recognition
- Smart cropping
Correct answer: Image analysis – content moderation
Azure AI Vision's image analysis includes a content moderation feature that scores images for adult and violent content on a confidence scale.
Question 3: What type of output does Azure Custom Vision's object detection model return?
- A single class label for the image

- A sentiment score for the scene
- A textual description of the image
Correct answer: Bounding box coordinates and class labels for each detected object
Custom Vision object detection returns bounding box coordinates (left, top, width, height) along with class labels and confidence scores for each detected object.
Question 4: In Azure AI Vision, what does 'smart cropping' do?
- Removes background noise from images
- Automatically crops an image to focus on the most interesting region (Correct answer)
- Enhances image resolution using AI
- Detects text regions for OCR processing
Correct answer: Automatically crops an image to focus on the most interesting region
Smart cropping uses saliency detection to automatically generate thumbnail crops that focus on the most visually interesting area of an image.
Question 5: Which Azure AI service can analyze videos to extract insights like speakers, topics, and transcript?
- Azure AI Vision
- Azure AI Video Indexer (Correct answer)
- Azure AI Speech
- Azure AI Document Intelligence
Correct answer: Azure AI Video Indexer
Azure AI Video Indexer automatically extracts insights from videos including transcripts, speaker identification, sentiment, topics, and key frames.
Question 6: What is a 'tag' in the context of Azure AI Vision image analysis?
- A metadata label attached to an Azure resource
- A keyword describing objects, actions, or concepts visible in an image (Correct answer)
- A bounding box coordinate for object detection
- An error code returned when image analysis fails
Correct answer: A keyword describing objects, actions, or concepts visible in an image
Azure AI Vision returns tags — descriptive keywords with confidence scores that identify recognizable objects, scenes, and actions present in an image.
