AI-102 Implement computer vision solutions Practice Question
You are building a mobile app that uses Azure AI Vision to generate captions for photos taken by users. The app must work offline in areas with no internet connectivity. Which Azure AI Vision feature should you use?
⚠ Common exam trap
The trap here is overlooking that Docker containers can run AI services locally, while the cloud APIs require connectivity.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure AI Vision Docker container for Image Analysis
The Azure AI Vision Docker container for Image Analysis allows you to run the captioning feature locally, enabling offline operation. This is the only option that provides the required functionality without internet connectivity, making it the correct choice for a mobile app that must work in areas with no network.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure AI Vision Docker container for Image Analysis
Why this is correct
Azure AI Vision provides Docker containers that can run the Image Analysis capabilities locally, including caption generation. These containers can be deployed on-premises or on edge devices, enabling offline operation. By using the container, the mobile app can communicate with a local endpoint without internet, satisfying the offline requirement.
- ✗
Azure AI Custom Vision
Why it's wrong here
Custom Vision is used to build custom image classification or object detection models, not to generate generic captions. It also typically requires cloud connectivity for training and prediction, unless exported as a model for offline use, but it does not provide captioning. Thus, it does not meet the offline captioning need.
- ✗
Azure AI Vision Read API
Why it's wrong here
The Read API extracts text from images but does not generate descriptive captions. It is also a cloud service that requires connectivity. Since the requirement is to generate captions offline, the Read API does not provide the needed functionality and would not work without internet.
- ✗
Azure AI Vision Image Analysis API
Why it's wrong here
The Image Analysis API is a cloud-based service that requires internet connectivity to send images and receive captions. It cannot run offline on a mobile device. If the app must work offline, relying on this API would cause failures when there is no network, making it unsuitable for the scenario.
