AI-103 Computer Vision Practice Question
Your application integrates Azure AI Vision and processes images stored in an Azure Blob Storage container. To adhere to security best practices, you want to avoid exposing public blob URLs. How should you provide the image to the Image Analysis API?
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
✓
Download the image bytes in your application code and send them in the binary request body (application/octet-stream).
Instead of public URLs, you can pass the image binary bytes directly in the HTTP request body (using application/octet-stream), or generate a short-lived SAS token URL.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use FTP to transfer images to the vision service endpoint.
Why it's wrong here
FTP is not supported by Azure AI Vision.
- ✓
Download the image bytes in your application code and send them in the binary request body (application/octet-stream).
Why this is correct
Sending binary bytes directly avoids the need for public URLs or SAS tokens.
- ✗
Permanently change the blob container access level to Public Read.
Why it's wrong here
Public blob storage access violates security best practices.
- ✗
Mount the Blob Storage container directly to the Azure AI Vision service via NFS.
Why it's wrong here
Azure AI Vision does not support direct NFS mounting of storage accounts.
Quick reference
Azure Blob Storage Tier Comparison
| Tier | Storage Cost | Retrieval Cost | Latency | Use Case |
|---|---|---|---|---|
| Hot | Highest | Lowest | Immediate | Active data, frequent reads |
| Cool | Lower | Higher | Immediate | Data accessed < once / month |
| Cold | Lower still | Higher | Immediate | Data accessed < once / quarter |
| Archive | Lowest | Highest + rehydration delay | Hours | Long-term compliance retention |
