AI-200 Event Driven Integration Practice Question
You are designing an asynchronous AI image classification workflow. Client applications upload images to Azure Blob Storage and need to be notified immediately when processing completes. The notification must include custom metadata generated by the AI worker. Which architecture should you implement?
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
✓
The AI worker publishes a custom event to an Azure Event Grid Topic upon completion.
Publishing custom events to an Event Grid custom topic or system topic allows worker functions to emit structured events with custom payload metadata upon completion.
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 Azure Service Bus topics with session IDs set to the image hash.
Why it's wrong here
While Service Bus can hold messages, Event Grid is the native Azure mechanism for lightweight, reactive event notification.
- ✗
Configure an Azure Storage queue that triggers whenever a blob is modified.
Why it's wrong here
Storage queues do not support pub/sub rich metadata payloads natively like Event Grid.
- ✗
Poll the Azure Blob Storage container metadata every 5 seconds from the client app.
Why it's wrong here
Polling introduces unnecessary latency and API transaction costs, violating event-driven design principles.
- ✓
The AI worker publishes a custom event to an Azure Event Grid Topic upon completion.
Why this is correct
Event Grid custom topics allow applications to push arbitrary event schemas containing custom metadata to subscribers.
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 |
