AI-200 Event Driven Integration Practice Question
Your team is building an AI solution that processes thousands of images uploaded to Azure Blob Storage daily. Each image upload must trigger an immediate Azure Function to invoke Azure Cognitive Services for metadata extraction. Which event-driven messaging service should you choose for this near real-time pub/sub architecture?
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 Event Grid
Azure Event Grid is designed for reactive programming and near real-time event routing, making it ideal for triggering serverless functions when blob storage events occur.
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 Service Bus Topics
Why it's wrong here
Service Bus is designed for enterprise messaging requiring complex transactions, ordering, and session management, not simple blob event routing.
- ✗
Azure Storage Queues
Why it's wrong here
Storage Queues provide simple queueing but lack the robust pub/sub event filtering and routing capabilities of Event Grid.
- ✗
Azure Event Hubs
Why it's wrong here
Event Hubs is optimized for big data streaming pipelines and telemetry ingestion, not discrete event notifications from storage.
- ✓
Azure Event Grid
Why this is correct
Event Grid is built for reactive event notification with low latency and high scale, perfectly suited for blob storage triggers.
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 |
