AI-200 Event Driven Integration Practice Question
You are implementing an asynchronous AI processing pipeline using Azure Event Hubs. Multiple worker instances consume events from the same Event Hub. To prevent duplicate processing and ensure load balancing across workers, how should you manage consumer checkpoints?
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
✓
Use the Azure Event Hubs EventProcessorClient with an Azure Blob Storage checkpoint store.
Using the Azure Event Hubs `EventProcessorClient` library automatically handles load balancing across partitions and persists checkpoints to an Azure Blob Storage container.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure Azure Service Bus auto-forwarding from Event Hubs to a queue.
Why it's wrong here
Event Hubs does not auto-forward messages to Service Bus natively without an intermediary Azure Function or Stream Analytics job.
- ✓
Use the Azure Event Hubs EventProcessorClient with an Azure Blob Storage checkpoint store.
Why this is correct
The EventProcessorClient coordinates partition ownership across instances and stores checkpoints in Azure Blob Storage.
- ✗
Set the Event Hub partition retention period to zero.
Why it's wrong here
Retention period controls how long data is kept in the stream, not consumer checkpointing or load balancing.
- ✗
Write custom code to maintain consumer offsets in a local memory cache on each worker instance.
Why it's wrong here
In-memory caching is volatile and does not coordinate across multiple distributed worker instances.
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 |
