AI-200 Event Driven Integration Practice Question
You are building an order processing system with Azure Service Bus. Multiple clients might accidentally submit the exact same order twice within a 60-second window due to network retries. You need to prevent duplicate orders from entering the queue. What should you configure?
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
✓
Enable Duplicate Detection on the queue and set the history time window to 60 seconds.
Azure Service Bus provides Duplicate Detection. When enabled, the broker inspects the MessageId property of incoming messages within a configurable time window (DuplicateDetectionHistoryTimeWindow) and drops duplicates.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable Duplicate Detection on the queue and set the history time window to 60 seconds.
Why this is correct
Duplicate detection uses the MessageID to automatically discard messages with identical IDs sent within the specified time window.
- ✗
Configure Auto-Forwarding to a dead-letter queue with a 60-second TTL.
Why it's wrong here
Auto-forwarding moves messages between entities; it does not check for duplicate message IDs.
- ✗
Set the LockDuration property to 60 seconds.
Why it's wrong here
LockDuration governs processing locks, not duplicate suppression.
- ✗
Enable partitioning and set the partition key to the client IP address.
Why it's wrong here
Partitioning is for scaling throughput, not deduplication.
