AI-200 Event Driven Integration Practice Question
Your application uses Azure Service Bus Queues. A spike in traffic causes multiple worker instances to contend for messages. You want to ensure that when a worker locks a message, no other worker can process it, and the lock is automatically renewed in the background if processing takes longer than expected. Which client library feature should you use?
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 Auto-Lock Renewal on the message processor client.
Modern Azure Service Bus SDKs include an auto-lock renewal feature (e.g., `MaxAutoLockRenewalDuration` in .NET) that automatically extends the message lock while the handler is executing.
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 Auto-Lock Renewal on the message processor client.
Why this is correct
Auto-lock renewal background tasks keep extending the lock duration automatically until message processing completes.
- ✗
Increase the LockDuration property on the queue to 2 hours permanently.
Why it's wrong here
Setting a permanent 2-hour lock duration is bad practice because if a worker crashes, the message remains locked for 2 hours before another worker can retry it.
- ✗
Use Event Grid advanced filters to throttle incoming messages.
Why it's wrong here
Event Grid filters do not manage Service Bus message locks.
- ✗
Switch the queue to ReceiveAndDelete mode.
Why it's wrong here
ReceiveAndDelete deletes the message immediately, risking data loss if the worker crashes.
