AI-200 Event Driven Integration Practice Question
Your application sends messages to an Azure Service Bus queue. A downstream worker needs to postpone processing of a specific message until a later time without losing its place in the queue or dead-lettering it. What method should the worker invoke?
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
✓
DeferMessageAsync()
Service Bus supports message deferral. A receiver can call `DefferMessageAsync()` on a received message, which moves it into a deferred state where it can only be retrieved by its unique `SequenceNumber` later.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
CompleteMessageAsync()
Why it's wrong here
Complete deletes the message from the queue, signaling successful processing.
- ✓
DeferMessageAsync()
Why this is correct
Deferral sets the message aside in a deferred state, preserving its sequence number for later retrieval.
- ✗
AbandonMessageAsync()
Why it's wrong here
Abandon releases the lock immediately and returns the message to the active queue for instant redelivery.
- ✗
DeadLetterMessageAsync()
Why it's wrong here
Dead-lettering moves the message to the DLQ for error inspection, not delayed normal processing.
