Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Duplicate detection using a configurable time window
Why this is correct
Duplicate detection prevents identical messages from being enqueued multiple times.
- ✗
Event Hubs partition auto-deletion
Why it's wrong here
Partition auto-deletion does not exist and would cause data loss.
- ✗
Event Grid webhook retry push loops with infinite retention
Why it's wrong here
Event Grid retains undelivered events for at most 24 hours, not infinitely.
- ✗
Storage Queue client-side polling loops
Why it's wrong here
Storage queue polling does not guarantee broker-level Service Bus reliability.
- ✓
Dead-lettering queues for handling poison or unprocessable messages
Why this is correct
Dead-lettering prevents poison messages from blocking queues permanently.
