AI-200 Event Driven Integration Practice Question
You are designing an asynchronous AI transaction pipeline using Azure Service Bus. You need to implement the Competing Consumers pattern where multiple worker instances process messages from a single queue without duplicating work. How does Azure Service Bus natively support this pattern?
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
✓
Service Bus automatically locks and distributes messages across competing workers using PeekLock mode.
Azure Service Bus queues inherently implement the Competing Consumers pattern. When multiple workers pull from the same queue, Service Bus locks each message to a single worker so no other worker receives it.
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 Event Hubs consumer groups with exclusive read locks.
Why it's wrong here
Event Hubs consumer groups allow multiple readers per consumer group only if assigned to separate partitions, whereas Service Bus queues distribute messages across competing consumers on a single queue.
- ✗
You must write custom distributed locking logic using Azure Blob Leases in front of the queue.
Why it's wrong here
Service Bus handles competing consumer locking natively at the broker level; blob leases are unnecessary.
- ✓
Service Bus automatically locks and distributes messages across competing workers using PeekLock mode.
Why this is correct
PeekLock ensures that when worker A grabs a message, it is locked and hidden from worker B until settled.
- ✗
You must deploy an Event Grid topic with a round-robin webhook load balancer.
Why it's wrong here
Event Grid webhooks deliver events to endpoints, whereas queues are designed for competing consumer worker pools.
