A Service Bus-triggered function must process at most 4 messages concurrently per instance. Where is this configured?
- A In the function signature
- B maxConcurrentCalls in host.json under the serviceBus extension (correct answer)
- C In the connection string
- D In the Service Bus queue properties
Shortcut: json controls extension concurrency. Setting maxConcurrentCalls bounds parallel message handling per instance, which protects downstream dependencies.
