CV0-004 Deployment Practice Question
A cloud architect is designing a serverless application using Azure Functions. The function must process messages from an Azure Storage Queue. How should the architect configure the trigger?
⚠ Common exam trap
CompTIA Cloud+ candidates often mistakenly choose Event Grid because it is event-driven, but it does not directly integrate with Storage Queues without custom event subscriptions.
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
✓
Queue trigger
Azure Functions natively supports a Queue trigger that automatically polls an Azure Storage Queue for new messages and executes the function code when a message is detected. This is the simplest and most efficient way to process messages from a Storage Queue without custom polling logic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Blob trigger
Why it's wrong here
Blob trigger responds to blob storage events, not queue messages.
- ✗
Event Grid trigger
Why it's wrong here
Event Grid can route queue messages but is not the direct trigger for Storage Queues.
- ✓
Queue trigger
Why this is correct
Queue trigger is designed for Azure Storage Queue messages.
- ✗
HTTP trigger with queue polling
Why it's wrong here
HTTP trigger is for web requests; queue polling is not built-in.
