AI-200 Event Driven Integration Practice Question
You are configuring an Azure Event Grid system to route custom application events to an Azure Function webhook. To ensure secure communication, you decide to use Event Grid custom topics with Azure AD authentication. Which configuration step is required on the Azure Function endpoint to authenticate incoming events from Event Grid?
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
✓
Implement validation handshake logic in the Azure Function code to respond to the Event Grid subscription validation event.
Azure Event Grid supports Webhook validation handshake by sending a Subscription Validation Event containing a validation code, which the webhook endpoint must echo back.
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 the Azure Function app with an Event Grid system-assigned managed identity and grant it the Event Grid Data Sender role.
Why it's wrong here
The sender (Event Grid) needs authentication to the destination, not the destination sending to the sender.
- ✗
Install the Microsoft.Azure.EventGrid NuGet package and configure a SAS token generated from the Function App settings.
Why it's wrong here
SAS tokens are used for publishing events to topics, not for validating webhook delivery endpoints.
- ✗
Enable mutual TLS (mTLS) authentication on the Azure Function App and upload the Event Grid root CA certificate.
Why it's wrong here
Event Grid webhooks use validation handshakes and optional AAD or secret headers, not mTLS client certificate uploads.
- ✓
Implement validation handshake logic in the Azure Function code to respond to the Event Grid subscription validation event.
Why this is correct
Endpoints must validate their ownership by responding to the validation handshake request sent by Event Grid upon creation.
