Actual exam question from Microsoft's AZ-204

Question #: 12
Topic #: 6

HOTSPOT -
You are creating an app that uses Event Grid to connect with other services. Your app's event data will be sent to a serverless function that checks compliance.
This function is maintained by your company.
You write a new event subscription at the scope of your resource. The event must be invalidated after a specific period of time.
You need to configure Event Grid.
What should you do? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

Show Suggested Answer

Suggested Answer:

Box 1: SAS tokens -
Custom topics use either Shared Access Signature (SAS) or key authentication. Microsoft recommends SAS, but key authentication provides simple programming, and is compatible with many existing webhook publishers.
In this case we need the expiration time provided by SAS tokens.

Box 2: ValidationCode handshake -
Event Grid supports two ways of validating the subscription: ValidationCode handshake (programmatic) and ValidationURL handshake (manual).
If you control the source code for your endpoint, this method is recommended.
Incorrect Answers:
ValidationURL handshake (manual): In certain cases, you can't access the source code of the endpoint to implement the ValidationCode handshake. For example, if you use a third-party service (like Zapier or IFTTT), you can't programmatically respond with the validation code.

Had this question in today's exam: 2023-07-26. I think the drop-downs were in the order they are here, not 100% on it though. I went with the recommended answer anyway. Passed 940.

1. For Webhook event delivery, you should configure: a. SAS tokens: Shared Access Signature (SAS) tokens are used to grant limited access to resources in your Azure account. In the context of Event Grid, SAS tokens can be used to authenticate the webhook endpoint. 2. For Topic publishing, you should configure: a. Validation code handshake: When you subscribe to a topic, Event Grid sends a validation event to the endpoint. To complete the handshake, the endpoint must respond with the validation code. This ensures that the endpoint is ready to receive events.

So what's the answer? Keys or tokens? Keys are from SAS too. SAS token can be expired after "specific period of time".

Topic publishing to be matched with the 1st dropdown....the answer must be Management Access Control. Azure Event Grid allows you to control the level of access given to different users to do various management operations such as list event subscriptions, create new ones, and generate keys. Event Grid uses Azure's role-based access control (RBAC).

This question is worded poorly, the handshake only happens when subscription is setup ... If you are talking about how subscription should be authenticated when receiving messages, then webhook should use jwt
