Exam AZ-204 topic 1 question 31 discussion

Only C is mentioned both topic and subscription, which are two critical parts for event grid, so I will go C, anyway, this question is very poorly worded

For your interest, please see https://docs.microsoft.com/en-us/azure/event-grid/event-filtering Correct answer is D.

The requirement states that sign-out events must be processed as fast as possible while ensuring that all authentication events are processed by PolicyApp. Azure Event Grid allows filtering of events based on subject prefixes using the subjectBeginsWith filter. By adding a subject prefix to sign-out events (e.g., /auth/signout), you can create a subscription that only processes sign-out events separately, ensuring faster processing. Sign-in events can be handled by a separate general subscription that processes all authentication events.

Answer should be D, to cross verify I used Copilot and Gemini and both accept D

D

Since sign-out events need to be processed as quickly as possible, having a dedicated topic and subscription for them ensures they are not delayed by sign-in events or other types of events.

Answer is D. All authentication events are processed by PolicyApp. By adding a subject prefix to unsubscribe events and using the filter, unsubscribe events can be quickly identified and prioritized. Meets both requirements: All events are processed by PolicyApp. Unsubscribe events are processed as quickly as possible.

The answer is correct, Option B creates a separate Azure subscription for sign-in and sign-out events implying that two event types are required, subject prefix just require one event type for sign-in and sign-out events.

First, the answers are poorly written. To process sign-outs fasters, we will have to do parallel processing. (there is no priority assignment in Event Grid) Ideal solution would be to create one topic and 2 different subscriptions - a) without any filter b) another with just sign-out filter Option D has 2 issues - a) It expects change to the external app i.e. Azure App Service Web App (remember you are developing PolicyApp not the app being monitored) to log the sign-out event with a prefix. b) It only takes care of Sign-out events. To cater to all events, you would need yet another subscription. I don't like C either. One doesn't need different Topic as it could also mean impact to the application ingesting these events to split the events to 2 different topics. C is inefficient way to solve the problem.

By creating dedicated topics (and corresponding subscriptions) for sign-out events, you ensure that these events can be processed immediately and without the overhead of filtering from a mixed set of authentication events. This approach provides a clear and direct path for sign-out events to be handled, potentially reducing processing time and meeting the prioritization requirement.

The "All authentication events must be processed by PolicyApp clause" should avoid C, so is D

Filtering is something that you can use regardless (which adds a small overhead though). But the question says "sign-outs should be as fast as possible" which means creating a dedicated topic only for "sign-outs" is the best possible solution.

The correct answer is C

Answer is D

It's C

I think i have seen this before and the answer was C on that practice test.

"chatgpt" The requirement is to process authentication events, specifically sign-in and sign-out, and make sure that sign-outs are processed as quickly as possible. You want to be able to filter events specifically for this purpose. Option D will fulfill these requirements. By adding a subject prefix to sign-out events and creating an Azure Event Grid subscription that is configured to use the subjectBeginsWith filter, you can specifically target and process the sign-out events quickly. The subjectBeginsWith filter allows for efficient filtering of events, which aligns with the requirement of processing sign-outs as fast as possible. Therefore, the correct answer is: D. Add a subject prefix to sign-out events. Create an Azure Event Grid subscription. Configure the subscription to use the subjectBeginsWith filter.
