You are implementing an application by using Azure Event Grid to push near-real-time information to customers.

You have the following requirements:

• You must send events to thousands of customers that include hundreds of various event types.

• The events must be filtered by event type before processing.

• Authentication and authorization must be handled by using Microsoft Entra ID.

• The events must be published to a single endpoint.

You need to implement Azure Event Grid.

Solution: Publish events to an event domain. Create a custom topic for each customer.

Background

Fourth Coffee is a global coffeehouse chain and coffee company recognized as one of the world’s most influential coffee brands. The company is renowned for its specialty coffee beverages, including a wide range of espresso-based drinks, teas, and other beverages. Fourth Coffee operates thousands of stores worldwide.

Current environment

The company is developing cloud-native applications hosted in Azure.

Corporate website

The company hosts a public website located at http://www.fourthcoffee.com/. The website is used to place orders as well as view and update inventory items.

Inventory items

In addition to its core coffee offerings, Fourth Coffee recently expanded its menu to include inventory items such as lunch items, snacks, and merchandise. Corporate team members constantly update inventory. Users can customize items. Corporate team members configure inventory items and associated images on the website.

Orders

Associates in the store serve customized beverages and items to customers. Orders are placed on the website for pickup.

The application components process data as follows:

1. Azure Traffic Manager routes a user order request to the corporate website hosted in Azure App Service.

2. Azure Content Delivery Network serves static images and content to the user.

3. The user signs in to the application through a Microsoft Entra ID for customers tenant.

4. Users search for items and place an order on the website as item images are pulled from Azure Blob Storage.

5. Item customizations are placed in an Azure Service Bus queue message.

6. Azure Functions processes item customizations and saves the customized items to Azure Cosmos DB.

7. The website saves order details to Azure SQL Database.

8. SQL Database query results are cached in Azure Cache for Redis to improve performance.

The application consists of the following Azure services:

Requirements

The application components must meet the following requirements:

• Azure Cosmos DB development must use a native API that receives the latest updates and stores data in a document format.

• Costs must be minimized for all Azure services.

• Developers must test Azure Blob Storage integrations locally before deployment to Azure. Testing must support the latest versions of the Azure Storage APIs.

Corporate website

• User authentication and authorization must allow one-time passcode sign-in methods and social identity providers (Google or Facebook).

• Static web content must be stored closest to end users to reduce network latency.

Inventory items

• Customized items read from Azure Cosmos DB must maximize throughput while ensuring data is accurate for the current user on the website.

• Processing of inventory item updates must automatically scale and enable updates across an entire Azure Cosmos DB container.

• Inventory items must be processed in the order they were placed in the queue.

• Inventory item images must be stored as JPEG files in their native format to include exchangeable image file format (data) stored with the blob data upon upload of the image file.

• The Inventory Items API must securely access the Azure Cosmos DB data.

Orders

• Orders must receive inventory item changes automatically after inventory items are updated or saved.

Issues

• Developers are storing the Azure Cosmos DB credentials in an insecure clear text manner within the Inventory Items API code.

• Production Azure Cache for Redis maintenance has negatively affected application performance.

You need to implement a function by using Azure Functions to process customized items.

How should you implement the function? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

A large retail company operates online and physical stores. The company tracks inventory levels in real time to manage stock efficiently across all locations. You develop an Azure Event Grid solution to handle events generated by the inventory management system deployed to Azure.

You need to implement a subscription filter that dynamically adjusts to seasonal changes in product demand.

Which event filter should you use?

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

You are developing an application that needs to react to events from multiple Azure services, such as Azure Blob Storage and Azure Resource Manager, in near-real time.

The application must meet the following requirements:

• Handle a high volume of events without manual intervention.

• Receive only specific events relevant to your application, based on event types or resource patterns.

• Ensure that no events are missed, even if the processing application is temporarily unavailable.

• Use Azure Functions for processing events without managing any infrastructure.

• Minimize the amount of custom code required for event routing and handling.

You need to develop the solution.

Solution: Configure Azure Event Grid system topics for each Azure service. Create event subscriptions with Advanced Filters to receive only the relevant events. Use Azure Functions with Event Grid triggers to process the events. Enable Dead-lettering on the event subscriptions to handle failures and ensure reliable delivery.

Does the solution meet the goal?

You need to add code at line PC32 in Processing.cs to implement the GetCredentials method in the Processing class.

How should you complete the code? To answer, drag the appropriate code segments to the correct locations. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.
