HOTSPOT You have an Azure Web app that uses Cosmos DB as a data store. You create a CosmosDB container by running the following PowerShell script: $resourceGroupName = "testResourceGroup" $accountName = "testCosmosAccount" $databaseName = "testDatabase" $containerName = "testContainer" $partitionKeyPath = "/EmployeeId" $autoscaleMaxThroughput = 5000 New-AzCosmosDBSqlContainer -ResourceGroupName $resourceGroupName -AccountName $accountName -DatabaseName $databaseName -Name $containerName -PartitionKeyKind Hash -PartitionKeyPath $partitionKeyPath -AutoscaleMaxThroughput $autoscaleMaxThroughput You create the following queries that target the container: SELECT * FROM c WHERE c.EmployeeId > '12345' SELECT * FROM c WHERE c.UserID = '12345' For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.
HOTSPOT You develop an application that sells Al generated images based on user input. You recently started a marketing campaign that displays unique ads every second day. Sales data is stored in Azure Cosmos DB with the date of each sale being stored in a property named 'whenFinished'. The marketing department requires a view that shows the number of sales for each unique ad. You need to implement the query for the view. How should you complete the query? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
You need to audit the retail store sales transactions. What are two possible ways to achieve the goal? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You deploy an Azure Container Apps app and disable ingress on the container app. Users report that they are unable to access the container app. You investigate and observe that the app has scaled to 0 instances. You need to resolve the issue with the container app. Solution: Enable ingress, create a TCP scale rule, and apply the rule to the container app. Does the solution meet the goal?
You are developing a road tollway tracking application that sends tracking events by using Azure Event Hubs using premium tier. Each road must have a throttling policy uniquely assigned. You need to configure the event hub to allow for per-road throttling. What should you do?
HOTSPOT You plan to implement an Azure Functions app. The Azure Functions app has the following requirements: * Must be triggered by a message placed in an Azure Storage queue. * Must use the queue name set by an app setting named input-queue. * Must create an Azure Blob Storage named the same as the content of the message. You need to identify how to reference the queue and blob name in the function. Just file of the Azure Functions app. How should you reference the names? To answer, select the appropriate values in the answer area. NOTE: Each correct selection is worth one point.

A single device can produce 2 megabytes (MB) of data every 24 hours. Each store location has one to five devices that send data. You must store the device data in Azure Blob storage. Device data must be correlated based on a device identifier. Additional stores are expected to open in the future. You need to implement a solution to receive the device data. Solution: Provision an Azure Event Grid. Configure the machine identifier as the partition key and enable capture. Does the solution meet the goal?

Question 162 - AZ-204 discussion

Report
Export

You are developing an application that uses Azure Blob storage.

The application must read the transaction logs of all the changes that occur to the blobs and the blob metadata in the storage account for auditing purposes. The changes must be in the order in which they occurred, include only create, update, delete, and copy operations and be retained for compliance reasons.

You need to process the transaction logs asynchronously.

What should you do?

A.
Process all Azure Blob storage events by using Azure Event Grid with a subscriber Azure Function app.
Answers
A.
Process all Azure Blob storage events by using Azure Event Grid with a subscriber Azure Function app.
B.
Enable the change feed on the storage account and process all changes for available events.
Answers
B.
Enable the change feed on the storage account and process all changes for available events.
C.
Process all Azure Storage Analytics logs for successful blob events.
Answers
C.
Process all Azure Storage Analytics logs for successful blob events.
D.
Use the Azure Monitor HTTP Data Collector API and scan the request body for successful blob events.
Answers
D.
Use the Azure Monitor HTTP Data Collector API and scan the request body for successful blob events.
Suggested answer: B

Explanation:

Change feed support in Azure Blob Storage The purpose of the change feed is to provide transaction logs of all the changes that occur to the blobs and the blob metadata in your storage account. The change feed provides ordered, guaranteed, durable, immutable, read-only log of these changes. Client applications can read these logs at any time, either in streaming or in batch mode. The change feed enables you to build efficient and scalable solutions that process change events that occur in your Blob Storage account at a low cost.
