最新的Microsoft Developing Solutions for Microsoft Azure - AZ-204免費考試真題
You develop an Azure solution that uses Cosmos DB.
The current Cosmos DB container must be replicated and must use a partition key that is optimized for queries.
You need to implement a change feed processor solution.
Which change feed processor components should you use? To answer, drag the appropriate components to the correct requirements. Each component 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 the content.
NOTE: Each correct selection is worth one point.

正確答案:
Explanation:
Box 1: The monitored container
The monitored container has the data from which the change feed is generated. Any inserts and updates to the monitored container are reflected in the change feed of the container.
Box 2: The lease container
The lease container acts as a state storage and coordinates processing the change feed across multiple workers. The lease container can be stored in the same account as the monitored container or in a separate account.
Box 3: The host: A host is an application instance that uses the change feed processor to listen for changes.
Multiple instances with the same lease configuration can run in parallel, but each instance should have a different instance name.
Box 4: The delegate
The delegate is the code that defines what you, the developer, want to do with each batch of changes that the change feed processor reads.

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 to ensure security.
What should you implement? To answer, select the appropriate options in [he answer area.

Explanation:
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.

You are developing an application. You have an Azure user account that has access to two subscriptions.
You need to retrieve a storage account key secret from Azure Key Vault.
In which order should you arrange the PowerShell commands to develop the solution? To answer, move all commands from the list of commands to the answer area and arrange them in the correct order.

正確答案:
Explanation:
Step 1: Get-AzSubscription
If you have multiple subscriptions, you might have to specify the one that was used to create your key vault.
Enter the following to see the subscriptions for your account:
Get-AzSubscription
Step 2: Set-AzContext -SubscriptionId
To specify the subscription that ' s associated with the key vault you ' ll be logging, enter:
Set-AzContext -SubscriptionId < subscriptionID >
Step 3: Get-AzStorageAccountKey
You must get that storage account key.
Step 4: $secretvalue = ConvertTo-SecureString < storageAccountKey > -AsPlainText -Force Set-AzKeyVaultSecret -VaultName < vaultName > -Name < secretName > -SecretValue $secretvalue After retrieving your secret (in this case, your storage account key), you must convert that key to a secure string, and then create a secret with that value in your key vault.
Step 5: Get-AzKeyVaultSecret
Next, get the URI for the secret you created. You ' ll need this URI in a later step to call the key vault and retrieve your secret. Run the following PowerShell command and make note of the ID value, which is the secret ' s URI:
Get-AzKeyVaultSecret -VaultName < vaultName >

You are configuring a new development environment for a Java application.
The environment requires a Virtual Machine Scale Set (VMSS), several storage accounts, and networking components.
The VMSS must not be created until the storage accounts have been successfully created and an associated load balancer and virtual network is configured.
How should you complete the Azure Resource Manager template? To answer, select the appropriate options in the answer area.

Explanation:
Box 1: copyIndex
Notice that the name of each resource includes the copyIndex() function, which returns the current iteration in the loop. copyIndex() is zero-based.
Box 2: copy
By adding the copy element to the resources section of your template, you can dynamically set the number of resources to deploy.
Box 3: dependsOn
Example:
" type " : " Microsoft.Compute/virtualMachineScaleSets " ,
" apiVersion " : " 2020-06-01 " ,
" name " : " [variables( ' namingInfix ' )] " ,
" location " : " [parameters( ' location ' )] " ,
" sku " : {
" name " : " [parameters( ' vmSku ' )] " ,
" tier " : " Standard " ,
" capacity " : " [parameters( ' instanceCount ' )] "
},
" dependsOn " : [
" [resourceId( ' Microsoft.Network/loadBalancers ' , variables( ' loadBalancerName ' ))] " ,
" [resourceId( ' Microsoft.Network/virtualNetworks ' , variables( ' virtualNetworkName ' ))] "
],

You develop a software as a service (SaaS) offering to manage photographs. Users upload photos to a web service which then stores the photos in Azure Storage Blob storage. The storage account type is General- purpose V2.
When photos are uploaded, they must be processed to produce and save a mobile-friendly version of the image. The process to produce a mobile-friendly version of the image must start in less than one minute.
You need to design the process that starts the photo processing.
Solution: Create an Azure Function app that uses the Consumption hosting model and that is triggered from the blob upload.

* 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
