  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>

• Question 33:

  You are developing an application to store business-critical data in Azure Blob storage. The application must meet the following requirements:

  1. Data must not be modified or deleted for a user-specified interval.

  2. Data must be protected from overwntes and deletes.

  3. Data must be written once and allowed to be read many times.

  You need to protect the data fen the Azure Blob storage account.

  Which two actions should you perform? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. Configure a time-based retention policy for the storage account.
  B. Create an account shared-access signature (SAS).
  C. Enable the blob change feed for the storage account.
  D. Enable version-level immutability support for the storage account.
  E. Enable point-in-time restore for containers in the storage account.
  F. Create a service shared-access signature (SAS).
  A. Configure a time-based retention policy for the storage account.
  D. Enable version-level immutability support for the storage account.

  ---

  Explanation

  A. Configure a time-based retention policy for the storage account - A time-based retention policy stores blob data in a Write-Once, Read-Many (WORM) format for a specified interval. When a time-based retention policy is set, clients can create and read blobs, but can't modify or delete them. After the retention interval has expired, blobs can be deleted but not overwritten.

  D. Before you can apply a time-based retention policy to a blob version, you must enable support for version-level immutability.

• Question 34:

  HOTSPOT

  You need to implement the delivery service telemetry data.

  How should you configure the solution? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection is worth one point.

  

  

  ---

  Box 1: Core SQL

  SQL API: Serverless database computing using Azure Cosmos DB and Azure Functions.

  Note: Store service telemetry data in Azure Cosmos DB by using an Azure Function. Data must include an item id, the delivery vehicle license plate, vehicle package capacity, and current vehicle location coordinates.

  Box 2: Vehicle license plate

  Selecting your partition key is a simple but important design choice in Azure Cosmos DB. Once you select your partition key, it is not possible to change it in-place. If you need to change your partition key, you should move your data to a new container with your new desired partition key.

  For all containers, your partition key should:

  Be a property that has a value which does not change. If a property is your partition key, you can't update that property's value.

  Have a high cardinality. In other words, the property should have a wide range of possible values.

  Spread request unit (RU) consumption and data storage evenly across all logical partitions. This ensures even RU consumption and storage distribution across your physical partitions.

  Note: The company supports thousands of store locations globally. Store locations send data every hour to an Azure Blob storage account to support inventory, purchasing and delivery services. Each record includes a location identifier and sales transaction information.

• Question 35:

  The solution must receive and store messages until they can be processed. You create an Azure Service Bus instance by providing a name, pricing tier, subscription, resource group, and location.

  You need to complete the configuration.

  Which Azure CLI or PowerShell command should you run?

  A. New-AzureRmResourceGroup -Name fridge-rg -Location fridge-loc
  B. connectionStrings=$(az servicebus namespace authorization-rule keys list \ --resource-group fridge-rg \ --namespace-name fridge-ns \ --name RootManageSharedAccessKey \ --query primaryConnectionString --output tsv)
  C. New-AzureRmServiceBusQueue \ -ResourceGroupName fridge-rg \ -NamespaceName fridge-ns \ -Name fridge-q \ -EnablePartitioning $False
  D. New-AzureRmServiceBusNamespace \ -ResourceGroupName fridge-rg \ -NamespaceName fridge-ns \ -Location fridge-loc
  D. New-AzureRmServiceBusNamespace \ -ResourceGroupName fridge-rg \ -NamespaceName fridge-ns \ -Location fridge-loc

• Question 36:

  HOTSPOT

  You have an Azure subscription that hosts an Application Insights workspace named Workspace1.

  You plan to aulhoi .Net-based code and deploy it to an App Service Web App named App1. Telemetry generated by Appl will be ingested into Workspace1.

  You intend to use Microsoft Entra ID authentication and Azure role-based access control (RBAC) to prevent unauthorized telemetry from being ingested into Workspacel.

  You need to configure the Entra ID credential class and the RBAC role for App1.

  What should you configure? To answer, select the appropriate options in the answer area.

  NOTE: Each correct selection Is worth one point.

  

  

• Question 37:

  You have an existing Azure storage account that stores large volumes of data across multiple containers.

  You need to copy all data from the existing storage account to a new storage account. The copy process must meet the following requirements:

  1. Automate data movement.

  2. Minimize user input required to perform the operation. Ensure that the data movement process is recoverable.

  What should you use?

  A. AzCopy
  B. Azure Storage Explorer
  C. Azure portal
  D. .NET Storage Client Library
  A. AzCopy

  ---

  Explanation

  You can copy blobs, directories, and containers between storage accounts by using the AzCopy v10 command-line utility.

  The copy operation is synchronous so when the command returns, that indicates that all files have been copied.

• Question 38:

  DRAG DROP

  You are developing a solution for a hospital to support the following use cases:

  1. The most recent patient status details must be retrieved even if multiple users in different locations have updated the patient record.

  2. Patient health monitoring data retrieved must be the current version or the prior version.

  3. After a patient is discharged and all charges have been assessed, the patient billing record contains the final charges.

  You provision a Cosmos D6 NoSQL database and set the default consistency level for the database account to Strong.

  You set the value for Indexing Mode to Consistent.

  You need to configure the consistency levels to support each scenario.

  You must minimize latency and any impact to the availability of the solution.

  You must override the default consistency level at the query level to meet the required consistency guarantees for the scenarios.

  Which consistency levels should you implement? To answer, drag the appropriate consistency levels to the correct requirements. Each consistency level 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.

  Select and Place:

  

  

  ---

  Box 1: Strong

  Strong: Strong consistency offers a linearizability guarantee. The reads are guaranteed to return the most recent committed version of an item. A client never sees an uncommitted or partial write. Users are always guaranteed to read the latest committed write.

  Box 2: Bounded staleness

  Bounded staleness: The reads are guaranteed to honor the consistent-prefix guarantee. The reads might lag behind writes by at most "K" versions (that is "updates") of an item or by "t" time interval. When you choose bounded staleness, the "staleness" can be configured in two ways:

  The number of versions (K) of the item

  The time interval (t) by which the reads might lag behind the writes

  Box 3: Eventual

  Eventual: There's no ordering guarantee for reads. In the absence of any further writes, the replicas eventually converge.

• Question 39:

  You are creating an app that will use CosmosDB for data storage. The app will process batches of relational data.

  You need to select an API for the app.

  Which API should you use?

  A. MongoDB API
  B. Table API
  C. SQL API
  D. Cassandra API
  C. SQL API

  ---

  Explanation

  For relational data you will need the SQL API

  Incorrect Answer:

  A: The MongoDB API is not used for relational data.

  B: The Table API only supports data in the key/value format

  D: The Cassandra API only supports OLTP (Online Transactional Processing) and not batch processing.
