You are a developer implementing highly scalable and resilient applications to support online order processing by using Azure solutions. Coho Winery has a LabelMaker application that prints labels for wine bottles. The application sends data to several printers. The application consists of five modules that run independently on virtual machines (VMs). Coho Winery plans to move the application to Azure and continue to support label creation. External partners send data to the LabelMaker application to include artwork and text for custom label designs. Requirements. Data You identify the following requirements for data management and manipulation: ✑ Order data is stored as nonrelational JSON and must be queried using SQL. ✑ Changes to the Order data must reflect immediately across all partitions. All reads to the Order data must fetch the most recent writes. Requirements. Security You have the following security requirements: ✑ Users of Coho Winery applications must be able to provide access to documents, resources, and applications to external partners. ✑ External partners must use their own credentials and authenticate with their organization’s identity management solution. ✑ External partner logins must be audited monthly for application use by a user account administrator to maintain company compliance. ✑ Storage of e-commerce application settings must be maintained in Azure Key Vault. ✑ E-commerce application sign-ins must be secured by using Azure App Service authentication and Azure Active Directory (AAD). ✑ Conditional access policies must be applied at the application level to protect company content. ✑ The LabelMaker application must be secured by using an AAD account that has full access to all namespaces of the Azure Kubernetes Service (AKS) cluster. Requirements. LabelMaker app Azure Monitor Container Health must be used to monitor the performance of workloads that are deployed to Kubernetes environments and hosted on Azure Kubernetes Service (AKS). You must use Azure Container Registry to publish images that support the AKS deployment. Architecture Issues Calls to the Printer API App fail periodically due to printer communication timeouts. Printer communication timeouts occur after 10 seconds. The label printer must only receive up to 5 attempts within one minute. The order workflow fails to run upon initial deployment to Azure. Order.json Relevant portions of the app files are shown below. Line numbers are included for reference only. This JSON file contains a representation of the data for an order that includes a single item. Order.json DRAG DROP You need to deploy a new version of the LabelMaker application to ACR. Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Explanation: A picture containing timeline Description automatically generated Step 1: Build a new application image by using dockerfile Step 2: Create an alias if the image with the fully qualified path to the registry Before you can push the image to a private registry, you’ve to ensure a proper image name. This can be achieved using the docker tag command. For demonstration purpose, we’ll use Docker’s hello world image, rename it and push it to ACR. # pulls hello-world from the public docker hub $ docker pull hello-world # tag the image in order to be able to push it to a private registry $ docker tag hello-word <REGISTRY_NAME>/hello-world # push the image $ docker push <REGISTRY_NAME>/hello-world Step 3: Log in to the registry and push image In order to push images to the newly created ACR instance, you need to login to ACR form the Docker CLI. Once logged in, you can push any existing docker image to your ACR instance. Scenario: Coho Winery plans to move the application to Azure and continue to support label creation. LabelMaker app Azure Monitor Container Health must be used to monitor the performance of workloads that are deployed to Kubernetes environments and hosted on Azure Kubernetes Service (AKS). You must use Azure Container Registry to publish images that support the AKS deployment.
You need to resolve the capacity issue. What should you do?
Explanation: If you want to read the files in parallel, you cannot use forEach. Each of the async callback function calls does return a promise. You can await the array of promises that you'll get with Promise.all. Scenario: Capacity issue: During busy periods, employees report long delays between the time they upload the receipt and when it appears in the web application.

You need to ensure the security policies are met. What code do you add at line CS07 of ConfigureSSE.ps1?
Explanation: Scenario: All certificates and secrets used to secure data must be stored in Azure Key Vault. You must adhere to the principle of least privilege and provide privileges which are essential to perform the intended function. The Set-AzureRmKeyValutAccessPolicy parameter -PermissionsToKeys specifies an array of key operation permissions to grant to a user or service principal. The acceptable values for this parameter: decrypt, encrypt, unwrapKey, wrapKey, verify, sign, get, list, update, create, import, delete, backup, restore, recover, purge Reference: https://docs.microsoft.com/en-us/powershell/module/azurerm.keyvault/set-azurermkeyvaultaccesspolicy
DRAG DROP You need to ensure disaster recovery requirements are met. What code should you add at line PC16? To answer, drag the appropriate code fragments to the correct locations. Each code fragment 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.
Explanation: Scenario: Disaster recovery. Regional outage must not impact application availability. All DR operations must not be dependent on application running and must ensure that data in the DR region is up to date. Box 1: DirectoryTransferContext We transfer all files in the directory. Note: The TransferContext object comes in two forms: SingleTransferContext and DirectoryTransferContext. The former is for transferring a single file and the latter is for transferring a directory of files. Box 2: ShouldTransferCallbackAsync The DirectoryTransferContext.ShouldTransferCallbackAsync delegate callback is invoked to tell whether a transfer should be done. Box 3: False If you want to use the retry policy in Copy, and want the copy can be resume if break in the middle, you can use SyncCopy (isServiceCopy = false). Note that if you choose to use service side copy ('isServiceCopy' set to true), Azure (currently) doesn't provide SLA for that. Setting 'isServiceCopy' to false will download the source blob loca
DRAG DROP 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.
Explanation: Box 1: AzureServiceTokenProvider() Box 2: tp.GetAccessTokenAsync("..") Acquiring an access token is then quite easy. Example code: private async Task<string> GetAccessTokenAsync() { var tokenProvider = new AzureServiceTokenProvider(); return await tokenProvider.GetAccessTokenAsync("https://storage.azure.com/"); }
