You have a web service that is used to pay for food deliveries. The web service uses Azure Cosmos DB as the data store.You plan to add a new feature that allows users to set a tip amount. The new feature requires that a property named tip on the document in Cosmos DB must be present and contain a numeric value.There are many existing websites and mobile apps that use the web service that will not be updated to set the tip property for some time.How should you complete the trigger?NOTE: Each correct selection is worth one point

• Box1:_.value();

  Box2:if(isNan(i)["tip"]||i["tip"]===null){

  Box3:r.setValue(i);

• Box1:getContext().getRequest();

  Box2:if(isNan(i)["tip"]||i["tip"]===null){

  Box3:r.setBody(i);

• Box1:getContext().getResponse();

  Box2:if(isNan(i)["tip"]||i["tip"]===null){

  Box3:_upsertDocument(i);

You develop an HTTP triggered Azure Function app to process Azure Storage blob data. The app is triggered using an output binding on the blob.The app continues to time out after four minutes. The app must process the blob data.You need to ensure the app does not time out and processes the blob data.Solution: Use the Durable Function async pattern to process the blob data.Does the solution meet the goal?

• Yes

• No

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 AzureStorage 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: Move photo processing to an Azure Function triggered from the blob upload.Does the solution meet the goal?

• YES

• NO

Answer explanation

Azure Storage events allow applications to react to events. Common Blob storage event scenarios include image or video processing, search indexing, or any file- oriented workflow.Events are pushed using Azure Event Grid to subscribers such as Azure Functions, Azure Logic Apps, or even to your own http listener.Note: Only storage accounts of kind StorageV2 (general purpose v2) and BlobStorage support event integration. Storage (general purpose v1) does not support integration with Event Grid.Reference:https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-overview

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?

• Process all Azure Blob storage events by using Azure Event Grid with a subscriber Azure Function app.

• Enable the change feed on the storage account and process all changes for available events

• Process all Azure Storage Analytics logs for successful blob events.

• Use the Azure Monitor HTTP Data Collector API and scan the request body for successful blob events.

Answer explanation

Change feed support in Azure Blob StorageThe 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.Reference:https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-change-feed

You plan to create a Docker image that runs an ASP.NET Core application named ContosoApp. You have a setup script named setupScript.ps1 and a series of application files including ContosoApp.dll.You need to create a Dockerfile document that meets the following requirements:✑ Call setupScripts.ps1 when the container is built.✑ Run ContosoApp.dll when the container starts.The Dockerfile document must be created in the same folder where ContosoApp.dll and setupScript.ps1 are stored.Which five commands should you use to develop the solution? To answer, move the appropriate commands from the list of commands to the answer area and arrange them in the correct order.

• Box 1: COPY ./ .

  Box 2: FROM

  Box 3: WORKDIR /apps/ContosoApp -Bxo 4: CMD [..]

  Box 5: RUN powershell ./setupScript.ps1

• Box 1: WORKDIR /apps/ContosoApp -Bxo

  Box 2: FROM

  Box 3:CMD [..]

  Box 4: COPY ./ .

  Box 5: RUN powershell ./setupScript.ps1

• Box 1: CMD [..]

  Box 2: FROM

  Box 3: WORKDIR /apps/ContosoApp -Bxo 4: COPY ./ .

  Box 5: RUN powershell ./setupScript.ps1

You are developing an Azure Function App that processes images that are uploaded to an Azure Blob container.Images must be processed as quickly as possible after they are uploaded, and the solution must minimize latency. You create code to process images when theFunction App is triggered.You need to configure the Function App.What should you do?

• Use an App Service plan. Configure the Function App to use an Azure Blob Storage input trigger.

• Use a Consumption plan. Configure the Function App to use an Azure Blob Storage trigger.

• Use a Consumption plan. Configure the Function App to use a Timer trigger.

• Use an App Service plan. Configure the Function App to use an Azure Blob Storage trigger.

• Use a Consumption plan. Configure the Function App to use an Azure Blob Storage input trigger.

Answer explanation

Correct Answer: D

The Blob storage trigger starts a function when a new or updated blob is detected. The blob contents are provided as input to the function.The Consumption plan limits a function app on one virtual machine (VM) to 1.5 GB of memory.Reference:https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-trigger

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?

Answer 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'))]"],Reference:https://docs.microsoft.com/en-us/azure/azure-resource-manager/templates/copy-resources https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/quick-create-template-windows
