Q2. You need to deliver a mobile push notification feature for the Kineteco Retail app, hosted in Azure App Service. The solution should minimize cost, complexity, and development effort. Which option should you choose?

  • Notification Hub
  • Event Grid
  • Twilio
  • Service Bus

Explanation: Twilio is an SMS notification app, also not from Microsoft. Event Grid can be techincally used for this purpose but it's a more generic event-broadcasting service. Service Bus is another generic publish-subscribe solution. Finally Notification Hubs are specifically designed for push-notifications.

Q3. Your application hosted in Azure App Service needs to retrieve secrets from Azure Key Vault. Which choice is NOT a way to authenticate to Key Vault?

  • service principal and a certificate
  • managed identity
  • service principal and a secret
  • shared access key

Azure Key Vault Developer's Guide lists 3 available methods. The shared access key does not exist in Azure at all, the closest term is shared access signature (SAS) but it's used to access Azure Storage only.

Q4. You added a persistent volume claim to your apps YAML manifest. When you attempt to deploy to an existing AKS cluster there is no persistent volume available. What should you do?

  • Do nothing. The API server will provision additional storage automatically
  • Add a data disk definition for the AKS cluster to your apps YAML manifest
  • Add a data disk to each Kubernetes cluster node and reattempt app deployment
  • Provision an Azure Files instance and reattempt app deployment

Q24. You have set of SQL databases used with various PaaS applications with predictable usage patterns. You are planning to move these databases to Azure SQL and need to choose the right deployment option. Your priorities are minimizing costs, and having the ability to assign CPU and resources to individual databases. Which option should you choose?

  • Azure SQL elastic pool
  • SQL on Azure VMs
  • Azure SQL Database
  • SQL Managed Instance

Explanation: For many businesses and applications, creating individual databases and scaling performance up or down as needed is sufficient, especially when usage patterns are relatively predictable. Unpredictable usage patterns can make it difficult to manage costs and your business model. Elastic pools aim to solve this problem. Performance resources are allocated to a pool, not to a single database. You pay for the collective performance resources of the pool, not for the performance of a single database.

Q77. This question requires that you evaluate the underlined text to determine if it is correct.

An organization that hosts its infrastructure in a private cloud can close its data center. Instructions: Review the underlined text. If it makes the statement correct, select “No change is needed”. If the statement is incorrect, select the answer choice that makes the statement correct.

  • No change is needed.
  • in a hybrid cloud
  • in the public cloud
  • on a Hyper-V host

Explanation/Reference: Explanation: A private cloud is hosted in your datacenter. Therefore, you cannot close your datacenter if you are using a private cloud. A public cloud is hosted externally, for example, in Microsoft Azure. An organization that hosts its infrastructure in a public cloud can close its data center. Public cloud is the most common deployment model. In this case, you have no local hardware to manage or keep up-to-date – everything runs on your cloud provider's hardware. Microsoft Azure is an example of a public cloud provider. In a private cloud, you create a cloud environment in your own datacenter and provide self-service access to compute resources to users in your organization. This offers a simulation of a public cloud to your users, but you remain completely responsible for the purchase and maintenance of the hardware and software services you provide.

Ref

Q78.What are two characteristics of the public cloud? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

  • dedicated hardware
  • limited storage
  • metered pricing
  • self-service management
  • unsecured connections

Explanation/Reference: Explanation: With the public cloud, you get pay-as-you-go pricing – you pay only for what you use, no CapEx costs. With the public cloud, you have self-service management. You are responsible for the deployment and configuration of the cloud resources such as virtual machines or web sites. The underlying hardware that hosts the cloud resources is managed by the cloud provider. Incorrect Answers: A: You don’t have dedicated hardware. The underlying hardware is shared so you could have multiple customers using cloud resources hosted on the same physical hardware. B: Connections to the public cloud are secure. C: Storage is not limited. You can have as much storage as you like.

Ref

Q79. Your company hosts an accounting application named App1 that is used by all the customers of the

company. App1 has low usage during the first three weeks of each month and very high usage during the last week of each month. Which benefit of Azure Cloud Services supports cost management for this type of usage pattern?

  • high availabilit
  • high latency
  • elasticity
  • load balancing

Explanation/Reference: Explanation: Elasticity in this case is the ability to provide additional compute resource when needed and reduce the compute resource when not needed to reduce costs. Autoscaling is an example of elasticity. Elastic computing is the ability to quickly expand or decrease computer processing, memory and storage resources to meet changing demands without worrying about capacity planning and engineering for peak usage. Typically controlled by system monitoring tools, elastic computing matches the amount of resources allocated to the amount of resources actually needed without disrupting operations. With cloud elasticity, a company avoids paying for unused capacity or idle resources and doesn’t have to worry about investing in the purchase or maintenance of additional resources and equipment.

  • Software as a Service (SaaS)
  • Platform as a Service (PaaS)
  • Infrastructure as a Service (IaaS)
  • Database as a Service (DaaS)

Explanation/Reference: Explanation: Azure App Service is a platform-as-a-service (PaaS) offering that lets you create web and mobile apps for any platform or device and connect to data anywhere, in the cloud or on-premises.

Q81. You have an on-premises network that contains 100 servers.

You need to recommend a solution that provides additional resources to your users. The solution must minimize capital and operational expenditure costs. What should you include in the recommendation?

  • a complete migration to the public cloud
  • an additional data center
  • a private cloud
  • a hybrid cloud

Explanation/Reference: Explanation: A hybrid cloud is a combination of a private cloud and a public cloud. Capital expenditure is the spending of money up-front for infrastructure such as new servers. With a hybrid cloud, you can continue to use the on-premises servers while adding new servers in the public cloud (Azure for example). Adding new servers in Azure minimizes the capital expenditure costs as you are not paying for new servers as you would if you deployed new server on-premises. Incorrect Answers: A: A complete migration of 100 servers to the public cloud would involve a lot of operational expenditure (the cost of migrating all the servers). B: An additional data center would involve a lot of capital expenditure (the cost of the new infrastructure). C: A private cloud is hosted on on-premises servers to this would involve a lot of capital expenditure (the cost of the new infrastructure to host the private cloud

Q82. You plan to migrate several servers from an on-premises network to Azure.

What is an advantage of using a public cloud service for the servers over an on-premises network

  • The public cloud is owned by the public, NOT a private corporation
  • The public cloud is a crowd-sourcing solution that provides corporations with the ability to enhance the cloud
  • The public cloud is a shared entity whereby multiple corporations each use a portion of the resources in the cloud
  • All public cloud resources can be freely accessed by every member of the public

Explanation/Reference: Explanation: The public cloud is a shared entity whereby multiple corporations each use a portion of the resources in the cloud. The hardware resources (servers, infrastructure etc.) are managed by the cloud provider. Multiple companies create resources such as virtual machines and virtual networks on the hardware resources. Incorrect Answers: A: The public cloud is not owned by the public. In the case of Microsoft Azure, the cloud is owned by Microsoft. B: The public cloud is a not crowd-sourcing solution. In the case of Microsoft Azure, the cloud is owned by Microsoft. C: It is not true that public cloud resources can be freely accessed by every member of the public. You pay for a cloud subscription and create accounts for your users to access your cloud resources. No one can access your cloud resources until you create user accounts and provide the appropriate access permissions.

Q83. You have 1,000 virtual machines hosted on the Hyper-V hosts in a data center.

You plan to migrate all the virtual machines to an Azure pay-as-you-go subscription. You need to identify which expenditure model to use for the planned Azure solution. Which expenditure model should you identify?

  • operational
  • elastic
  • capital
  • scalable

Explanation/Reference: Explanation: One of the major changes that you will face when you move from on-premises cloud to the public cloud is the switch from capital expenditure (buying hardware) to operating expenditure (paying for service as you use it). This switch also requires more careful management of your costs. The benefit of the cloud is that you can fundamentally and positively affect the cost of a service you use by merely shutting down or resizing it when it's not needed.

Q84. Your company has an on-premises network that contains multiple servers.

The company plans to reduce the following administrative responsibilities of network administrators: Backing up application data Replacing failed server hardware Managing physical server security Updating server operating systems Managing permissions to shared documents The company plans to migrate several servers to Azure virtual machines. You need to identify which administrative responsibilities will be eliminated after the planned migration. Which two responsibilities should you identify? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

  • Replacing failed server hardware
  • Backing up application data
  • Updating server operating systems
  • Managing permissions to shared documents

Explanation/Reference: Explanation: Azure virtual machines run on Hyper-V physical servers. The physical servers are owned and managed by Microsoft. As an Azure customer, you have no access to the physical servers. Microsoft manage the replacement of failed server hardware and the security of the physical servers so you don’t need to. Incorrect Answers: B: Microsoft have no control over the applications you run on the virtual machines. Therefore, it is your responsibility to ensure that application data is backed up. D: Microsoft do not manage the operating systems you run on the virtual machines. Therefore, it is your responsibility to ensure that the operating systems are updated. E: Microsoft have no control over the shared folders you host on the virtual machines. Therefore, it is your responsibility to ensure that folder permissions are configured appropriately.

Q85. A team of developers at your company plans to deploy, and then remove, 50 virtual machines each week. All the virtual machines are configured by using Azure Resource Manager templates.

You need to recommend which Azure service will minimize the administrative effort required to deploy and remove the virtual machines. What should you recommend?

  • Azure Reserved Virtual Machine (VM) Instances
  • Azure DevTest Labs
  • Azure virtual machine scale sets
  • Microsoft Managed Desktop

Explanation/Reference: Explanation: DevTest Labs creates labs consisting of pre-configured bases or Azure Resource Manager templates. By using DevTest Labs, you can test the latest versions of your applications by doing the following tasks: Quickly provision Windows and Linux environments by using reusable templates and artifacts. Easily integrate your deployment pipeline with DevTest Labs to provision on-demand environments. Scale up your load testing by provisioning multiple test agents and create pre-provisioned environments for training and demos.

Q86. You use Azure Table storage to store customer information for an application. The data contains customer details and is partitioned by last name. You need to

create a query that returns all customers with the last name Smith. Which code segment should you use?

  • TableQuery.GenerateFilterCondition("PartitionKey", Equals, "Smith")
  • TableQuery.GenerateFilterCondition("LastName", Equals, "Smith")
  • TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "Smith")
  • TableQuery.GenerateFilterCondition("LastName", QueryComparisons.Equal, "Smith")

Explanation: Retrieve all entities in a partition. The following code example specifies a filter for entities where 'Smith' is the partition key. This example prints the fields of each entity in the query results to the console. Construct the query operation for all customer entities where PartitionKey="Smith". TableQuery query = new TableQuery().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "Smith"));

Q87.You develop an app that allows users to upload photos and videos to Azure storage. The app uses a storage REST API call to upload the media to a blob storage

account named Account1. You have blob storage containers named Container1 and Container2. Uploading of videos occurs on an irregular basis. You need to copy specific blobs from Container1 to Container2 in real time when specific requirements are met, excluding backup blob copies. What should you do?

  • Download the blob to a virtual machine and then upload the blob to Container2.
  • Run the Azure PowerShell command Start-AzureStorageBlobCopy
  • Copy blobs to Container2 by using the Put Blob operation of the Blob Service REST API.
  • Use AzCopy with the Snapshot switch blobs to Container2.

Explanation: The Start-AzureStorageBlobCopy cmdlet starts to copy a blob. Example 1: Copy a named blob C:\PS>Start-AzureStorageBlobCopy -SrcBlob "ContosoPlanning2015" -DestContainer "ContosoArchives" -SrcContainer "ContosoUploads" This command starts the copy operation of the blob named ContosoPlanning2015 from the container named ContosoUploads to the container named ContosoArchives.

Q89.You are developing an Azure Cosmos DB solution by using the Azure Cosmos DB SQL API. The data includes millions of documents. Each document may

contain hundreds of properties. The properties of the documents do not contain distinct values for partitioning. Azure Cosmos DB must scale individual containers in the database to meet the performance needs of the application by spreading the workload evenly across all partitions over time. You need to select a partition key. Which two partition keys can you use? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

  • a concatenation of multiple property values with a random suffix appended
  • a single property value that does not appear frequently in the documents
  • a hash suffix appended to a property value
  • a value containing the collection name
  • a single property value that appears frequently in the documents

Explanation: You can form a partition key by concatenating multiple property values into a single artificial partitionKey property. These keys are referred to as synthetic keys. Another possible strategy to distribute the workload more evenly is to append a random number at the end of the partition key value. When you distribute items in this way, you can perform parallel write operations across partitions. Note: It's the best practice to have a partition key with many distinct values, such as hundreds or thousands. The goal is to distribute your data and workload evenly across the items associated with these partition key values. If such a property doesn’t exist in your data, you can construct a synthetic partition key.

Q91. You are preparing to deploy an ASP.NET Core website to an Azure Web App from a GitHub repository. The website includes static content generated by a script.

You plan to use the Azure Web App continuous deployment feature. You need to run the static generation script before the website starts serving traffic. What are two possible ways to achieve this goal? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point

  • Create a file named .deployment in the root of the repository that calls a script which generates the static content and deploys the website
  • Add a PreBuild target in the websites csproj project file that runs the static content generation script
  • Create a file named run.cmd in the folder /run that calls a script which generates the static content and deploys the website.
  • Add the path to the static content generation tool to WEBSITE_RUN_FROM_PACKAGE setting in the host.json file.

Explanation: A: To customize your deployment, include a .deployment file in the repository root. You just need to add a file to the root of your repository with the name .deployment and the content: [config] command = YOUR COMMAND TO RUN FOR DEPLOYMENT this command can be just running a script (batch file) that has all that is required for your deployment, like copying files from the repository to the web root directory for example. D: In Azure, you can run your functions directly from a deployment package file in your function app. The other option is to deploy your files in the d:\home\site\wwwroot directory of your function app (see A above). To enable your function app to run from a package, you just add a WEBSITE_RUN_FROM_PACKAGE setting to your function app settings. Note: The host.json metadata file contains global configuration options that affect all functions for a function app.

Q93.A company is implementing a publish-subscribe (Pub/Sub) messaging component by using Azure Service Bus. You are developing the first subscription

application. In the Azure portal you see that messages are being sent to the subscription for each topic. You create and initialize a subscription client object by supplying the correct details, but the subscription application is still not consuming the messages. You need to complete the source code of the subscription client What should you do

  • await subscriptionClient.CloseAsync();
  • await subscriptionClient.AddRuleAsync(new RuleDescription(RuleDescription.DefaultRuleName, new TrueFilter()));
  • subscriptionClient.RegisterMessageHandler(ProcessMessagesAsync, messageHandlerOptions);
  • subscriptionClient = new SubscriptionClient(ServiceBusConnectionString, TopicName, SubscriptionName);

Explanation: Using topic client, call RegisterMessageHandler which is used to receive messages continuously from the entity. It registers a message handler and begins a new thread to receive messages. This handler is waited on every time a new message is received by the receiver. subscriptionClient.RegisterMessageHandler(ReceiveMessagesAsync, messageHandlerOptions);
