Developing Solutions for Microsoft Azure practice questions

1. Question 1 of 25

   Your company's Azure subscription includes an Azure Log Analytics workspace. Your company has a hundred on-premises servers that run either Windows Server 2012 R2 or Windows Server 2016, and is linked to the Azure Log Analytics workspace. The Azure Log Analytics workspace is set up to gather performance counters associated with security from these linked servers. You must configure alerts based on the information gathered by the Azure Log Analytics workspace. You have to make sure that alert rules allow for dimensions, and that alert creation time should be kept to a minimum. Furthermore, a single alert notification must be created when the alert is created and when the alert is resolved. You need to make use of the necessary signal type when creating the alert rules. Which of the following is the option you should use?

   • AThe Activity log signal type.
   • BThe Application Log signal type.
   • CThe Metric signal type.
   • DThe Audit Log signal type.

      The solution mentioned, which is configuring Client cert gateway credentials for the HTTP(s) endpoint, does not meet the goal of configuring back-end authentication for the API Management service instance. Client certificate authentication is used for authenticating clients accessing the API Management service, not for authenticating the back-end service itself. To configure back-end authentication for the API Management service instance hosted in an Azure App Service, you have several options, such as: API key authentication: Generate an API key and configure it in the API Management service to authenticate requests sent to the back-end service. OAuth 2.0 authentication: Configure OAuth 2.0 authentication between the API Management service and the back-end service, allowing clients to authenticate using OAuth 2.0 tokens. Certificate-based authentication: If your back-end service supports certificate-based authentication, you can configure the API Management service to authenticate requests using client certificates. Therefore, the correct answer is: B. No

      Client Cert Gateway Credentials: Can be used with both HTTP endpoints and Azure resources if both are configured to handle and validate client certificates. Provides strong security and is suitable for high-security scenarios, but involves a more complex setup. Basic Gateway Credentials: Suitable for HTTP endpoints that support Basic Authentication but not suitable for Azure resources like Azure App Service. Basic Authentication is less secure and generally not used for Azure resources, which typically require Azure AD, OAuth tokens, or managed identities for authentication. For a public-facing API, client certificate authentication is generally preferred if both APIM and the backend API are properly configured to use and validate client certificates. Basic Authentication is simpler but less secure and not suitable for most Azure resources. Azure App Service does not support Basic Authentication (Basic gateway credentials) for securing access to the service itself. For securing Azure App Service, you should use Azure AD, OAuth 2.0, or other more secure authentication methods

In Visual Studio Code, you can open and edit the workflow definition for an already deployed logic app in Azure. ..." In this other link, https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-author-definitions, you can read: 1.- Sign in to the Azure portal. 2.- From the left menu, choose All services. In the search box, find "logic apps", and then from the results, select your logic app. 3.- On your logic app's menu, under Development Tools, select Logic App Code View. 4.- The Code View editor opens and shows your workflow definition in JSON format. So, I think that the correct answer is B.

      The correct answer to this question is D, the Logic Apps Designer. The Logic Apps Designer is a visual, low-code interface that allows developers to create, edit, and manage Logic Apps without having to write code. It provides a drag-and-drop interface that enables developers to add and configure connectors, actions, and triggers to create a workflow. The Logic App Code View is an advanced feature that enables developers to edit the underlying code of a Logic App, but it is not required for basic editing of workflows. The Enterprise Integration Pack (EIP) is a set of connectors that provides additional capabilities for connecting to on-premises systems and services, but it is not required for editing workflows. The API Connections are used to securely connect to APIs and services, but they do not provide editing capabilities for Logic App workflows.

      Azure WebJobs is not a service, you'll host the WebJobs SDK functions in Azure WebApps. With Webjobs you program code in your webapp and you'll be able to execute 'kind of Azure functions' inside your Web App. It is automatically deployed with the deployment of the web app. WebJobs is the predecessor of Azure functions.

      B. WebJobs WebJobs is the most appropriate service for this scenario because: The question specifically mentions using the WebJobs SDK to design a triggered App Service background task. WebJobs is a feature of Azure App Service that enables you to run background tasks in the same instance as a web app. The WebJobs SDK is designed specifically for running background tasks in Azure App Service, and it provides support for triggered jobs that can be automatically invoked when new data is received in a queue. WebJobs can be configured to run continuously and respond to events, such as messages being added to a queue. The scenario describes a task that automatically invokes a function when new data is received in a queue, which aligns perfectly with the capabilities of WebJobs and the WebJobs SDK. While Azure Functions (option D) could also potentially be used for this scenario, the question explicitly mentions using the WebJobs SDK, making WebJobs the most appropriate choice for this specific use case.

      WebJob is not a service, but other options are not correct. The service is mentioned in the question: "WebJobs SDK to design a triggered App Service background task". Due to we use App Service and WebJobs is the only feature of this service in the options list, then I select B.

      "Update domains indicate groups of virtual machines and underlying physical hardware that can be rebooted at the same time. When more than five virtual machines are configured within a single availability set with five update domains, the sixth virtual machine is placed into the same update domain as the first virtual machine, the seventh in the same update domain as the second virtual machine, and so on." Given that we want to maximize the number of VMs available at all times, we want to maximize the number of update domains – e.g. a single update domain would basically mean no redundancy at all. Having said that, there is a constraint on the maximum number of update domains: "Each availability set can be configured with up to three fault domains and twenty update domains."

      To ensure that the maximum number of virtual machines remain accessible during fabric updates or maintenance, you need to configure the platformUpdateDomainCount property to a value that is equal to or greater than the number of virtual machines you want to deploy. The platformUpdateDomainCount property specifies the number of update domains used by the availability set. An update domain is a group of virtual machines and underlying physical hardware that can be updated or rebooted at the same time. By spreading virtual machines across multiple update domains, you can ensure that only a subset of virtual machines are impacted by any given update or maintenance event. Therefore, to deploy as many virtual machines as possible while ensuring high availability, you should configure the platformUpdateDomainCount property to a value of 40, which is the maximum allowed value for this property. This ensures that the virtual machines are spread across 40 update domains, providing maximum redundancy and availability during fabric updates and maintenance. So the answer is D. 40.

It provides a secure and reliable connection between on-premises data sources and cloud-based services. However, in the context of migrating MongoDB to Azure Cosmos DB, the Data Management Gateway tool is not relevant. Instead, you should use one of the available migration tools such as the Azure Database Migration Service or the mongoimport/mongodump utilities to migrate your data.

   Explanation

   Shipping Logic app: Secure resources to the corporate VNet and use dedicated storage resources with a fixed costing model. For scenarios where your logic apps and integration accounts need access to an Azure virtual network, create an integration service environment (ISE). An ISE is a dedicated environment that uses dedicated storage and other resources that are kept separate from the "global" multi-tenant Logic Apps service. This separation also reduces any impact that other Azure tenants might have on your apps' performance. An ISE also provides you with your own static IP addresses. These IP addresses are separate from the static IP addresses that are shared by the logic apps in the public, multi-tenant service.

      Correct answer is A: App Service Environments are appropriate for application workloads that require: High scale. Isolation and secure network access. High memory utilization. High requests per second (RPS). You can create multiple App Service Environments in a single Azure region or across multiple Azure regions. This flexibility makes an App Service Environment ideal for horizontally scaling stateless applications with a high RPS requirement. https://learn.microsoft.com/en-us/azure/app-service/environment/overview There is nothing about security, apart from that ISE is "fully isolated": https://azure.microsoft.com/en-us/updates/integration-service-environments-ise-are-now-generally-available/?cdn=disable

      The answer options are obviously outdated. Instead of ISE, it should be Standard logic apps which is the service that replaced ISE but added more features. You can also connect to private vnets. If Standard logic apps is not an option, the most correct one is vnet service endpoint but it doesn't satisfy the fixed pricing model. https://learn.microsoft.com/en-us/azure/logic-apps/connect-virtual-network-vnet-isolated-environment-overview

       Streaming Logs While developing an application, you often want to see what's being written to the logs in near real time when running in Azure. There are two ways to view a stream of the log data being generated by your function executions. Built-in log streaming: the App Service platform lets you view a stream of your application log files. This stream is equivalent to the output seen when you debug your functions during local development and when you use the Test tab in the portal. All log-based information is displayed. For more information, see Stream logs. This streaming method supports only a single instance, and can't be used with an app running on Linux in a Consumption plan.

No SLA. 2) Basic Service Plan - lower traffic requirements and do not need advanced auto scale and traffic management features. . Built-in network load balancing support automatically distributes traffic across instances. 3) Standard Service Plan - For running production workloads. Built-in network load balancing support automatically distributes traffic across instances. The Standard plan includes auto scale that can automatically adjust the number of virtual machine instances running to match your traffic needs. 4) Premium v2 Service Plan - Faster processors, SSD storage and double memory-to-core ratio compared to Standard. 5) Premium v3 Service Plan - faster processors, Hyper-V virtualisation and support for VNet connectivity. 6) Isolated Service Plan - mission critical workloads, which are required to run in a virtual network.

       I think the question C vs D is not really about price, because the same VMs you would run with App Service would cost you much less with a scale set. Even with Load Balancer and storage it's cheaper (at least 30$/month per instance). However the answer says: 1. Deploy the website to a virtual machine 2. Configure a Scale Set to increase the virtual machine instance count when the CPU load is high. Which is in fact incorrect, because you deploy the app to the scale set - you can't add an existing VM with data to a scale set or configure it to add VM instances. You deploy a "VM scale set" as a entire entity. You can attach a custom VHD there, but it's not stated in the answer.

Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. 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: Move photo processing to an Azure Function triggered from the blob upload. Does the solution meet the goal?

    Explanation

    The answer is correct, but it should have also mentioned that the function app must not be on a consumption plan. because in that case, it might take up to 10 minutes to process the event.

       A Blob Trigger is not a recommended approach due to it's lower reliability. Quoting the docs: "Polling works as a hybrid between inspecting logs and running periodic container scans. Blobs are scanned in groups of 10,000 at a time with a continuation token used between intervals. If your function app is on the Consumption plan, there can be up to a 10-minute delay in processing new blobs if a function app has gone idle." "There's no guarantee that all events are captured. Under some conditions, logs may be missed." The latency can be handled by putting the function on a Dedicated plan with Always On setting, but due to the lack of reliability, a recommended approach is to switch to Event Grid based trigger: https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-trigger?tabs=in-process%2Cextensionv5&pivots=programming-language-csharp#polling-and-latency

       It's tricky, but the answer is YES. The scenario is not similar, since here they don't say it is triggered by a BlobTrigger, but triggered from the blob upload, which could also be an EventGridTrigger. The question mentioning that is runs on v2 tells me that YES is the right answer.

       Should be NO for two reasons: 1) The Azure Blob storage trigger requires a general-purpose storage account. Storage V2 accounts with hierarchical namespaces are also supported. The question has no mention about hierarchical namespaces. 2) For blobs, polling works on a "best effort" basis. There's no guarantee that all events are captured. If you require faster or more reliable blob processing, consider creating a queue message when you create the blob.

18. Question 18 of 25

    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 the Function App is triggered. You need to configure the Function App. What should you do?

    • AUse an App Service plan. Configure the Function App to use an Azure Blob Storage input trigger.
    • BUse a Consumption plan. Configure the Function App to use an Azure Blob Storage trigger.
    • CUse a Consumption plan. Configure the Function App to use a Timer trigger.
    • DUse an App Service plan. Configure the Function App to use an Azure Blob Storage trigger.

    Explanation

    The answer is D. Use an App Service plan. Configure the Function App to use an Azure Blob Storage trigger. Consumption plan can cause a 10-min delay in processing new blobs if a function app has gone idle. To avoid this latency, you can switch to an App Service plan with Always On enabled. https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-trigger?tabs=csharp

       Correct Answer: D We definitely need an Azure Blob Storage trigger. There is not Azure Blob Storage input trigger. Input bindings allow you to read blob storage data as input to an Azure Function, not trigger. With Consumption plan, you could have cold start, and the question say "must be processed as quickly as possible". If your Function App is on the Consumption plan, there can be up to a 10-minute delay in processing new blobs if a function app has gone idle. So, we need an App Service Plan.

Microsoft says: ".....Use Event Grid instead of the Blob storage trigger for the following scenarios:" 1-Blob-only storage accounts: Blob-only storage accounts are supported for blob input and output bindings but not for blob triggers. 2-High-scale: High scale can be loosely defined as containers that have more than 100,000 blobs in them or storage accounts that have more than 100 blob updates per second. 3-Minimizing latency: If your function app is on the Consumption plan, there can be up to a ##10-minute delay in processing new blobs## if a function app has gone idle. To avoid this latency, you can switch to an App Service plan with Always On enabled. You can also use an Event Grid trigger with your Blob storage account.

       I've experienced this in one project I was participating in. If the amount of blobs becomes high enough (like 50k+) blob trigger becomes completely unreliable. It may not trigger at all or delay can be greater than 1 hour. It had nothing to do with Consumption Plan. Switching to Event Grid resolved that issue. So blob trigger DOESN'T guarantee processing within 1 minute, so anwer (B) is correct

    Explanation

    I had the exam last Friday and I notice that they change one sentence in case study from: Application Insights must always contain all log messages. to: Application Insights currently contain all log messages. So I chosen C. Implement Application Insights Sampling.

       The case states "The processor also has TraceWriter logging enabled. Application Insights must always contain all log messages." For this reason B isn't an option, and neither is A or D. These would all change what log messages are sent to AI, which isn't according to reqs. So this leaves C. Sampling just groups messages together with a count, causing less traffic to AI but the same results.

       A. Create an Application Insights Telemetry Filter > A filter can be created by either implementing ITelemetryProcessor or by implementing ITelemetryInitializer. However MS recommends to use sampling https://docs.microsoft.com/en-us/azure/azure-monitor/app/api-filtering-sampling#filtering B. Change the minimum log level in the host.json file for the function > Can be ruled out because req. says app insights must always contain all log messages C. Implement Application Insights Sampling > Is the recommended way to reduce telemetry traffic, data costs and storage costs > https://docs.microsoft.com/en-us/azure/azure-monitor/app/sampling > https://blog.ramondeklein.nl/2017/05/05/filtering-application-insights/ D. Set a LogCategoryFilter during startup > No idea what that is, but feels like pointint in the same direction as the B does

       The answer is "B". From the problem description: "Developers report that the number of log messages in the trace output for the processor is too high" The keywords are "too high". The answer is to change the minimum logging level.

24. Question 24 of 25

    You need to deploy the CheckUserContent Azure Function. The solution must meet the security and cost requirements. Which hosting model should you use?

    • APremium plan
    • BApp Service plan
    • CConsumption plan

    Correct answer: B

    • B100%

    Explanation

    A is correct! I guess the guy gives the answer confused with which one is cheaper. Premium is cheaper than app service place. It can auto scale, warm starting and with VNET integration. In addition, it can run custom container as well, just the same as app service plan.

       I believed the answer is correct. https://docs.microsoft.com/en-us/azure/azure-functions/dedicated-plan "You pay for function apps in an App Service Plan as you would for other App Service resources. This differs from Azure Functions Consumption plan or Premium plan hosting..." So.. ASE can be made available on the App service plan that hosting the function
