You are building an ASP.NET Core application. You plan to create an application utilization baseline by capturing telemetry data. You need to add code to the application to capture the telemetry data. The solution must minimize the costs of storing the telemetry data. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point
Answer: CE
C & E Disable Adaptive Sampling and use Fixed Rate Sampling instead: "Fixed-rate sampling reduces the volume of telemetry sent from both your ASP.NET or ASP.NET Core or Java server and from your users' browsers. You set the rate. The client and server will synchronize their sampling so that, in Search, you can navigate between related page views and requests." https://docs.microsoft.com/en-us/azure/azure-monitor/app/sampling

You have an Azure DevOps organization named Contoso and an Azure subscription. The subscription contains an Azure virtual machine scale set named VMSS1 and an Azure Standard Load Balancer named LB1. LB1 distributes incoming requests across VMSS1 instances. You use Azure DevOps to build a web app named App1 and deploy App1 to VMSS1. App1 is accessible via HTTPS only and configured to require mutual authentication by using a client certificate. You need to recommend a solution for implementing a health check of App1. The solution must meet the following requirements: ✑ Identify whether individual instances of VMSS1 are eligible for an upgrade operation. ✑ Minimize administrative effort. What should you include in the recommendation?
Answer: D
D. the Application Health extension When to use the Application Health extension The Application Health Extension is deployed inside a Virtual Machine Scale Set instance and reports on application health from inside the scale set instance. The extension probes on a local application endpoint and will update the health status based on TCP/HTTP(S) responses received from the application. This health status is used by Azure to initiate repairs on unhealthy instances and to determine if an instance is eligible for upgrade operations. The extension reports health from within a VM and can be used in situations where an external probe such as the Azure Load Balancer health probes can’t be used. https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-health-extension?tabs=rest-api

HOTSPOT - You have an application named App1 that has a custom domain of app.contoso.com. You create a test in Azure Application Insights as shown in the following exhibit.
Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic. NOTE: Each correct selection is worth one point. Hot Area:
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
Box 1: every five minutes at a random location Test frequency: Sets how often the test is run from each test location. With a default frequency of five minutes and five test locations, your site is tested on average every minute. Box 2: Parse dependent requests: Test requests images, scripts, style files, and other files that are part of the web page under test. The recorded response time includes the time taken to get these files. The test fails if any of these resources cannot be successfully downloaded within the timeout for the whole test.

You have a build pipeline in Azure Pipelines that occasionally fails. You discover that a test measuring the response time of an API endpoint causes the failures. You need to prevent the build pipeline from failing due to the test. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
Answer: BD
BD is the answer. https://learn.microsoft.com/en-us/azure/devops/pipelines/test/flaky-test-management?view=azure-devops#flaky-test-management-and-reporting On the Test management page under Flaky test options, you can set options for how flaky tests are included in the Test Summary report. Flaky test data for both passed and failed test is available in Test results. The Flaky tag helps you identify flaky tests. By default, flaky tests are included in the Test Summary. However, if you want to ensure flaky test failures don't fail your pipeline, you can choose to not include them in your test summary and suppress the test failure. This option ensures flaky tests (both passed and failed) are removed from the pass percentage and shown in Tests not reported.

Your company hosts a web application in Azure. The company uses Azure Pipelines for the build and release management of the application. Stakeholders report that the past few releases have negatively affected system performance. You configure alerts in Azure Monitor. You need to ensure that new releases are only deployed to production if the releases meet defined performance baseline criteria in the staging environment first. What should you use to prevent the deployment of releases that fall to meet the performance baseline?
Answer: C
C is the answer. https://learn.microsoft.com/en-us/azure/devops/pipelines/release/approvals/gates?view=azure-devops Gates allow automatic collection of health signals from external services and then promote the release when all the signals are successful or stop the deployment on timeout. Typically, gates are used in connection with incident management, problem management, change management, monitoring, and external approval systems.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. 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 manage a project in Azure DevOps. You need to prevent the configuration of the project from changing over time. Solution: Perform a Subscription Health scan when packages are created. Does this meet the goal?
Answer: B
“Secure DevOps Kit for Azure (AzSK) is being sunset”. Some of the tools that will phase out seem to be ARM Checker, DevOps Kit CICD Extension and AAD Scanner (AzSK.AAD). The tool that will replace them is Azure Tenant Security Solution (AzTS). Based on the original note, ADO Scanner - used to secure your Azure DevOps set-up will continue to be updated. If you are looking for ARM template validation and verification only you can also check the following approaches: Test-AzDeployment What-if operation Validate templates So, if you have a dependency on Secure DevOps Kit for Azure (AzSK) make sure the update, there are options available. DevSecOps in Azure Reference architecture is available here. https://github.com/azsk/AzTS-docs https://learn.microsoft.com/en-us/azure/architecture/solution-ideas/articles/devsecops-in-azure

Your company uses the following resources: ✑ Windows Server 2019 container images hosted in an Azure Container Registry. ✑ Azure virtual machines that run the latest version of Ubuntu ✑ An Azure Log Analytics workspace ✑ Azure Active Directory (Azure AD) ✑ An Azure key vault For which two resources can you receive vulnerability assessments in Azure Security Center? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
Answer: CE
Answer: B & C I know, it's weird to agree with the solution provided by exam topics. But why do I agree? 1) create a Keyvault and a VM 2) go to each resource, and search for "security" in the left pane 3) view the security recommendations. Also, note the blue banner on top stating: "Visit Security Center to manage security across your virtual networks, data, apps, and more"

You use Azure Pipelines to manage build pipelines, GitHub to store source code, and Dependabot to manage dependencies. You have an app named App1. Dependabot detects a dependency in App1 that requires an update. What should you do first to apply the update?
Answer: B
If a dependency update is found, a new Pull Request is created with the upgraded dependency and an email notification is sent. All we need to do is review the Pull Request, ensure all of the tests passed successfully, and we can confidently approve and merge this update.

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 have an Azure DevOps organization named Contoso and an Azure subscription. The subscription contains an Azure virtual machine scale set named VMSS1 that is configured for autoscaling. You have a project in Azure DevOps named Project1. Project1 is used to build a web app named App1 and deploy App1 to VMSS1. You need to ensure that an email alert is generated whenever VMSS1 scales in or out. Solution: From Azure Monitor, configure the autoscale settings. Does this meet the goal?
Answer: B
I think you don't need an action group, you only need to check the box for "Email administrators", "Email co-administrator", or add email on the text field based on this https://www.trendmicro.com/cloudoneconformity/knowledge-base/azure/VirtualMachines/enable-autoscale-notifications.html
