   You build an iOS app. You receive crash reports from Crashlytics. You need to capture the following data: ✑ Crash-free users ✑ Custom events ✑ Breadcrumbs What should you do?

   • AConfigure the xcworkspace file in the project
   • BAdd the GoogleAnalytics pod to the app.
   • CConfigure the Crashlytics pod in the app.
   • DImport the Firebase module to UIApplicationDelegate.

   Show answer

   Answer: D

   Explanation

   If you're not seeing crash-free users, breadcrumb logs, and/or velocity alerts, we recommend checking your app's configuration for Google Analytics. [...] In addition to the Firebase Crashlytics SDK, make sure that you've added the Firebase SDK for Google Analytics to your app (iOS+ | Android). (https://firebase.google.com/docs/crashlytics/troubleshooting?platform=ios#missing-analytics-related-features) To configure the Firebase Crashlytics SDK: [...]Next, configure the Firebase module [...] Import the Firebase module in your App struct or UIApplicationDelegate (https://firebase.google.com/docs/crashlytics/get-started?platform=ios#add-sdk) Given answer D is correct.

   You have multiple teams that work on multiple projects in Azure DevOps. You need to plan and manage the consumers and producers for each project. The solution must provide an overview of all the projects. What should you do?

   • AAdd a Predecessor or Successor link to the feature or user story for the items of each project.
   • BAdd a Parent or Child link to the feature or user story for the items of each project.
   • CInstall the Dependency Tracker extension and create dependencies for each project.
   • DCreate a custom query to show the consumers and producers and add a widget to a dashboard.

   Show answer

   Answer: C

   Explanation

   You use the Dependency Tracker to plan dependencies at the beginning of an iteration or release, and to track the status during development. For any given dependency, there are two parties involved: Consumer: Feature team who has a need and starts a request for work Producer: Feature team who makes a commitment to deliver work https://learn.microsoft.com/en-us/azure/devops/boards/extensions/dependency-tracker?view=azure-devops

   DRAG DROP - You have a GitHub repository that contains the source code for an app named App1. You need to create process documentation for App1. The solution must include a diagram that displays the relationships between the phases of App1 as shown in the following exhibit.

   

   How should you complete the markdown code? To answer, drag the appropriate values to the correct targets. Each value 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.

   

   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

   Explanation

   Look for the word "state" in the syntax. This is clearly a state diagram. "A state diagram is a type of diagram used in computer science and related fields to describe the behavior of systems. State diagrams require that the system described is composed of a finite number of states; sometimes, this is indeed the case, while at other times this is a reasonable abstraction." "A Sequence diagram is an interaction diagram that shows how processes operate with one another and in what order."

   HOTSPOT - You have an Azure web app named webapp1 that uses the .NET Core runtime stack. You have an Azure Application Insights resource named AppInsights1 that collects telemetry data generated by webapp1. You plan to deploy webapp1 by using an Azure DevOps pipeline. You need to modify the sampling rate of the telemetry data processed by AppInsights1 without having to redeploy webapp1 after each modification. What should you do? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

   

   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.

   Show the answer figure

   Answer: See figure below

   Explanation

   1. Disable adaptive sampling 2. Modify usage and estimated costs settings https://learn.microsoft.com/en-us/azure/azure-monitor/app/sampling#types-of-sampling Ingestion sampling happens at the Application Insights service endpoint. It discards some of the telemetry that arrives from your app, at a sampling rate that you set. It doesn't reduce telemetry traffic sent from your app, but helps you keep within your monthly quota. The main advantage of ingestion sampling is that you can set the sampling rate without redeploying your app. Ingestion sampling works uniformly for all servers and clients, but it doesn't apply when any other types of sampling are in operation. https://learn.microsoft.com/en-us/azure/azure-monitor/app/sampling#ingestion-sampling Ingestion sampling doesn't operate while adaptive or fixed-rate sampling is in operation. Adaptive sampling is enabled by default when the ASP.NET SDK or the ASP.NET Core SDK is being used, or when Application Insights is enabled in Azure App Service or by using Application Insights Agent.

   Select 2

   Your company has multiple microservices-based apps that use the following tracing libraries: • OpenTelemetry • OpenCensus • OpenTracing • Honeycomb • Jaeger The company purchases an Azure subscription and implements Application Insights in Azure Monitor. You plan to centralize distributed tracing for the apps. You need to identify which libraries can integrate directly with Application Insights. Which two libraries should you identify? Each correct answer presents a complete solution. NOTE: Each correct solution is worth one point.

   • AHoneycomb
   • BOpenTracing
   • CJaeger
   • DOpenTelemtry
   • EOpenCensus

   Show answer

   Answer: DE

   Explanation

   Application Insights now supports distributed tracing through OpenTelemetry. OpenTelemetry provides a vendor-neutral instrumentation to send traces, metrics, and logs to Application Insights. Initially, the OpenTelemetry community took on distributed tracing. In addition to the Application Insights SDKs, Application Insights also supports distributed tracing through OpenCensus. OpenCensus is an open-source, vendor-agnostic, single distribution of libraries to provide metrics collection and distributed tracing for services. https://learn.microsoft.com/en-us/azure/azure-monitor/app/distributed-tracing

6. Question 86 · 540 in bank

   You have an Azure web app named webapp1 that uses the .NET Core runtime stack. You have an Azure Application Insights resource named AppInsights1. Webapp1 sends telemetry data to AppInsights1. You need to ensure that webapp1 sends the telemetry data at a fixed sampling rate. What should you do?

   • AFrom the code repository of webapp1, modify the ApplicationInsights.config file.
   • BFrom the code repository of webapp1, modify the Startup.cs file.
   • CFrom AppInsights1, modify the Usage and estimated costs settings.
   • DFrom AppInsights1, configure the Continuous export settings.

   Show answer

   Answer: B

   Explanation

   Right now 36% voted A and that is completely wrong. NET Core does not have applicationinsights.config, as it says here: https://learn.microsoft.com/en-us/azure/azure-monitor/app/configuration-with-applicationinsights-config "The ApplicationInsights.config and .xml instructions don't apply to the .NET Core SDK. To configure .NET Core applications, follow the instructions in Application Insights for ASP.NET Core applications." The answer is either B or as Net Core 6, Program.cs

   Answer: See figure below

   Explanation

   timestamp is for Logs and continent for Events (App 1 manages events in multiple locations) So must be: Logs | where Timestamp > ago(1d) | join ( Events | where continent == 'Europe' ) on RequestId https://hybriddbablog.com/2022/03/31/kql-series-understanding-kql-queries-part-2/

   Explanation

   from the last 24 hours: TimeGenerated > ago(24h) compare the hourly CPU usage: bin(TimeGenerated, 1h) must include a graph that has threshold line at 75 percent: extend Threshold = 75 But you need to use "render timechart" after, to generate the graph with the threshold line with static value 75.
