Exam AZ-204 topic 5 question 39 discussion

B E F B. Enable Application Insights site extensions: Application Insights provides end-to-end insights into the web app's performance and usage. Enabling the Application Insights site extension allows you to collect telemetry data, including call stack traces, to help identify performance issues in the code. E. Enable the Always On setting for the app service: Enabling the Always On setting ensures that the web app is always running, even when there is no traffic. This reduces the impact of cold starts and improves the web app's response time. F. Enable Snapshot debugger: Enabling Snapshot debugger allows you to capture the complete call stack and local variables for an exception that occurred in the web app. This helps to identify performance issues and diagnose issues in the code.

B, D, E Gotta enable App Insights. Always On can solve the performance issues. Profiler can help find performance issues. You can eliminate Premium upgrade because it says minimize costs, snapshot debugger is for debugging exceptions and has nothing to do with performance issues, restarting app impacts users and it says minimize impact.

B. Enable Application Insights site extensions. D. Enable Profiler. E. Enable the Always On setting for the app service.

The given answer is correct: D, E, F. Restarting apps will disrupt users and does not solve the problem. Application Insights site extensions are deprecated and now come pre-installed on an App Service. Premium is not necessary for instrumentation (although it would help with performance). Enabling the Profiler lets us view performance, for which Always On is necessary. Snapshot debugging lets us view the call stack. Therefore D, E, F.

- E : Enable the Always On setting does not add direct value to capture in telemetry and solve performance problems . - F : Enable Snapshot debugger capture snapshots . So correct asnwer B , D , F

BDF - 「You must minimize cost and impact to users on the web app.」 E. Enable the Always On setting for the app service. Enhances user experience, ensuring the web app does not enter a sleep or stop state due to inactivity - Yes May increase the cost of the web app since it will always remain active and not enter a sleep state - No F. Enable Snapshot debugger. Will not impact users - Yes Will not increase the cost of the web app - Yes

BDE F Snapshot debugger is to capture information in case of a failure. This is only about performance issues.

B: There is no need to discuss. D: from msLearn, > With Application Insights Profiler, you can capture, identify, and view performance traces for your application running in Azure, regardless of the scenario. The Profiler trace process occurs automatically, at scale, and doesn't negatively affect your users. https://learn.microsoft.com/en-US/azure/azure-monitor/snapshot-debugger/snapshot-debugger E: If you want to use Application Insights Profiler, you have to set Always on for App Services. https://learn.microsoft.com/en-US/azure/azure-monitor/profiler/profiler#verify-the-always-on-setting-is-enabled F: This is not the answer. from mslearn, > with Snapshot Debugger, you can automatically collect a debug snapshot when an EXCEPTION OCCURS in your live .NET application. https://learn.microsoft.com/en-US/azure/azure-monitor/snapshot-debugger/snapshot-debugger

Enable Application Insights site extensions (B): To collect comprehensive telemetry and performance data. Enable Profiler (D): To capture detailed performance traces and call stacks for slow requests. Enable Snapshot debugger (F): To take snapshots of the app in production, capturing the state and call stack at specific points without heavily impacting users.

You need to activate Profiler (D) and to do this, as prerequisites, Application Insights (B) and AlwaysOn (E) must be enabled

The alwayson option does not help us gathering the needed data, so should be BDF

Oh goody, it's one of those questions where no one can agree on a definite answer. Greaaaat.

For me: - Enable Application Insights site extensions - Enable Profiler - Enable Snapshot debugger

BDE is the correct answer. Profiler capture data automatically without negatively affecting users.

Always On is available from Standard tier

B. Enable Application Insights site extensions. This will allow you to collect telemetry from your web app, including performance metrics, failed requests, and dependencies. D. Enable Profiler. The Application Insights Profiler will help you identify performance issues in your app's code by capturing telemetry about the app's slowest operations. F. Enable Snapshot debugger. The Snapshot Debugger takes snapshots of your in-production apps when exceptions occur, allowing you to see exactly what went wrong without affecting traffic of your production application.

D) Enable profiler With Application Insights Profiler, you can capture and view performance traces for your application in all these dynamic situations. The process occurs automatically at scale and doesn't negatively affect your users. Profiler captures the following information so that you can easily identify performance issues while your app is running in Azure (https://learn.microsoft.com/en-us/azure/azure-monitor/profiler/profiler-overview) E)enable always on (to enable profiler -> https://learn.microsoft.com/en-us/azure/azure-monitor/profiler/profiler ) F)Snapshot debugger - to collect call stacks for your application - https://learn.microsoft.com/en-us/azure/azure-monitor/snapshot-debugger/media/snapshot-debugger/enablement-ui.png
