Explanation

Sampling is an effective way to reduce charges and stay within your monthly quota. You can set sampling manually, either in the portal on the Usage and estimated costs page; or in the ASP.NET SDK in the .config file; or in the Java SDK in the ApplicationInsights.xml file, to also reduce the network traffic. Adaptive sampling is the default for the ASP.NET SDK. Adaptive sampling automatically adjusts to the volume of telemetry that your app sends. It operates automatically in the SDK in your web app so that telemetry traffic on the network is reduced. Incorrect Answers: B: You can use the daily volume cap to limit the data collected. To change the daily cap, in the Configure section of your Application Insights resource, in the Usage and estimated costs pane, select Daily Cap. https://docs.microsoft.com/en-us/azure/azure-monitor/app/sampling
