Question 11 (Mixed Questions)

You are building an ASP.NET Core application.

○
Add the 99 parameter to the ApplicationInsights.config file.
○
From the code of the application, enable adaptive sampling.
○
From the code of the application, add Azure Application Insights telemetry.
○
Add the 5 parameter to the ApplicationInsights.config file.
○
From the code of the application, disable adaptive sampling.

Reference / correct answer:

From the code of the application, enable adaptive sampling.

Add the 5 parameter to the ApplicationInsights.config file.

Sampling is a feature in Azure Application Insights. It is the recommended way to reduce telemetry traffic, data costs, and storage costs, while preserving a statistically correct analysis of application data.

The Application Insights SDK for ASP.NET Core supports both fixed-rate and adaptive sampling. Adaptive sampling is enabled by default.

D: For adaptive sampling: The volume is adjusted automatically to keep within a specified maximum rate of traffic, and is controlled via the setting MaxTelemetryItemsPerSecond. If the application produces a low amount of telemetry, such as when debugging or due to low usage, items won't be dropped by the sampling processor as long as volume is below MaxTelemetryItemsPerSecond.

Note: In ApplicationInsights.config, you can adjust several parameters in the AdaptiveSamplingTelemetryProcessor node. The figures shown are the default values: 5
