AZ-204 Exam - Question 328

Question

You develop an ASP. Net Core application by integrating the Application Insights SDK into your solution.

The application sends a very high rate of telemetry in a short time interval. You observe a reduced number of events, traces, and metrics being recorded and increased error rates for telemetry ingestion.

You need to reduce telemetry traffic, data costs, and storage costs while preserving a statistically correct analysis of application telemetry data. Your solution must ensure that you will be able to correlate HTTP request and response data.

What should you do?

The issue in the scenario describes high telemetry ingestion leading to data loss and increased error rates. To reduce telemetry traffic, data costs, and storage costs while maintaining statistical accuracy and correlation of HTTP requests and responses, the best approach is to use fixed-rate sampling. Unlike adaptive sampling, which dynamically adjusts based on load, fixed-rate sampling provides predictable control over telemetry volume.

Fixed-rate sampling is better in such scenarios because it preserves the full correlation chain within sampled data and gives you consistent behavior across distributed components.
