AI-200 Security And Observability Practice Question
You are setting up monitoring for a custom machine learning scoring script running inside an Azure Container Instance. You want to track custom metrics such as inference prediction confidence scores over time in Application Insights. How should you record these custom metrics in your Python scoring script?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the Application Insights TelemetryClient track_metric() method
Using the `track_metric` method of the Application Insights `TelemetryClient` in Python allows you to record custom numerical metrics and send them to Azure Monitor.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Save the metrics as text files in an Azure Blob Storage account and run hourly KQL queries
Why it's wrong here
Incorrect. Blob storage does not ingest real-time Application Insights metrics natively without custom data ingestion pipelines.
- ✓
Use the Application Insights TelemetryClient track_metric() method
Why this is correct
Correct. TelemetryClient.track_metric allows sending custom metrics directly to Application Insights.
- ✗
Print JSON strings to standard output and rely on Log Analytics automatic table parsing
Why it's wrong here
Incorrect. While Container Instances capture stdout, using the official Application Insights SDK ensures metrics are structured and indexed correctly in custom metrics tables.
- ✗
Update Azure Key Vault secrets with the metric values
Why it's wrong here
Incorrect. Key Vault is for storing secrets and keys, not telemetry metrics.
