AZ-204 Application Insights Practice Question
A developer needs to run a Kusto query against application request data to identify 95th percentile latency by operation. Where should the query be run? The architecture review board prefers a managed Azure-native control.
⚠ Common exam trap
Watch out — candidates often confuse Azure Resource Graph with Log Analytics, thinking it can query telemetry data, but Resource Graph only returns resource inventory and configuration state, not performance metrics.
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
✓
Logs in Application Insights or the associated Log Analytics workspace
Application Insights stores telemetry data, including request latency, in a Log Analytics workspace. Kusto queries against this data can compute percentiles (e.g., 95th) using the `percentile()` function. This is the correct location because the architecture review board prefers a managed Azure-native control, and Log Analytics is the native Azure monitoring service for running such queries.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Logs in Application Insights or the associated Log Analytics workspace
Why this is correct
Application Insights stores telemetry that can be queried with KQL in Logs.
- ✗
Microsoft Entra audit logs
Why it's wrong here
Entra audit logs track identity events, not application performance telemetry.
- ✗
Azure Key Vault diagnostic settings
Why it's wrong here
Key Vault logs do not contain application request latency.
- ✗
Azure Resource Graph only
Why it's wrong here
Resource Graph queries Azure resource metadata, not application request telemetry.
