AZ-305 · Question 09 · Domain 1.1: Logging and Monitoring

You are designing the monitoring architecture for a globally distributed microservices application hosted on Azure Kubernetes Service (AKS) across three regions.

The development team needs to trace requests end-to-end as they flow through the microservices, identify performance bottlenecks, and view application dependency maps. The solution must minimize custom coding.

Which Azure service should you recommend?

Answer options:

A.

Azure Monitor Network Insights

B.

Application Insights

C.

Log Analytics workspace with custom logs

D.

Azure Data Explorer

How to approach this question

Identify the keywords: 'trace requests end-to-end', 'dependency maps', 'minimize custom coding'. This points directly to an APM tool.

Full Answer

B.Application Insights✓ Correct
Application Insights
Application Insights is Azure's Application Performance Management (APM) service. It automatically discovers application dependencies, generates application maps, and provides distributed tracing to track requests end-to-end across microservices, fulfilling all requirements with minimal to no custom coding (via auto-instrumentation).

Common mistakes

Confusing infrastructure monitoring (Log Analytics/Container Insights) with application performance monitoring (Application Insights).
