AZ400-Q: Synthetic (availability) tests
Q: A team needs to proactively validate that their web app’s public endpoint responds correctly from multiple geographic locations — even when no real users are online. Which Application Insights feature should they configure?
- A) Live Metrics
- B) Availability (synthetic) tests ✓
- C) Custom event telemetry
- D) Dependency tracking
Answer: B. Availability tests in Application Insights periodically issue synthetic requests to your endpoint from several locations and report whether it responds correctly — proactive availability monitoring without relying on real user traffic. Live Metrics shows real-time telemetry of real users; custom events and dependency tracking analyze behavior/performance, not outbound availability probes.
Why it helps
Availability (synthetic) tests and proactive alerting are core “synthetic testing & alerting” AZ-400 objectives.
