An operations team wants an alert within minutes when a web app starts throwing unhandled exceptions after a release. Which approach gives automatic detection and notification?
Show answer and explanation
Answer: A
Application Insights collects exception telemetry in near real time. Smart Detection analyses that telemetry and flags unusual increases in failures and slow responses without manually configured thresholds. Metric alert rules on exception counts or failed request rates can notify the on-call team as soon as a threshold is crossed. The other options monitor storage transactions, sprint progress, or code changes, none of which reveal whether application code is failing.
Why the other options are wrong
- B. Storage Analytics records blob and queue transactions. It does not capture unhandled exceptions raised inside the web application's code.
- C. Velocity dashboards summarise completed work per sprint. They do not reflect runtime errors happening in production.
- D. Commit notifications report code changes to developers. They say nothing about whether the deployed application is currently failing.
