An administrator reviews which data sources a diagnostic setting can collect and route to destinations. Which sources are valid diagnostic setting sources? (Select 3 answers)
- APlatform metrics produced automatically by the monitored resource Correct
- BResource logs that are not gathered until a setting enables them Correct
- CActivity log entries describing operations on the subscription Correct
- DPrometheus metrics scraped from a managed Kubernetes cluster
- ECustom metrics pushed straight from an instrumented application
Why A is correct: Correct. Platform metrics produced automatically by the monitored resource is one of the keyed answers. Diagnostic settings collect from three sources: platform metrics and the activity log, both gathered automatically, and resource logs, which are off by default until a setting enables them.
Why B is correct: Correct. Resource logs that are not gathered until a setting enables them is one of the keyed answers. Diagnostic settings collect from three sources: platform metrics and the activity log, both gathered automatically, and resource logs, which are off by default until a setting enables them.
Why C is correct: Correct. Activity log entries describing operations on the subscription is one of the keyed answers. Diagnostic settings collect from three sources: platform metrics and the activity log, both gathered automatically, and resource logs, which are off by default until a setting enables them.
Why D is wrong: Prometheus metrics flow to an Azure Monitor workspace through managed Prometheus, not through a diagnostic setting source.
Why E is wrong: Custom metrics enter via the custom metrics API or Application Insights, not as a diagnostic setting source.
