Microsoft Azure Developer Associate AZ-204 Practice Question

Each synthetic availability test run writes a record to the availabilityResults table and automatically assigns the same value to the operation_Id field of every server-side Request, Dependency, and Exception item generated during that run. By joining or filtering on operation_Id you retrieve only the telemetry that belongs to the failing test executions. Properties such as session_Id, user_Id, or cloud_RoleName are either unrelated to synthetic tests or too general to isolate the specific test run, so they cannot reliably correlate availabilityResults with server-side telemetry.
