Correct Answer: A, BTo address the need to increase the logging level when the web app exceeds normal usage patterns while minimizing administrative overhead, two key resources are essential. First, an Azure Monitor alert with a dynamic threshold is crucial, as it leverages advanced machine learning to learn historical usage patterns and detect anomalies, ensuring alerts are only triggered when necessary. This helps maintain an efficient monitoring system without constant manual adjustments. Secondly, an Azure Automation runbook is needed to automate the increase in logging levels when the alert is triggered. This allows for a swift, hands-off response to detected anomalies, keeping administrative overhead to a minimum.
