Which of the following is a type of alert that can be created using the Azure command line interface (CLI)?

The type of alert that can be created using the Azure command line interface (CLI) is related to metrics. Metric alerts are designed to monitor specific metrics within Azure resources and notify users when those metrics cross specified thresholds.

Metric alerts leverage the ability to monitor the performance and health of applications and resources in real-time. When you set up a metric alert, you can define conditions based on various metrics such as CPU usage, memory usage, disk I/O, and more, which helps ensure that you can respond to potential issues effectively. When a defined metric condition is met, you receive notifications so you can take proactive measures.

While log alerts, event alerts, and historical data monitoring may be part of broader monitoring solutions in Azure, the CLI primarily supports the creation and management of metric alerts in a straightforward manner. Therefore, focusing on metrics is crucial for maintaining the reliability and performance of Azure deployments.
