Generate a Monthly Report for Azure Resource Manager (ARM) Resource Deployments

A

Activity logs are kept for 90 days. You can query for any range of dates, as long as the starting date isn't more than 90 days in the past.

Through activity logs, you can determine:

-> what operations were taken on the resources in your subscription

-> who started the operation

-> when the operation occurred

-> the status of the operation

-> the values of other properties that might help you research the operation

The correct answer is A. Azure Activity Log.

Explanation: To generate a monthly report of all the new Azure Resource Manager (ARM) resource deployments in your Azure subscription, you should use Azure Activity Log.

Azure Activity Log is a service in Azure that provides insights into subscription-level events that have occurred in Azure. It tracks any operation that is performed on a resource in Azure and stores it as an activity log. The activity log includes all management activities, such as the creation, deletion, and modification of resources.

To create a monthly report of all new ARM resource deployments, you can use Azure Activity Log to filter for all activities related to resource deployments and then export the data to a reporting tool such as Power BI.

Azure Advisor provides recommendations to optimize your Azure resources and improve their performance, security, and reliability. However, it does not provide information on all new ARM resource deployments in your subscription.

Azure Analysis Services is a fully-managed platform-as-a-service (PaaS) that provides enterprise-grade data models in the cloud. It is not relevant to generating a monthly report of new ARM resource deployments.

Azure Monitor action groups enable you to define a set of actions to execute when an alert is triggered in Azure Monitor. It is not relevant to generating a monthly report of new ARM resource deployments.
