Microsoft Azure Administrator (AZ104) Complete Practice Exam 2025

To identify unused disks that can be deleted within an Azure subscription that contains numerous virtual machines, utilizing the Optimizer tab in a tool like Cloudyn is an effective approach. This option offers detailed insights and reporting capabilities specifically tailored to analyze resource utilization.

The Optimizer feature helps to identify resources that are underutilized or idle, including disks that are no longer attached to virtual machines. By generating a report through the Optimizer, you can easily see which disks are unused, enabling informed decisions about resource management and cost optimization.

Other options may not provide the same level of specificity needed for identifying unused disks. For instance, while monitoring account management properties or configuring Azure Advisor recommendations might yield some insights into overall usage or potential optimizations, they do not explicitly focus on identifying unattached or unused disks in the same manner as the Optimizer does. Similarly, creating a Cost Management report can help track spending but may not directly indicate which specific disks could be deleted due to them being unutilized.
