In order to identify unused disks that can be deleted from your Azure subscription, which action should you take?

Creating a report from the Optimizer tab in Cloudyn is indeed an effective approach to identify unused disks that can be deleted from your Azure subscription. Cloudyn is a cloud cost management tool that provides visibility into your cloud spending, and its Optimizer feature helps users optimize resource usage by analyzing various aspects of cloud resources, including unused or underutilized resources.

When you open the Optimizer tab and create a report, you can focus specifically on resources that are not being utilized, such as unattached disks. This functionality is crucial for maintaining cost efficiency in your Azure environment, as it allows you to pinpoint resources that are incurring charges without providing any operational benefit.

In contrast, while the Azure portal and Advisor recommendations offer valuable insights and suggestions, they may not provide a straightforward mechanism specifically tailored for identifying unused disks effectively compared to the specialized reporting available in Cloudyn's Optimizer tab. Similarly, generating a Cost Management report in Cloudyn would mainly focus on spending analysis rather than identifying unused resources specifically.
