You have an Azure subscription that contains an Azure Storage account.
You plan to implement changes to a data storage solution to meet regulatory and compliance standards.
Every day, Azure needs to identify and delete blobs that were NOT modified during the last 100 days.
Solution: You apply an expired tag to the blobs in the storage account.

A. B.B
Instead apply an Azure Blob storage lifecycle policy.
https://docs.microsoft.com/en-us/azure/storage/blobs/storage-lifecycle-management-concepts?tabs=azure-portalThe proposed solution to apply an expired tag to blobs in the Azure Storage account would not meet the goal of identifying and deleting blobs that were not modified during the last 100 days.
An expired tag is a label that can be applied to blobs in Azure Storage to indicate that the blob has expired and can be deleted. However, applying an expired tag does not take into account the requirement of identifying and deleting blobs based on their last modification date.
To meet the goal of identifying and deleting blobs that were not modified during the last 100 days, a lifecycle management policy should be implemented on the Azure Storage account. Lifecycle management policies enable you to automatically transition blobs to different access tiers or delete them based on rules that you define.
In this scenario, a lifecycle management policy can be defined to identify blobs that have not been modified in the last 100 days and delete them. The policy can be configured to run daily or on a specified schedule to ensure that blobs that meet the criteria are deleted regularly.
Therefore, the proposed solution of applying an expired tag to blobs in the Azure Storage account would not meet the goal of identifying and deleting blobs that were not modified during the last 100 days, and the answer is B) No.
