You need to configure lifecycle management for blobs in a storage account. Which policy allows you to automatically delete old snapshots?

Correct answer: Lifecycle management policy

Option C is correct because Azure Blob Storage Lifecycle Management policies allow you to define rules that automatically transition or delete blobs, versions, and snapshots based on age or last-modified conditions, including a specific action to delete snapshots after a configurable number of days. Option A is incorrect because redundancy policies control data replication (LRS, GRS, ZRS) for durability and availability, not automated data deletion. Option B is incorrect because archive policies transition blobs to the Archive access tier to reduce storage costs but do not automatically delete old snapshots. Option D is incorrect because blob retention policies (as part of immutable storage or soft-delete retention) govern how long deleted data is recoverable, not the automated deletion of aged snapshots.
