Explanation

This question tests knowledge of Azure Blob Storage point-in-time restore prerequisites, specifically what blob type supports this feature and what account-level setting must be enabled alongside blob versioning and soft delete.

Approach. For point-in-time restore in Azure Blob Storage, you must use Block Blobs - point-in-time restore only supports block blobs and does not apply to append blobs or page blobs. Additionally, you must enable Change Feed on the storage account, as point-in-time restore relies on the change feed log (combined with blob versioning and blob soft delete) to track and replay blob state changes to a specific point in time. So the correct answers are: Blob type = Block Blob, and the feature to enable = Change Feed. Together, blob versioning, blob soft delete, change feed, and point-in-time restore form a set of interdependent data protection features that must all be enabled for the solution to work.

Concept tested. Azure Blob Storage point-in-time restore requirements: understanding that only block blobs are supported, and that Change Feed must be enabled alongside blob versioning and blob soft delete to facilitate point-in-time restore functionality.
