Microsoft Purview retention labels control how long content must be preserved and what action occurs after the configured retention period expires.

Option B is the intended examination answer, based on the default retention-period start date.

The exhibit shows Retention1 configured with a six-month retention period and the Retain and Delete action.

Microsoft documents that retention periods start from the content creation date by default, unless the label is explicitly configured to use another trigger.

File1 was created on January 1, 2025. Therefore, its six-month retention period ends on July 1, 2025.

The modification on January 10 does not reset the retention period under the default configuration. Similarly, deleting File1 on February 1 does not override the retention requirement.

Option A ignores the retention configuration. Option C would apply if retention began on the last modification date. Option D incorrectly calculates six months from the user-initiated deletion.

Important technical distinction: The question says permanently and unrecoverable. Microsoft ' s current SharePoint and OneDrive documentation states that retained content is subsequently moved through the Recycle Bin, where an additional 93-day recovery period can apply. Consequently, July 2025 represents the intended retention expiration and deletion processing date, not necessarily the final irreversible deletion date. Strictly interpreted, none of the options guarantees that outcome.
