The answer is Data Lifecycle Management (DLM) in Microsoft Purview. This solution is correct because it enforces both retention and automated deletion—you configure a retention policy for exactly 7 years, then set a deletion action at the end of that period, which ensures HR documents are kept for the required time and then removed automatically. DLM also locks the retention settings, meaning users cannot permanently delete documents before the retention period ends, overriding their standard delete permissions. On the SC-900 exam, this scenario tests your understanding of how DLM differs from other Purview solutions like Records Management or eDiscovery; a common trap is confusing DLM with a simple retention label, but remember that DLM applies policy-based automation at the container level, not just item-level tags. For a memory tip, think “DLM = Duration, Lock, and auto-Move to deletion”—the lock is what prevents premature deletion, and the auto-delete handles the 7-year cleanup.
SC-900 Practice Question: Describe the capabilities of Microsoft compliance solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft compliance solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company must retain all HR documents stored in SharePoint Online for exactly 7 years. After 7 years, the documents must be automatically deleted. Additionally, employees must not be able to permanently delete these documents before the retention period ends. Which Microsoft Purview solution should they configure?
Data Lifecycle Management provides retention labels and policies that can automatically retain and then delete content after a specified period, and it prohibits users from purging the content during retention.
B
Records Management
Why wrong: Records Management is used to declare documents as permanent records (e.g., regulatory records), but it does not inherently include automatic deletion after a time-based rule.
C
Data Loss Prevention
Why wrong: Data Loss Prevention (DLP) helps prevent sensitive data from being shared or lost; it does not manage retention or deletion.
D
Audit
Why wrong: Audit logs user and admin activities for investigation purposes but does not enforce retention or deletion policies.

Correct answer & explanation
✓
Data Lifecycle Management
Data Lifecycle Management (DLM) in Microsoft Purview is designed to retain content for a specified period and then automatically delete it. By applying a retention policy with a 7-year retention period and a deletion action at the end, DLM ensures HR documents are kept exactly as required. Additionally, DLM prevents users from permanently deleting documents during the retention period by locking the retention settings, which overrides user delete permissions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Records Management with Data Lifecycle Management, assuming that 'records' automatically implies retention and deletion, but Records Management focuses on declaring records and managing disposition reviews, not automatic time-based deletion without user intervention.
Detailed technical explanation
How to think about this question
Under the hood, Data Lifecycle Management uses retention policies that apply to SharePoint Online sites, libraries, or folders, with a retention action that can be set to 'Delete items automatically' after a specified duration. The policy uses a 'preservation hold' mechanism that prevents permanent deletion by users during the retention period, even if they attempt to delete the document; the document is moved to the Preservation Hold library and remains accessible until the retention period expires. In a real-world scenario, if an HR employee tries to delete a performance review document after 3 years, DLM ensures the document is retained in a hidden preservation hold library until the 7-year mark, then automatically purged.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
