MS-900 Practice Question: Describe security, compliance, privacy, and trust in Microsoft 365
This MS-900 practice question tests your understanding of describe security, compliance, privacy, and trust in microsoft 365. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 legal team needs to ensure that all documents related to an ongoing case are retained for exactly 7 years and then automatically deleted. During the retention period, no user should be able to permanently delete these documents. Which two Microsoft Purview features should be used together to meet this requirement? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Retention policy
A retention policy is correct because it can be applied at the site or folder level to enforce a mandatory 7-year retention period for all documents in a location, such as a SharePoint site for the legal case. It prevents users from permanently deleting documents during the retention period by blocking deletion actions and preserving the content in a preservation hold library.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Litigation hold
Why it's wrong here
Litigation hold preserves content indefinitely until the hold is released, which conflicts with the requirement to delete after 7 years.
✗
Data loss prevention (DLP) policy
Why it's wrong here
DLP policies are designed to prevent sensitive information from being shared, not to manage retention or deletion.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Litigation hold with a time-based retention policy, not realizing that Litigation hold is indefinite and requires manual release, whereas a retention policy can enforce a specific duration with automatic deletion.
Detailed technical explanation
How to think about this question
Retention policies in Microsoft Purview use a preservation hold library in SharePoint and OneDrive to store a copy of the document when a user attempts to delete or modify it, ensuring the original version remains accessible during the retention period. The policy can be configured with a specific duration (e.g., 7 years) and an action to automatically delete the content after that period, using the 'Delete' action in the retention settings. This works by applying a timer job that checks the retention age and triggers permanent deletion from the preservation hold library once the period expires.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
