An organization wants to prevent employees from sharing sensitive files with external users via SharePoint Online, but they need to allow sharing with a specific external partner for a single project. What is the most efficient configuration?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Best answer
Disable external sharing at the tenant level and enable it only for the specific project site
This approach uses the granular sharing settings in SharePoint Online: a tenant-wide restriction prevents all external sharing by default, and exceptions can be made on a per-site basis, providing a clear, manageable security model.
Distractor review
Change the default sharing link type to 'Specific people' and add the partner's domain to an allow list
This only changes the default link behavior; users could still share with external users using other link types. It does not block external sharing globally.
Distractor review
Apply sensitivity labels with encryption to all files
Sensitivity labels with encryption protect content regardless of sharing, but they do not prevent external sharing of unencrypted files and require user classification, which is less direct than sharing settings.
Distractor review
Configure a DLP policy to block external sharing except for the partner domain
DLP policies can inspect content and block sharing based on rules, but they are event-driven and can be complex to maintain; site-level sharing settings are more straightforward for this requirement.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this MS-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Disable external sharing at the tenant level and enable it only for the specific project site — The most efficient method is to disable external sharing at the tenant level (to enforce the default restriction) and then enable external sharing only on the specific site used for the partner project. This provides a clear security boundary. Changing the default sharing link type does not restrict sharing. Sensitivity labels with encryption can protect content but do not control sharing permissions in the same way. A DLP policy can block external sharing but often requires careful rule configuration and may not be as straightforward as site-level controls.
