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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 financial company needs to prevent any communication between their mergers and acquisitions (M&A) team and the trading desk across all Microsoft 365 channels, including email, Microsoft Teams, and SharePoint. They must ensure that no user in one group can send emails to or chat with users in the other group. Which Microsoft Purview solution should they implement?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Information Barriers
Information Barriers (IB) is the correct solution because it is specifically designed to prevent communication and collaboration between two user groups across Microsoft 365 services, including email, Teams, and SharePoint. By defining policies that block segments (e.g., M&A team and trading desk), IB enforces restrictions at the transport, chat, and document level, ensuring no email, chat, or file sharing occurs between the groups. This directly addresses the requirement to isolate the M&A team from the trading desk across all channels.
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 Information Barriers with Communication Compliance, mistakenly thinking that monitoring and blocking are the same, but Communication Compliance only detects and reports violations after the fact, whereas Information Barriers proactively prevents communication from occurring.
Detailed technical explanation
How to think about this question
Information Barriers uses segments and policies defined in the Microsoft Purview compliance portal, leveraging Azure Active Directory user attributes (e.g., department, job title) to create segments. Policies are enforced at the transport layer for Exchange Online (blocking email send/receive), at the chat layer for Teams (blocking 1:1 chat, group chat, and channel participation), and at the SharePoint layer (blocking site access and sharing). A subtle behavior is that IB policies can take up to 30 minutes to propagate after creation, and they require users to be assigned an appropriate license (e.g., Microsoft 365 E5 or A5).
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.
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.
