The answer is Microsoft Purview Information Barriers and Microsoft Purview Data Loss Prevention (DLP). Information Barriers is the correct solution for the first requirement because it enforces segmentation policies that block all forms of communication—including email, Teams chat, and file sharing—between designated groups, such as legal teams on opposing sides of a lawsuit, by using user-defined segments and policies. DLP addresses the second requirement by scanning outbound emails for sensitive content like a specific case name and automatically blocking or quarantining those messages to prevent external sharing. On the SC-900 exam, this question tests your ability to distinguish between solutions that control internal collaboration versus those that protect data leaving the organization; a common trap is choosing Microsoft Communication Compliance, which monitors communications for policy violations but does not actively block them. Remember the memory tip: Information Barriers builds walls inside the company, while DLP guards the exits.
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 law firm uses Microsoft 365 and has two legal teams working on opposing sides of the same lawsuit. The compliance officer needs to prevent any communication (email, Teams chat, file sharing) between the two teams. Additionally, the firm must block emails containing the case name from being sent outside the organization. Which two Microsoft Purview solutions should be configured to meet these requirements? (Choose two.)
Information Barriers can prevent communication between defined user groups, which is exactly needed to separate the two legal teams.
B
Microsoft Purview Data Loss Prevention (DLP)
DLP policies can detect and block sensitive information such as a case name from being shared externally.
C
Microsoft Purview Communication Compliance
Why wrong: Communication Compliance is used to detect policy violations in communications but does not block communication between groups or block outbound emails.
D
Microsoft Purview Audit (Standard)
Why wrong: Audit only logs activities; it does not enforce communication separation or block data sharing.

Correct answer & explanation
✓
Microsoft Purview Information Barriers
Microsoft Purview Information Barriers (A) is correct because it is specifically designed to prevent communication and collaboration between two groups within an organization, such as legal teams on opposing sides of a lawsuit. It enforces policies that block email, Teams chat, and file sharing between the defined segments, directly meeting the first requirement.
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 Communication Compliance (which reviews communications) with Information Barriers (which blocks communications), or they overlook that DLP is required for the outbound email blocking requirement while Information Barriers handles the internal team separation.
Detailed technical explanation
How to think about this question
Information Barriers uses Azure Active Directory user attributes and segment-based policies to enforce communication blocks at the transport layer for Exchange Online and at the service layer for Teams and SharePoint. For DLP, policies can be configured with conditions that scan email messages for sensitive information types (e.g., a custom keyword like the case name) and apply actions such as 'Block' with an override notification, preventing the email from leaving the organization.

→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.
