MS-900 Practice Question: Describe security, compliance, privacy, and trust in Microsoft 365
During requirements gathering, an IT manager says the organization must review employee messages for harassment or regulatory policy violations. Microsoft security, identity, or compliance capability should it use?
⚠ Common exam trap
Watch out — candidates often confuse Communication Compliance with other Microsoft 365 tools that have 'communication' in their name (like Microsoft Teams) or assume any Microsoft 365 app can be repurposed for compliance, but only Communication Compliance provides the dedicated policy-based message surveillance and remediation workflow required for harassment and regulatory monitoring.
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
✓
Communication Compliance
Communication Compliance in Microsoft 365 is the correct capability because it is specifically designed to detect, capture, and act on inappropriate messages—such as harassment or regulatory policy violations—across email, Microsoft Teams, and third-party communications. It uses configurable policies with built-in classifiers for harassment, threats, and regulatory compliance, enabling automated review and remediation. This directly addresses the IT manager's requirement to monitor employee messages for policy violations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Forms
Why it's wrong here
Microsoft Forms is a lightweight app for building surveys and quizzes, so it captures structured answers in spreadsheets but cannot apply communication policies to email, chat, or posts. It has no role-based review workflow, no content classifiers for harassment or regulatory language, and no integration with supervision pipelines. Therefore, it cannot satisfy a requirement for detecting and routing risky communications.
- ✓
Communication Compliance
Why this is correct
Communication Compliance is the Microsoft Purview solution designed to detect, capture, and route potentially inappropriate or regulated communications for review. It uses configurable policies and machine-learning classifiers to flag harassment, threats, conflict of interest, or insider trading across Exchange, Teams, and third-party feeds. Because the IT manager needs a compliance capability to monitor and moderate communications, this is the correct choice.
- ✗
Microsoft Stream
Why it's wrong here
Microsoft Stream is an enterprise video portal where users store, share, and stream recorded or live content; its features center on playback, transcription, and engagement analytics, not on policy-based communication monitoring. Stream does not parse conversations or route messages to human reviewers for compliance decisions. Thus, it cannot meet a security or compliance requirement tied to detecting problematic communications.
- ✗
Microsoft Planner
Why it's wrong here
Microsoft Planner is a Kanban-style task management tool that helps teams organize work into buckets, assign tasks, and track due dates, but it includes no data-loss prevention, retention, or supervision controls. Planner lacks the underlying compliance engine to scan communication channels and initiate review workflows. So it cannot serve as the mechanism for detecting and managing policy-violating messages.
