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 company wants to automatically detect emails in Exchange Online that contain credit card numbers and apply encryption to those emails before they are sent. Which Microsoft Purview solution should the administrator configure?
Why wrong: Sensitivity labels classify and protect data, but they do not automatically detect and encrypt emails based on sensitive content in transit; DLP is designed for that.
B
Data Loss Prevention (DLP)
DLP policies can inspect emails for sensitive data patterns (e.g., credit card numbers) and automatically apply encryption as a protective action.
C
Data Lifecycle Management
Why wrong: Data Lifecycle Management handles retention and deletion policies, not real-time detection and encryption of sensitive content.
D
eDiscovery
Why wrong: eDiscovery is used for legal holds, searches, and exporting data, not for preventing data leakage by detecting sensitive information in transit.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Data Loss Prevention (DLP)
Data Loss Prevention (DLP) in Microsoft Purview is specifically designed to detect sensitive information such as credit card numbers in emails and automatically apply protective actions like encryption. DLP policies can scan Exchange Online messages in transit and enforce rules to encrypt the email before it is sent, which directly meets the requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Information Protection (sensitivity labels)
Why it's wrong here
Sensitivity labels classify and protect data, but they do not automatically detect and encrypt emails based on sensitive content in transit; DLP is designed for that.
✓
Data Loss Prevention (DLP)
Why this is correct
DLP policies can inspect emails for sensitive data patterns (e.g., credit card numbers) and automatically apply encryption as a protective action.

eDiscovery
Why it's wrong here
eDiscovery is used for legal holds, searches, and exporting data, not for preventing data leakage by detecting sensitive information in transit.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse sensitivity labels (which can also apply encryption) with DLP, but sensitivity labels require manual or automatic classification based on label policies, not real-time content scanning of specific sensitive data patterns like credit card numbers in transit.
Detailed technical explanation
How to think about this question
DLP in Exchange Online uses deep content analysis via transport rules and data classification service to match credit card numbers against predefined or custom sensitive information types (e.g., using Luhn checksum validation). When a match occurs, the DLP policy can invoke Information Rights Management (IRM) to encrypt the email using Azure Rights Management (Azure RMS), ensuring the message is protected even if forwarded or accessed outside the organization.
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.
