The answer is Endpoint Data Loss Prevention (Endpoint DLP) and DLP policies in Microsoft 365. Endpoint DLP directly monitors and blocks the copy, paste, or upload of sensitive data from company-managed devices to personal cloud storage services like Dropbox, while DLP policies in Microsoft 365 extend this protection by scanning and preventing data exfiltration across Exchange, SharePoint, and OneDrive. On the Microsoft Cybersecurity Architect exam, this pairing tests your understanding of layered data protection—Endpoint DLP handles the device-level action, and cloud DLP covers the service-level transmission. A common trap is confusing sensitivity labels (which classify but do not block) or deprecated Azure Information Protection (AIP) with active Purview controls. Remember: to stop data from leaving the endpoint, think Endpoint DLP; to catch it in transit, think cloud DLP policies.
SC-100 Practice Question: Design security solutions for applications and data
This SC-100 practice question tests your understanding of design security solutions for applications and data. 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.
Your company uses Microsoft 365 and wants to prevent sensitive data from being copied to personal cloud storage services like Dropbox. Which TWO Microsoft Purview capabilities should you use?
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) policies in Microsoft Purview
Options B and D are correct. Endpoint DLP can block copying to personal cloud storage from devices, and DLP policies in Microsoft 365 can detect and block such actions. Option A is wrong because sensitivity labels classify but don't block actions. Option C is wrong because AIP is deprecated in favor of Purview. Option E is wrong because Cloud App Security can block downloads from cloud apps but not from endpoint to personal cloud.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Azure Information Protection (AIP) unified labeling client
Why it's wrong here
AIP is deprecated; Purview is the current solution.
✗
Sensitivity labels
Why it's wrong here
Labels classify data but don't block copying to unauthorized locations.
✗
Microsoft Defender for Cloud Apps (formerly Cloud App Security)
Why it's wrong here
Defender for Cloud Apps can control access to cloud apps but not endpoint copy actions.
Common exam traps
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.
Detailed technical explanation
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.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
