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. 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.
Your company uses Microsoft Intune to manage mobile devices. You need to protect corporate data on mobile devices by ensuring that work files are encrypted and not accessible by personal apps. What three configurations should you implement? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable mobile threat defense (MTD) integration to block risky devices.
Options A, B, and C are correct. App protection policies (MAM) prevent data from being copied to personal apps. Conditional Access with 'Require app protection policy' ensures managed apps are used. Mobile threat defense integration adds security. Option D is wrong because device encryption is device-level, not app-level. Option E is wrong because compliance policies are for device compliance, not data protection on unmanaged devices.
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.
✗
Require device encryption on all devices.
Why it's wrong here
Device encryption does not isolate work and personal data.
✓
Enable mobile threat defense (MTD) integration to block risky devices.
Why this is correct
MTD adds security by detecting threats.

✗
Deploy a device compliance policy that requires a PIN.
Why it's wrong here
Compliance policies are for device-level access, not data protection.
✓
Create an app protection policy (MAM) that encrypts work data and prevents save-as to personal locations.
Why this is correct
MAM policies protect app-level data.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
