The answer is Cloud Discovery and Conditional Access App Control. Cloud Discovery identifies shadow IT by analyzing traffic logs from your network firewalls and proxies to reveal which unsanctioned cloud apps are in use, while Conditional Access App Control enforces real-time session policies to block or restrict access to those discovered apps. On the Microsoft Cybersecurity Architect exam, this pairing tests your understanding of how Defender for Cloud Apps bridges visibility and governance—a common trap is confusing DLP policies (which protect data after access) with the discovery and access control functions. Remember the mnemonic “See then Block”: Cloud Discovery sees the shadow IT, and Conditional Access App Control blocks or limits it in real time.
SC-100 Design security solutions for infrastructure Practice Question
This SC-100 practice question tests your understanding of design security solutions for infrastructure. 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 organization is planning to deploy Microsoft Defender for Cloud Apps (formerly Cloud App Security). You need to discover shadow IT usage and control access to cloud apps. Which TWO capabilities should you enable? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Conditional Access App Control
Options A and C are correct. Cloud Discovery (A) identifies shadow IT by analyzing traffic logs. Conditional Access App Control (C) enables real-time session controls. Option B is wrong because DLP policies are for data protection, not discovery or access control. Option D is wrong because device compliance is managed by Intune. Option E is wrong because MCAS does not scan on-premises apps.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Microsoft Intune device compliance policies
Why it's wrong here
Intune manages devices, not cloud app discovery or access control.
✗
Data Loss Prevention (DLP) policies
Why it's wrong here
DLP is for data protection, not for discovery or access control.
✗
On-premises app discovery via Microsoft Defender for Identity
Why it's wrong here
Defender for Identity covers on-premises AD, not cloud app discovery.
✓
Cloud Discovery
Why this is correct
Cloud Discovery identifies cloud app usage and shadow IT.

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.
