MS-102 Practice Question: Manage security and threats by using Microsoft Defender XDR
This MS-102 practice question tests your understanding of manage security and threats by using microsoft defender xdr. 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 security administrator needs to discover which cloud apps are being used in the organization and then block usage of unsanctioned apps in real time using a reverse proxy. Which two Microsoft Defender for Cloud Apps features must be configured to meet these requirements? (Select all that apply.)
Cloud Discovery identifies cloud apps being used in the organization.
B
App Connectors
Why wrong: App Connectors connect Defender for Cloud Apps to specific apps via API, enabling deeper control but not discovery or reverse proxy blocking.
C
Conditional Access App Control
Conditional Access App Control uses reverse proxy to block access to unsanctioned apps in real time.
D
API connectors
Why wrong: API connectors are similar to App Connectors; they provide API-based visibility but not discovery or reverse proxy.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cloud Discovery
Cloud Discovery (A) is correct because it analyzes traffic logs from your network to identify all cloud apps in use, providing visibility into sanctioned and unsanctioned apps. Conditional Access App Control (C) is correct because it enforces real-time access controls via a reverse proxy, allowing you to block unsanctioned apps as users attempt to access them.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing App Connectors/API connectors (which provide API-based control for specific apps) with the reverse proxy and discovery capabilities of Cloud Discovery and Conditional Access App Control, leading candidates to select options that manage existing apps rather than discover and block unsanctioned ones.

Detailed technical explanation
How to think about this question
Cloud Discovery works by ingesting firewall and proxy logs (e.g., from Zscaler or Cisco) or using the Cloud Discovery Docker container to analyze traffic against the Defender for Cloud Apps catalog of over 31,000 apps. Conditional Access App Control uses a reverse proxy architecture where traffic is routed through Defender for Cloud Apps, allowing it to inspect HTTP headers and enforce policies like block or session control in real time, leveraging Azure AD Conditional Access policies.

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 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.
