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 block unsanctioned cloud apps in real time using a reverse proxy. Which two Microsoft Defender for Cloud Apps components must be configured?
Cloud Discovery
Why wrong: Cloud Discovery identifies app usage but does not enforce real-time blocks.
Conditional Access App Control
This component enables the reverse proxy for real-time session control.
App governance
Why wrong: App governance manages OAuth app compliance, not traffic blocking.
Session control policies
Session policies define actions like blocking or limiting activities within the app.
Answer choices
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
Conditional Access App Control (B) is the reverse proxy component in Microsoft Defender for Cloud Apps that enforces real-time session-level monitoring and control of cloud app access. Session control policies (D) are the specific policy objects that define the actions (e.g., block download, block access) applied through that reverse proxy. Together, they enable blocking unsanctioned cloud apps in real time by intercepting user traffic via the reverse proxy architecture.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
The trap here is that candidates confuse Cloud Discovery (which only detects unsanctioned apps via log analysis) with the real-time blocking capability, or they assume App governance provides reverse proxy controls when it actually focuses on OAuth app permissions and lifecycle management.
Detailed technical explanation
Conditional Access App Control works by routing user traffic through the Defender for Cloud Apps reverse proxy, which inspects HTTP/HTTPS requests and applies session policies at the application layer. Session control policies can enforce granular actions like blocking file uploads or copy/paste based on user, device, or location attributes, and they integrate with Azure AD Conditional Access to trigger the proxy redirect. In a real-world scenario, an admin can create a session policy that blocks access to a newly discovered unsanctioned file-sharing app within seconds of detection, without requiring changes to network infrastructure.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
