Quick Answer
The answer is an activity policy, as this is the specific Defender for Cloud Apps configuration designed to detect mass download data exfiltration from SharePoint Online. An activity policy monitors user actions in real time against defined parameters, such as downloading a large number of files within a short window, and triggers an alert when the threshold is exceeded. This directly addresses the need to catch anomalous bulk downloads that signal potential data theft. For the MS-102 exam, remember that activity policies are for unusual user actions like mass downloads, while anomaly detection covers broader behavioral patterns like impossible travel, file policies focus on sharing permissions, and session policies control real-time access. A common trap is confusing activity policies with anomaly detection—think of activity as a specific rule you set, while anomaly is a built-in AI model. Memory tip: “Activity catches the action, anomaly catches the pattern.”
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 company uses Microsoft Defender for Cloud Apps to monitor cloud app usage. They want to receive alerts when a user downloads a large number of files from SharePoint Online in a short time, which could indicate data exfiltration. What should they configure?
Session policy
Why wrong: Session policies control access in real time.
Anomaly detection policy
Why wrong: Anomaly detection is for user behavior anomalies.
File policy
Why wrong: File policies monitor file sharing.
Activity policy
Activity policies can detect mass download.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Activity policy
An activity policy can detect anomalous activities like mass download. Option B is correct. Option A is wrong because anomaly detection is for user behavior like impossible travel. Option C is wrong because file policies monitor sharing. Option D is wrong because a session policy controls access.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Your company uses Microsoft Defender for Cloud Apps. You notice that a user is downloading large amounts of data from a sanctioned cloud app from an unusual location. You need to automatically suspend the user's access when such activity is detected. What should you configure?
mediumWhy C: Option B is correct because session policies in Defender for Cloud Apps can monitor and control user activities in real time and take actions like suspending access. Option A is wrong because access policies are for conditional access, not real-time session control. Option C is wrong because file policies govern file sharing, not user sessions. Option D is wrong because anomaly detection alerts but does not automatically suspend access.
Variation 2. Your organization uses Microsoft Defender for Cloud Apps. You discover that a user is downloading large amounts of data from SharePoint Online to an unmanaged device. You need to automatically block the download and alert the security team. What should you configure?
mediumWhy A: Option B is correct because a session policy can control access and block downloads in real-time. Option A is wrong because an anomaly detection policy only alerts, it does not block. Option C is wrong because an access policy can block access entirely, but not specifically block downloads. Option D is wrong because a file policy monitors file activities but does not block downloads real-time.
