Quick Answer
The correct choice is an activity policy, because it is specifically designed in Microsoft Defender for Cloud Apps to monitor user behaviors like file downloads and trigger alerts when a defined threshold is exceeded within a short time window. Unlike other policy types, such as anomaly detection or session policies, an activity policy allows you to set precise conditions—for example, “more than 50 file downloads from SharePoint Online in 10 minutes”—and respond with governance actions like suspending the user or requiring re-authentication. On the SC-200 exam, this question tests your ability to distinguish between Defender for Cloud Apps policy types, often presenting a trap where candidates confuse activity policies with anomaly detection policies; remember that anomaly detection uses built-in machine learning, while activity policies rely on manually configured thresholds. A useful memory tip: think of “activity” as “action with a number”—if you can set a specific count or rate, it’s an activity policy.
This SC-200 practice question tests your understanding of manage a security operations environment. 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 SOC uses Microsoft Sentinel and Microsoft Defender for Cloud Apps. You need to configure a policy that triggers when a user downloads a large number of files from SharePoint Online within a short period. Which policy type should you use?
Session policy
Why wrong: Session policies control access but do not trigger alerts for past downloads.
File policy
Why wrong: File policies are for file attributes, not activity patterns.
Anomaly detection policy
Why wrong: Anomaly detection policies are predefined and not as customizable for specific app behaviors.
Activity policy
Activity policies allow custom detection of specific activities like mass downloads.

Correct answer & explanation
Activity policy
An activity policy in Microsoft Defender for Cloud Apps is designed to monitor and respond to specific user activities, such as downloading a large number of files from SharePoint Online within a short period. This policy type allows you to set thresholds and triggers based on user actions, making it the correct choice for detecting anomalous download behavior.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Session policy
Why it's wrong here
Session policies control access but do not trigger alerts for past downloads.
File policy
Why it's wrong here
File policies are for file attributes, not activity patterns.
Anomaly detection policy
Why it's wrong here
Anomaly detection policies are predefined and not as customizable for specific app behaviors.
Activity policy
Why this is correct
Activity policies allow custom detection of specific activities like mass downloads.

Common exam traps
The trap here is that candidates often confuse anomaly detection policies (which are predefined and use machine learning) with activity policies (which are customizable and rule-based), leading them to select anomaly detection when a custom threshold-based trigger is required.
Detailed technical explanation
Activity policies in Microsoft Defender for Cloud Apps leverage the Cloud App Security API to monitor user activities across connected apps like SharePoint Online. When configuring such a policy, you can set parameters like 'Activity type' (e.g., 'Download file'), 'Activity count' (e.g., '>100'), and 'Time frame' (e.g., '5 minutes'), which are evaluated against the activity log. This granular control allows SOC teams to create custom alerts for suspicious behavior, such as potential data exfiltration, without relying on predefined machine learning models.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Variation 1. Your organization uses Microsoft Defender for Cloud Apps. You need to create a policy that alerts when a user downloads more than 10 files from SharePoint in 5 minutes. What type of policy should you create?
mediumWhy A: An activity policy in Defender for Cloud Apps monitors specific user activities and can trigger alerts based on frequency thresholds. Option A is wrong because Anomaly detection policies use machine learning. Option C is wrong because Session policies control activities in real-time via proxy. Option D is wrong because App permissions policies manage OAuth apps.
