Quick Answer
The answer is anomaly detection policies. This is the correct choice because Microsoft Defender for Cloud Apps uses machine learning and behavioral analytics to establish a baseline of normal user activity, then triggers alerts when deviations occur—such as impossible travel, mass file downloads, or ransomware-like behavior—across connected cloud apps. On the Microsoft Cybersecurity Architect exam, this concept tests your understanding of how to operationalize threat detection in a multi-cloud environment; a common trap is confusing anomaly detection with activity policies, which rely on static rules rather than adaptive baselines. Remember the memory tip: “Anomaly adapts, activity adheres”—anomaly detection learns normal patterns over time, while activity policies simply enforce fixed conditions.
This SC-100 practice question tests your understanding of design solutions that align with security best practices and priorities. 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.
A company deploys Microsoft Defender for Cloud Apps. They need to detect anomalous behavior in user activities across multiple cloud apps. Which feature should they enable?
Session policies
Why wrong: Session policies control access in real time, not detect anomalies.
Anomaly detection policies
This is the correct feature for detecting anomalous user activities.
Data loss prevention policies
Why wrong: DLP policies focus on data protection, not behavioral anomalies.
App governance
Why wrong: App governance manages OAuth apps, not user behavior anomalies.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Anomaly detection policies
Anomaly detection policies in Microsoft Defender for Cloud Apps are specifically designed to identify unusual patterns in user activities across connected cloud apps, such as impossible travel, mass file downloads, or ransomware-like behavior. These policies leverage machine learning and behavioral analytics to establish a baseline of normal user behavior and trigger alerts when deviations occur, making them the correct choice for detecting anomalous 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 policies
Why it's wrong here
Session policies control access in real time, not detect anomalies.
Anomaly detection policies
Why this is correct
This is the correct feature for detecting anomalous user activities.
Related concept

Data loss prevention policies
Why it's wrong here
DLP policies focus on data protection, not behavioral anomalies.
App governance
Why it's wrong here
App governance manages OAuth apps, not user behavior anomalies.
Common exam traps
The trap here is that candidates often confuse session policies (which enforce real-time access controls) with anomaly detection policies (which analyze historical patterns), leading them to select session policies when the question specifically asks for detecting anomalous behavior rather than controlling it.
Detailed technical explanation
Anomaly detection policies in Defender for Cloud Apps use a combination of UEBA (User and Entity Behavior Analytics) and machine learning models to profile each user's typical activity, including login times, locations, and app usage. For example, the 'Impossible travel' policy detects logins from geographically distant locations within a time window that would be physically impossible, using IP geolocation and time zone data. This feature also integrates with Microsoft Entra ID (formerly Azure AD) to correlate identity risk signals, enabling automated remediation like requiring MFA or blocking access.
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.

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 organization uses Microsoft Defender for Cloud Apps. You need to detect anomalous behavior such as impossible travel. What should you configure?
easyWhy A: Option A is correct because Microsoft Defender for Cloud Apps uses anomaly detection policies to detect impossible travel and other suspicious activities. Option B is wrong because DLP policies focus on data protection, not activity anomalies. Option C is wrong because app permissions are for OAuth apps. Option D is wrong because session policies control real-time access, not anomaly detection.
