Quick Answer
The correct choice is an activity policy because it allows you to define specific criteria—such as a user accessing SharePoint from a location not on your allowed list—and trigger an alert when that exact activity occurs. Unlike anomaly detection policies, which rely on machine learning to identify broad behavioral deviations, activity policies are rule-based and ideal for precise, location-based detection rules. On the SC-200 exam, this distinction is frequently tested to ensure you understand when to use a deterministic rule versus a machine-learning approach; a common trap is confusing activity policies with anomaly policies, which would not enforce a strict allowlist. Remember the memory tip: if you can write the condition as an if-then statement (e.g., if location not in allowed list, then alert), you need an activity policy.
This SC-200 practice question tests your understanding of manage a security operations environment. 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.
You are a SOC analyst investigating an incident where a user's credentials were used to access a sensitive SharePoint site from an unusual location. Microsoft Defender for Cloud Apps detected the activity as a suspicious sign-in. You need to create a detection rule that alerts whenever a user accesses SharePoint from a location not in the allowed list. What type of rule should you create in Microsoft Defender for Cloud Apps?
App discovery policy.
Why wrong: App discovery policies are for discovering cloud apps used in the organization.
Session policy.
Why wrong: Session policies control access in real time, not detect past activities.
Activity policy.
Activity policies allow you to define conditions like location and trigger alerts.
Anomaly detection policy.
Why wrong: Anomaly detection is based on machine learning profiles, not static location lists.
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.
Activity policies in Defender for Cloud Apps allow you to detect specific user activities that match criteria. Option B is correct. Option A is wrong because anomaly detection policies use machine learning to detect unusual patterns, not specific location-based checks. Option C is wrong because app discovery policies are for discovering shadow IT. Option D is wrong because session policies are for real-time session control, not detection.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
App discovery policy.
Why it's wrong here
App discovery policies are for discovering cloud apps used in the organization.
Session policy.
Why it's wrong here
Session policies control access in real time, not detect past activities.
Activity policy.
Why this is correct
Activity policies allow you to define conditions like location and trigger alerts.
Related concept
Static NAT maps one inside address to one outside address.
Anomaly detection policy.
Why it's wrong here
Anomaly detection is based on machine learning profiles, not static location lists.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SC-200 NAT questions on configuration and troubleshooting.
