This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 protect its SaaS apps. The security team needs to detect when a user downloads more than 100 files from SharePoint Online within 10 minutes. Which policy type should they create?
Anomaly detection policy
Anomaly detection policy uses machine learning to detect unusual user behavior like mass downloads.
Activity policy
Why wrong: Activity policy is for tracking specific activities, not for detecting anomalies.
Threat detection policy
Why wrong: Threat detection policy is for known threats, not behavioral anomalies.
Compliance policy
Why wrong: Compliance policy is for data governance, not behavioral detection.
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 policy
Anomaly detection policies in Defender for Cloud Apps use behavioral analytics to detect unusual patterns like mass file download. Activity policy is for specific activities, but anomaly detection is better for this scenario. Option A is wrong because it's a generic term; Option B is wrong because it's for threat detection; Option D is wrong because it's for compliance.
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.
Anomaly detection policy
Why this is correct
Anomaly detection policy uses machine learning to detect unusual user behavior like mass downloads.
Related concept
Static NAT maps one inside address to one outside address.
Activity policy
Why it's wrong here
Activity policy is for tracking specific activities, not for detecting anomalies.
Threat detection policy
Why it's wrong here
Threat detection policy is for known threats, not behavioral anomalies.
Compliance policy
Why it's wrong here
Compliance policy is for data governance, not behavioral detection.
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 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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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-900 NAT questions on configuration and troubleshooting.
