This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. 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.
Your organization uses Microsoft Purview to label and protect sensitive data. The compliance team wants to automatically apply a 'Confidential' label to documents containing personally identifiable information (PII) stored in SharePoint Online. What should they create?
A DLP policy to detect PII
Why wrong: DLP policies detect and block, not label.
A trainable classifier for PII
Why wrong: Trainable classifiers identify content but do not apply labels.
A retention label policy for PII
Why wrong: Retention labels manage retention, not classification.
An auto-labeling policy for sensitivity labels
Auto-labeling applies labels automatically to detected sensitive data.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
An auto-labeling policy for sensitivity labels
Auto-labeling policies can automatically apply sensitivity labels to documents based on sensitive information types. Option B is incorrect because retention labels are for retention. Option C is incorrect because trainable classifiers are for pattern detection but do not apply labels automatically. Option D is incorrect because DLP policies block actions.
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.
A DLP policy to detect PII
Why it's wrong here
DLP policies detect and block, not label.
A trainable classifier for PII
Why it's wrong here
Trainable classifiers identify content but do not apply labels.
A retention label policy for PII
Why it's wrong here
Retention labels manage retention, not classification.
An auto-labeling policy for sensitivity labels
Why this is correct
Auto-labeling applies labels automatically to detected sensitive data.
Related concept
Static NAT maps one inside address to one outside address.
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.
