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 protect sensitive data. You need to create a sensitivity label that automatically encrypts documents containing credit card numbers when they are shared externally. Which configuration should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an auto-labeling policy that applies a label with encryption for external sharing
Auto-labeling in Purview can be configured to apply a sensitivity label based on sensitive info types like credit card numbers. The label should have encryption enabled for external sharing. The other options describe different scenarios: manual labeling, default labeling, or classification without encryption.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example
How this comes up in practice
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.
