The answer is that access is blocked. This occurs because the Microsoft Purview auto-labeling policy rule explicitly combines the condition of detecting a credit card number with the action 'blockAccess' when the document already carries the 'Confidential' label, overriding any default behavior like encryption or notification. On the SC-900 exam, this scenario tests your understanding of how auto-labeling policies enforce conditional access based on sensitive data types and existing labels, often appearing as a trick where candidates assume encryption is the default action. A common trap is confusing 'blockAccess' with 'applyEncryption' or misreading the rule’s priority. Remember the memory tip: “Block the card, not the label”—the action targets the sensitive data condition, not the label itself, so when both a credit card number and the Confidential label are present, the policy blocks access outright.
SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 reviewing a Microsoft Purview auto-labeling policy configuration. Based on the exhibit, what happens when a document contains a credit card number and is labeled 'Confidential'?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Access is blocked
Option B is correct because the rule specifies action 'blockAccess' when condition 'contains Credit Card Number' and label 'Confidential'. Option A is wrong because it blocks, not allows. Option C is wrong because it does not apply encryption; it blocks access. Option D is wrong because it does not notify admin.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.

Real-world example
How this comes up in practice
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.

Variation 1. A company wants to classify and label documents in SharePoint automatically based on sensitive content like social security numbers. Which Microsoft Purview solution should they use?
easy
A.eDiscovery
✓ B.Auto-labeling policy
C.Audit log
D.Data loss prevention policy
Why B: Auto-labeling policies in Microsoft Purview automatically apply sensitivity labels to documents in SharePoint based on sensitive info types. Option B is incorrect because data loss prevention policies can apply labels but are primarily for preventing data leaks. Option C is incorrect because audit logs activities. Option D is incorrect because eDiscovery is for searching and exporting data.
Variation 2. A company wants to automatically classify documents containing credit card numbers and apply encryption at rest in SharePoint Online. Which Microsoft Purview feature should be used?
medium
✓ A.Sensitivity labels with auto-classification
B.eDiscovery
C.Microsoft Purview Audit
D.Data Loss Prevention (DLP) policies
Why A: Sensitivity labels with auto-classification can detect credit card numbers and apply encryption. Option B is correct. Option A (DLP policies) prevent sharing but do not apply encryption. Option C (Audit) logs activities. Option D (eDiscovery) is for legal discovery.
