SC-900 Practice Question: Describe the concepts of security, compliance, and identity
This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. 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.
An organization uses Microsoft Purview to manage data compliance. They need to automatically detect and protect credit card numbers stored in SharePoint Online. Which Microsoft Purview solution should they implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Purview Data Loss Prevention
Data Loss Prevention (DLP) policies can identify sensitive data like credit card numbers and apply protection actions such as blocking access. Information Protection (sensitivity labels) classifies data but does not automatically detect and protect specific patterns like credit card numbers without DLP integration.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Microsoft Purview Audit
Why it's wrong here
Audit logs user activity but does not detect or protect sensitive data.
✓
Microsoft Purview Data Loss Prevention
Why this is correct
DLP policies can detect credit card numbers using built-in sensitive info types and take protective actions.
Related concept
Static NAT maps one inside address to one outside address.
✗
Microsoft Purview Information Protection
Why it's wrong here
Information Protection uses sensitivity labels but requires DLP to detect specific data patterns.
✗
Microsoft Purview Data Lifecycle Management
Why it's wrong here
Data Lifecycle Management focuses on retention and deletion, not detection of sensitive data.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
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.
