Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Best answer

Data Loss Prevention (DLP)

DLP policies can identify sensitive data like credit card numbers in email and block the message from being sent.

B

Distractor review

Information Rights Management (IRM)

IRM restricts actions on content after it is received (e.g., prevent forwarding), but does not block outbound email based on sensitive data patterns.

C

Distractor review

Sensitivity labels

Sensitivity labels classify and protect content but are not designed to block email transmission; they rely on label-based policies (like DLP) for enforcement.

D

Distractor review

Microsoft Defender for Office 365 (ATP)

ATP protects against phishing and malware, not against sharing sensitive data in email content.

Common exam trap

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.

Technical deep dive

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.

FAQ

Questions learners often ask

What does this MS-900 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: Data Loss Prevention (DLP) — Data Loss Prevention (DLP) policies in Microsoft Purview can inspect email content for sensitive data patterns (e.g., credit card numbers) and automatically block sending the email or notify the user. Information Rights Management (IRM) protects content after it is shared but does not detect or block real-time sharing. Sensitivity labels classify content but require manual application or auto-labeling, and do not directly block email transmission. Advanced Threat Protection (ATP) focuses on malicious links and attachments, not sensitive data leakage.
