A multinational corporation needs to ensure that all emails containing a customer's passport number are automatically blocked from being sent externally. Additionally, the sending user should receive a policy tip explaining the block. Which Microsoft Purview solution should be configured?
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.
Distractor review
Sensitivity labels
Sensitivity labels classify and protect documents but do not block emails from being sent based on content.
Best answer
Data Loss Prevention (DLP) policies
DLP policies can detect passport numbers in emails and block them from being sent, with user notification via policy tips.
Distractor review
Conditional Access policies
Conditional Access controls access to apps and data based on conditions like location or device, not email content.
Distractor review
eDiscovery
eDiscovery is used for legal hold and search of content, not for blocking email transmission in real time.
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) policies — Data Loss Prevention (DLP) policies can be configured to detect sensitive information types like passport numbers in emails and block transmission with a customizable policy tip to the user. Sensitivity labels do not block transmission; they apply protection after the fact. Conditional Access controls access at sign-in, not content in emails. eDiscovery is for legal discovery, not blocking emails.
