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. A key principle to apply: dLP policies detect sensitive information like credit card numbers.. 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.

Answer choices

Why each option matters

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 (DLP)

Microsoft Purview Data Loss Prevention (DLP) is the correct solution because it is specifically designed to detect sensitive information types—such as credit card numbers—in documents and communications. DLP policies can be configured to block or warn users via policy tips when they attempt to share such content through email or Microsoft Teams, enforcing compliance without disrupting legitimate work.

Key principle: DLP policies detect sensitive information like credit card numbers.

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 Information Barriers

    Why it's wrong here

    Information barriers are used to prevent communication between certain user groups (e.g., departments), not to scan content for sensitive data.

  • Microsoft Purview Data Loss Prevention (DLP)

    Why this is correct

    DLP policies can detect credit card numbers and other sensitive data in Exchange, SharePoint, OneDrive, and Teams. They can block the action and display a policy tip to inform the user.

    Related concept

    DLP policies detect sensitive information like credit card numbers.

  • Microsoft Purview Retention Policies

    Why it's wrong here

    Retention policies are used to retain or delete data after a specified period, not to prevent sharing or detect sensitive content.

  • Microsoft Purview Sensitivity Labels

    Why it's wrong here

    Sensitivity labels classify and protect data by applying encryption or markings, but they do not actively block sharing or show policy tips when users attempt to share. DLP is the solution for that behavior.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse Sensitivity Labels (which classify data) with DLP (which enforces actions based on that classification or on sensitive data patterns), leading them to choose D when the question specifically asks for a solution that scans for credit card numbers and shows policy tips.

Detailed technical explanation

How to think about this question

DLP policies in Microsoft 365 use built-in sensitive information types (e.g., Credit Card Number, defined by regex patterns and checksum validation per ISO 7812) to scan content in Exchange Online, SharePoint, OneDrive, and Teams. When a policy tip is triggered, the user sees a customizable notification in Outlook or Teams before the content is sent, and the action can be blocked or allowed with an override justification. In a real-world scenario, a DLP policy can also be configured to automatically encrypt the document or notify a compliance officer if a user repeatedly attempts to share credit card data.

KKey Concepts to Remember

  • DLP policies detect sensitive information like credit card numbers.
  • DLP can block sharing actions in Exchange, SharePoint, OneDrive, and Teams.
  • DLP policies can display policy tips to users explaining restrictions.
  • DLP uses sensitive information types, keywords, or regular expressions for detection.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

DLP policies detect sensitive information like credit card numbers.

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. DLP policies detect sensitive information like credit card numbers. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
