- A
Data Lifecycle Management
Why wrong: Data Lifecycle Management manages retention and deletion of data based on policies. It does not detect or block sharing of sensitive data in real time.
- B
Data Loss Prevention (DLP)
DLP policies detect sensitive information (e.g., credit card numbers) and enforce actions such as blocking, encrypting, or notifying users. This matches the scenario requirements.
- C
Information Protection (Sensitivity labels)
Why wrong: Sensitivity labels classify and protect documents and emails, but they do not automatically detect and block sharing of credit card numbers unless combined with auto-labeling or DLP.
- D
Insider Risk Management
Why wrong: Insider Risk Management identifies risky user activities (e.g., data exfiltration) but is not designed for real-time blocking of messages containing specific sensitive data types.
Quick Answer
The answer is Microsoft Purview Data Loss Prevention (DLP), which is the correct solution because it is specifically designed to detect, block, and notify users when sensitive data—such as credit card numbers—is shared in emails or Microsoft Teams messages. DLP policies can be configured with built-in sensitive information types like the credit card number entity, and they allow actions such as blocking the message and sending a policy tip to the sender, directly addressing the need to dlp block credit card sharing in teams. On the SC-900 exam, this scenario tests your understanding of how DLP policies apply across Microsoft 365 workloads, often appearing as a scenario-based question where you must distinguish DLP from other solutions like Microsoft Purview Information Protection or Insider Risk Management. A common trap is confusing DLP with encryption or sensitivity labels, but remember: DLP is about preventing data from being shared in the first place, not just protecting it after the fact. Memory tip: DLP = "Don't Let it Pass"—it blocks the message and notifies the sender.
SC-900 Practice Question: Describe the capabilities of Microsoft compliance solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft compliance 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.
A company uses Microsoft 365 and wants to automatically detect when employees attempt to share credit card numbers in emails or Microsoft Teams messages. The company also wants to block the message if it contains such sensitive data, and notify the sender with a policy tip. Which Microsoft Purview solution should the administrator configure?

Correct answer & explanation
Data Loss Prevention (DLP)
Microsoft Purview Data Loss Prevention (DLP) is the correct solution because it is specifically designed to detect, block, and notify users when sensitive data—such as credit card numbers—is shared in emails or Teams messages. DLP policies can be configured with built-in sensitive information types (e.g., credit card number) and actions like blocking the message and sending a policy tip to the sender.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Data Lifecycle Management
Why it's wrong here
Data Lifecycle Management manages retention and deletion of data based on policies. It does not detect or block sharing of sensitive data in real time.
- ✓
Data Loss Prevention (DLP)
Why this is correct
DLP policies detect sensitive information (e.g., credit card numbers) and enforce actions such as blocking, encrypting, or notifying users. This matches the scenario requirements.

Information Protection (Sensitivity labels)
Why it's wrong here
Sensitivity labels classify and protect documents and emails, but they do not automatically detect and block sharing of credit card numbers unless combined with auto-labeling or DLP.

Insider Risk Management
Why it's wrong here
Insider Risk Management identifies risky user activities (e.g., data exfiltration) but is not designed for real-time blocking of messages containing specific sensitive data types.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Information Protection (sensitivity labels) with DLP, not realizing that sensitivity labels classify and protect data at rest, while DLP actively monitors and controls data in motion (email and chat).
Detailed technical explanation
How to think about this question
DLP policies in Microsoft Purview use deep content analysis via the Classification Engine, which scans for sensitive information types defined by regex patterns and keyword lists (e.g., credit card numbers validated with the Luhn algorithm). When a policy tip is triggered, the sender sees a customizable notification in Outlook or Teams before the message is sent, and the message can be blocked entirely or allowed with an override. In a real-world scenario, an administrator can fine-tune DLP rules to exclude false positives by adjusting the confidence level or instance count.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
