- A
Create a DLP policy in Microsoft Purview that blocks sharing of credit card numbers in Teams and does not allow overrides. Configure the policy to apply to all content.
Why wrong: No override allowed, and applies to all content, not just labeled documents.
- B
Configure a session policy in Microsoft Defender for Cloud Apps that monitors Teams for credit card numbers and blocks sharing. Use the 'Block with override' action.
Why wrong: Defender for Cloud Apps is not the primary tool for DLP in Teams; Purview is correct.
- C
Create a DLP policy in Microsoft Purview that blocks sharing of credit card numbers in Teams and allows overrides with business justification. Configure the policy to apply to content containing the 'Financial-Confidential' sensitivity label.
Meets all requirements.
- D
Use the built-in DLP template for financial data in Microsoft Purview and enable the 'Block with override' action. Set the scope to Teams.
Why wrong: Built-in templates may not automatically use custom sensitivity labels.
Quick Answer
The correct answer is to create a DLP policy in Microsoft Purview that blocks sharing of credit card numbers in Teams and allows overrides with business justification, configured to apply to content containing the 'Financial-Confidential' sensitivity label. This works because the policy uses a condition for the custom sensitivity label, ensuring only documents auto-labeled as 'Financial-Confidential' are subject to the rule, while the 'Block with override' action permits users to bypass the block by providing a business justification. On the SC-900 exam, this scenario tests your understanding of how Microsoft Purview DLP policies integrate with sensitivity labels from Microsoft Information Protection, and it often appears as a trick where candidates confuse the administrative center—remember, DLP policies are configured in Purview, not Defender for Cloud Apps. A common trap is choosing a built-in template that lacks the custom label condition, so always verify that the policy explicitly references the specific sensitivity label. Memory tip: think "Label + Override = Compliant Sharing" to recall that a custom label condition paired with an override action meets both security and user flexibility requirements.
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. 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.
Contoso Ltd. is a financial services company that must comply with strict regulatory requirements. They use Microsoft 365 E5, Microsoft Entra ID P2, Microsoft Purview, and Microsoft Defender for Cloud Apps. The compliance team needs to implement a data loss prevention (DLP) policy that detects and prevents the sharing of credit card numbers in Microsoft Teams messages. Additionally, they want to ensure that only users with a specific custom sensitivity label can access documents containing credit card numbers. The sensitivity label is named 'Financial-Confidential' and is applied automatically via auto-labeling. The DLP policy should block sharing of credit card numbers in Teams but allow users to override the block with a business justification. Which combination of actions should you configure in the Microsoft Purview DLP policy to meet these requirements?
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
Create a DLP policy in Microsoft Purview that blocks sharing of credit card numbers in Teams and allows overrides with business justification. Configure the policy to apply to content containing the 'Financial-Confidential' sensitivity label.
Option B is correct. A custom DLP policy with a condition for credit card numbers and the action 'Block with override' will block sharing and allow override. Also, the sensitivity label condition ensures that only documents with 'Financial-Confidential' label are subject to the policy. Option A is wrong because blocking without override does not allow business justification. Option C is wrong because using a built-in DLP template may not integrate with the custom sensitivity label. Option D is wrong because configuring the policy in Defender for Cloud Apps is unnecessary; Microsoft Purview is the correct administrative center for DLP.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a DLP policy in Microsoft Purview that blocks sharing of credit card numbers in Teams and does not allow overrides. Configure the policy to apply to all content.
Why it's wrong here
No override allowed, and applies to all content, not just labeled documents.
- ✗
Configure a session policy in Microsoft Defender for Cloud Apps that monitors Teams for credit card numbers and blocks sharing. Use the 'Block with override' action.
Why it's wrong here
Defender for Cloud Apps is not the primary tool for DLP in Teams; Purview is correct.

Why this is correct
Meets all requirements.
Related concept

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.
