SC-900 Practice Question: Describe the capabilities of Microsoft security solutions

This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

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

✓

It blocks the sending of an email if it contains 10 or more credit card numbers with high confidence

Option A is correct because the JSON rule defines a condition where the DLP policy blocks email transmission when the count of credit card numbers detected with high confidence meets or exceeds 10. The 'BlockAccess' action in the rule enforces this by preventing the email from being sent, and the 'NotifyUser' action with 'NotifyOnly' set to false ensures the user is notified of the block. This matches the behavior of a Microsoft Purview DLP policy that uses a threshold-based condition with high confidence to block sensitive data sharing.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    It blocks the sending of an email if it contains 10 or more credit card numbers with high confidence

    Why this is correct

    The condition specifies instanceCount 10 and high confidence, and the action is BlockAccess.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    It notifies the user when a single credit card number is detected in email

    Why it's wrong here

    The action is BlockAccess, not notify, and the threshold is 10.

  • ✗

    It triggers a policy tip when a single credit card number is detected

    Why it's wrong here

    The action is BlockAccess, and the threshold is 10, not 1.

  • ✗

    It blocks access to a SharePoint site containing credit card numbers

    Why it's wrong here

    The location is Exchange, not SharePoint.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse the 'NotifyUser' action with a simple policy tip or notification, overlooking that the 'BlockAccess' action combined with a threshold count (10) means the email is blocked, not just flagged, and that the rule is scoped to Exchange, not SharePoint.

Detailed technical explanation

How to think about this question

Under the hood, Microsoft Purview DLP uses sensitive information types (SITs) like 'Credit Card Number' with a confidence level (e.g., 'HighConfidence') that combines pattern matching and proximity checks. The 'Count' parameter in the condition evaluates the number of unique instances of the SIT in the email body or attachments; the 'BlockAccess' action triggers a transport rule in Exchange Online that rejects the message at the SMTP level, returning a non-delivery report (NDR) to the sender. In a real-world scenario, this prevents accidental mass exposure of credit card data in bulk emails, such as a marketing list inadvertently containing customer payment details.

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 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.
