This SC-900 practice question tests your understanding of describe the capabilities of microsoft security 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.
Your organization uses Microsoft Purview Data Loss Prevention (DLP) to protect sensitive data. You need to prevent users from sharing credit card numbers in emails to external recipients. Which DLP rule action should you configure?
Audit the activity only
Why wrong: Auditing only logs the activity, does not block it.
Allow the message but notify the user
Why wrong: Allowing with notification does not prevent sharing.
Block the message from being sent
Blocking the message prevents data loss by stopping the email from being sent.
Allow the message with a policy tip
Why wrong: Policy tips provide guidance but do not block the email.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Block the message from being sent
Option A is correct because blocking the message from being sent is the appropriate action to prevent data loss. Option B is wrong because allowing override with justification does not prevent sharing. Option C is wrong because notifying the user without blocking still allows the email to be sent. Option D is wrong because auditing alone does not block the action.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
