The answer is to modify the rule and set 'Allow override' to 'No' in the policy tip configuration. This setting directly controls whether users can bypass a DLP block action by submitting a business justification, so disabling it ensures the block on Social Security Numbers is enforced without exception. On the SC-900 exam, this question tests your understanding of Microsoft Purview DLP policy tip mechanics, specifically how to prevent override in Microsoft Purview DLP policy when sensitive data like SSNs must be strictly blocked. A common trap is confusing this with disabling policy tips entirely or changing the action from block to audit; however, the override permission is a separate toggle within the rule’s policy tip settings. For the exam, remember that the "Allow override" toggle is the gatekeeper for user bypass—flip it to "No" to lock the gate. A helpful memory tip: "No override, no excuse—SSNs stay inside the noose."
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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
You are a security administrator for a company that uses Microsoft 365. The company has a Microsoft Purview Data Loss Prevention (DLP) policy that blocks sharing of Social Security Numbers (SSNs) externally. Recently, a user accidentally sent an email containing SSNs to an external partner after overriding the policy by selecting a business justification. Management wants to prevent users from overriding the policy for SSNs. You need to update the DLP policy to ensure that users cannot override the block for SSNs. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Modify the rule to set 'Allow override' to 'No' in the policy tip configuration.
Option A is correct because the 'Allow override' setting in the policy tip configuration directly controls whether users can bypass a DLP block action by providing a business justification. Setting this to 'No' prevents any override for the rule that blocks SSNs, ensuring that the block is enforced without exception. This is the specific mechanism in Microsoft Purview DLP to disable user overrides for a given rule.
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.
✓
Modify the rule to set 'Allow override' to 'No' in the policy tip configuration.
Why this is correct
This disables the override option while keeping the policy tip.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the rule priority to ensure it is enforced before other rules.
Why it's wrong here
Priority does not affect override capability.
✗
Remove the policy tip from the rule to prevent users from overriding.
Why it's wrong here
Removing the policy tip does not prevent override; users might still override via other means.
✗
Change the action from 'Block with override' to 'Block' and remove the policy tip.
Why it's wrong here
This prevents override but also removes user notification, which may not be desired.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think removing the policy tip or changing the action to 'Block' is necessary, but the correct approach is to keep the policy tip and disable the override setting, which is a subtle but distinct configuration in the DLP rule properties.
Detailed technical explanation
How to think about this question
In Microsoft Purview DLP, the 'Block with override' action allows users to bypass the block by selecting a business justification from the policy tip. The 'Allow override' setting is a per-rule toggle that, when set to 'No', converts the action to a hard block without removing the policy tip. This ensures users still see the warning but cannot proceed, which is critical for compliance with regulations like GDPR or HIPAA where override must be prohibited for sensitive data types like SSNs.

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.
