The correct answer is to block top secret content and allow confidential content with an override requiring a business justification. This configuration directly aligns with the firm’s data classification policy by treating ‘Legal Strategy’ as non-negotiable—DLP rules block it outright—while permitting ‘Client Contact Info’ to be sent, but only after the attorney provides a business justification override, a feature Microsoft 365 DLP supports through policy tips. On the CompTIA SecurityX CAS-004 exam, this scenario tests your ability to map DLP actions to data sensitivity levels and understand override mechanisms, a common trap being the temptation to block all sensitive data, which would break operational workflows. Remember the mnemonic “Block the crown, justify the rest”—top-secret data is the crown jewels, never to leave, while confidential data can be released with a documented reason.
CAS-004 Governance, Risk and Compliance Practice Question
This CAS-004 practice question tests your understanding of governance, risk and compliance. 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.
You are a security consultant for a law firm that handles highly confidential client data. The firm wants to implement a data loss prevention (DLP) solution to prevent sensitive data from leaving the network via email. The firm's email system is Microsoft 365. The DLP policy must comply with the firm's data classification policy, which identifies 'Legal Strategy' as top secret and 'Client Contact Info' as confidential. The firm also wants to allow attorneys to send confidential information to clients with a business justification. Which of the following DLP rule configurations best meets these requirements?

Correct answer & explanation
✓
Block top secret content and allow confidential content with an override requiring a business justification
Option D is correct because it aligns with the firm's data classification policy by blocking top-secret 'Legal Strategy' content outright, while allowing 'Client Contact Info' (confidential) to be sent with a business justification override. This balances security with operational needs, as Microsoft 365 DLP supports policy tips and override options with justification for lower-sensitivity data, ensuring compliance without disrupting attorney-client communication.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'allow with audit log' (passive monitoring) with 'allow with override requiring justification' (active enforcement), overlooking the specific business requirement for a justification workflow.
Detailed technical explanation
How to think about this question
Microsoft 365 DLP uses conditions (e.g., sensitive info types like 'U.S. Social Security Number' or custom regex) and actions (e.g., block, notify, override). The 'override with business justification' feature leverages policy tips in Outlook, where users can select a reason from a predefined list or type a custom justification, which is then logged in the audit log for compliance review. This granular control is essential for law firms to meet regulatory requirements like ABA Model Rules on confidentiality while enabling necessary data sharing.

Real-world example
How this comes up in practice
A practitioner preparing for the CAS-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
