Protecting Sensitive Data with DLP and Classification
Short answer
C Configure Data Loss Prevention (DLP) to enforce policies based on the organization's existing data labeling and classification system to protect sensitive information.
Question
Key Takeaways
This tests knowledge of data protection mechanisms, specifically how DLP integrates with data classification to prevent unauthorized exposure or loss of sensitive information like PII/PHI.
The question asks for a security measure to protect sensitive data using existing labeling systems. Data Loss Prevention (DLP) is the correct technology as it enforces policies based on data classification labels.
Common mistake: Candidates often confuse DLP with encryption tools like S/MIME. While S/MIME protects data in transit via email, it does not enforce organizational labeling policies across all data types or locations.
Expert Analysis
Why the Answer Is Correct
Data Loss Prevention (DLP) solutions are designed to monitor, detect, and block sensitive data from leaving the corporate network. A core feature of modern DLP systems is their ability to integrate with data classification and labeling frameworks. By reading these labels, the DLP engine can apply specific policies (e.g., 'Do not allow PHI to be emailed externally') automatically, meeting the requirement to use the organization's existing system.
Why the Other Options Are Wrong
Tokenization (A) replaces sensitive data with non-sensitive equivalents but doesn't inherently use classification labels for policy enforcement across the environment. S/MIME (B) provides encryption and authentication for emails specifically, not general data protection based on labels. MFA (D) controls access to resources but does not inspect content or enforce data handling policies based on classification.
Community Comment Notes
The community consensus strongly supports C. Many users noted that "PH" is likely a typo for PHI (Protected Health Information) or PII, which are common targets for DLP. As one user paraphrased, DLP prevents data from being lost or stolen by leveraging these classifications.
Exam Strategy
When you see keywords like 'labeling', 'classification', and 'protect data' together, think DLP. Encryption and Access Control manage confidentiality and access, while DLP manages the movement and usage of classified data.

[Removed] 👍 14 Answered CI think that the PH is an error and is supposed to be PHI. DLP prevents people from sending information about PII and PHI and pretects againts data loss. i can see any of the other question fitting.

Hs1208 👍 3 Answered CC. DLP (Data Loss Prevention) Data Loss Prevention (DLP) is the security measure that would most likely be configured to meet the requirements of protecting Personally Identifiable Information (PII) while using the organization's existing labeling and classification system.

scoobysnack209 👍 1You guys are right, it might be a type since 'PH' in not in the Security+ acronym list.
