Which of the following is a prerequisite for a DLP solution?

Data classification is required before implementing a Data Loss Prevention (DLP) solution because DLP policies depend on identifying and categorizing sensitive data to monitor, block, or encrypt it accordingly.

Data destruction (A) and sanitization (B) remove data, and masking (D) obscures data but classification is foundational for DLP effectiveness.

Data classification is emphasized in Security Program Management and Data Protection topics【6:Chapter 16†CompTIA Security+ Study Guide】.
