Which data category is used only within the organization and includes personnel records?

• A. Private Data
• B. Public Data
• C. Confidential Data
• D. Unclassified (Military/Government)

Answer: (A)

Data classification is about restricting access based on sensitivity and need-to-know. Personnel records contain sensitive personal information, payroll details, and performance data, so they’re meant to stay inside the organization and be accessed only by authorized staff such as HR or management. That fits the category designed for internal use with restricted access, often labeled as Private Data.

Public Data is intended for open sharing, so it wouldn’t cover internal personnel files. Confidential Data is highly sensitive and may be shared with specific trusted parties under controls, not strictly limited to internal use. Unclassified (Military/Government) is a government labeling not typically applied to corporate personnel files.
