If a system blocks data movement based on classification levels, which feature is being used?

• A. Dictionary
• B. Quarantine
• C. RDP Blocking
• D. Classification-Based Data Blocking

Answer: (D)

Data movement is governed by data loss prevention policies that use data classifications to control where information can go. When data is labeled with a classification level (such as confidential or restricted), a policy can block its transfer to destinations or channels that aren’t permitted for that level. This approach—enforcing actions based on the data’s classification label—is classification-based data blocking. It’s a data-centric security measure that stops sensitive information from leaving the environment according to the policy.

The other options don’t fit this scenario: a dictionary approach relies on matching terms inside content, not on predefined classification labels; quarantine isolates items after detection but doesn’t enforce blocking based on classification levels; and blocking RDP stops a type of network traffic rather than enforcing data movement rules based on data classification.
