The answer is that the DLP policy for Teams is only applied when external users are part of the chat. This occurs because Microsoft Purview Data Loss Prevention (DLP) for Teams chat messages is designed to scan and block sensitive data like credit card numbers only when at least one participant is from outside the organization; internal-only chats are not evaluated by the policy, even if the policy is correctly configured and enabled. On the MS-102 exam, this tests your understanding of the scope limitations of Teams DLP, a common trap where candidates assume all chat traffic is covered equally. A reliable memory tip is “external triggers the block”—if everyone is internal, the DLP policy simply does not fire, so credit card numbers flow freely without any block.

Correct answer & explanation
✓
