Watch list matching is best described as a form of identification aimed at determining whether a person is a member of a predefined list.

• A. RBAC
• B. Watch list matching
• C. Group ID matching
• D. Group acceptance

Answer: (B)

Identification focuses on determining who a person is by comparing them to a known set of identities. Watch list matching embodies this by checking whether an individual's attributes match anyone on a predefined watch list. If a match is found, the person is flagged for further action; if not, they are not on the list. This is different from authentication, which asks someone to prove they are who they claim to be, and from role- or group-based access controls (like RBAC), which grant permissions based on a person’s assigned role or group rather than screening for membership in a specific list. Therefore, watch list matching is the best description because its purpose is to identify membership in a predefined set.
