Which ordering is used when ACLs are evaluated?

• A. most specific to most generic
• B. most generic to most specific
• C. alphabetically by name
• D. random order

Answer: (A)

ACLs are evaluated from most specific to most generic. This means rules that target a very narrow scenario—such as a specific field on a particular table, or a table condition—are checked first, before broader rules that apply to larger sets of records. The reason this order is used is to give narrowly defined permissions priority, so precise restrictions can override more general ones and prevent unintended access. In practice, if a more specific rule applies to the access request, it will determine the outcome; only if no specific rule matches does the evaluation proceed to less specific rules, and if none apply, access is denied by default.
