Which Hit Policy allows more than one hit, but limits the result to the output with the highest preference?

  15% (5)

Explanation

Priority hit policy allows multiple rules to fire simultaneously but returns only the single output value ranked highest according to a predefined output priority order - making it the only policy that combines "multiple hits allowed" with "preference-based selection."

Why the distractors are wrong:

• A (First): Returns the first matching rule in listed order - not preference-based, and stops at the first hit rather than evaluating all rules.
• B (Any): Allows multiple hits but requires all matching rules to produce the same output - no preference selection involved.
• C (Unique): Only one rule may match at all; overlapping rules are a modeling error under this policy.

Memory tip: Think of Priority as a Podium - multiple competitors (rules) can qualify, but only the gold medalist (highest-preference output) is announced.
