Explanation
In Network ACL rules, a lower numerical priority value means the rule is evaluated first, giving it higher precedence - so option C is correct. This convention is standard across many networking platforms (such as AWS and Huawei Cloud), where rule 1 is checked before rule 100, allowing administrators to place more specific or critical rules at lower numbers. Option A is wrong because the priority value directly determines evaluation order. Options B and D are inverses of the correct behavior - they both claim a larger value means higher priority, which is the opposite of how ACL rules work. Memory tip: think of priority values like race positions - first place (the lowest number) wins, meaning a smaller number gets processed first and holds the highest priority.
