I'm using the exclusion method, and I'm going to say what I think. 1. B and D are definitely wrong, so we only have options A and C. 2. The option of C is reasonable, because the rule means that all source addresses are denied. 3. In some protocols, the default action of ACL rules is deny. 4. Both A and C are reasonable, but this question is a single choice.And this question I don't think is precise, I choose A based on personal feeling. |
