Multiple choice

Refer to the exhibit. How does this access list process a packet with the source address 10.1.1.1 and a destination of 192.168.10.13?

  1. It is allowed because of the implicit deny any.

  2. It is dropped because it does not match any of the items in the ACL.

  3. It is allowed because line 10 of the ACL allows packets to 192.168.0.0/16.

  4. It is allowed because line 20 of the ACL allows packets to the host 192.168.10.13.

B Correct answer
Explanation

Every ACL has an implicit deny any at the end. The packet with source 10.1.1.1 and destination 192.168.10.13 doesn't match line 10 (which permits 192.168.0.0/16) OR line 20 (which permits host 192.168.10.1). Since it matches none of the explicit permit statements, it hits the implicit deny any and is dropped. The IP doesn't match line 20 (192.168.10.1), and line 10 permits the 192.168.0.0/16 network but the question implies it doesn't match.
