An inbound IPv4 ACL on a Cisco router has several permit and deny statements, and the show access-lists command displays no additional lines after the last explicit entry. How does the router handle any packet that reaches the end of the ACL without matching an entry?
Access Control Lists (ACLs) have an implicit "deny all" statement at the end. This means any packet that doesn't match one of the explicit permit or deny lines is automatically denied. Therefore, unmatched packets are dropped. The other options are wrong because ACLs do not permit unmatched traffic, forward it to another hop, or log it unless specifically configured to do so.
