Which scenario would cause an ACL misconfiguration and deny all traffic?
- Apply a standard ACL using the ip access-group out command.
- Apply an ACL that has all deny ACE statements.
- Apply a standard ACL in the inbound direction.
- Apply a named ACL to a VTY line.
Explanation: Having all ACEs with deny statements denies all traffic because there is an implicit deny any command at the end of every standard ACL.
