Which of the following options can be used to only allow inbound SSH access to the vty lines of a router? (Choose two.)
- line vty 0 4
transport output ssh - line vty 0 4
transport input all - line vty 0 4
transport input ssh - ip access-list extended SSH
permit tcp any any eq 22
line vty 0 4
access-class SSH in
Explanation: Using the command transport input ssh and applying an ACL to the line that only allows port 22 are valid options to allow only SSH traffic into the line. The other two options are not valid because the command transport output ssh does not affect inbound connections, and the command transport input all allows all inbound SSH and Telnet sessions.
