Why each option
This question asks for the command required to enable SSH or Telnet access on VTY lines of a Cisco switch.
`transport type all` is not a valid or standard command for configuring VTY line protocols.
`transport output all` would relate to outgoing connections from the VTY line, which is not what is required for remote access to the switch.
`transport preferred all` is not a valid or standard command for configuring VTY line protocols.
The `transport input all` command, applied within the VTY line configuration, enables all supported incoming protocols, including SSH and Telnet, for remote access to the Cisco switch.
Concept tested: Cisco VTY line configuration (transport input)
