ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 19

Which command is necessary to permit SSH or Telnet access to a Cisco switch that is otherwise configured for these vty line protocols?

Answer options

• A. transport output all
• B. transport preferred all
• C. transport type all
• D. transport input all D

Correct answer:

Explanation

The correct answer is D, 'transport input all', as it specifies which protocols are allowed for incoming connections on the vty lines. The other options are incorrect because 'transport output' and 'transport preferred' do not pertain to configuring incoming access, and 'transport type' is not a valid command in this context.
