CCNA R&S Question of the Week: Secure Virtual Terminal Sessions

Answer: D and E.

Answer A is incorrect because the virtual terminal sessions are not tied to any specific interface, they are considered inband management, so any interface on a router can be used to access the router. Answer B is also incorrect because we cannot physically secure a virtual session because it is “virtual.”

Answer C is incorrect, and answer E is correct because to apply an access list to a virtual terminal session we must use the “access-class” command. The “access-group” command is only used to apply an access list to a physical interface.

Answer D is also correct because the simplest way to secure the virtual terminal session is to configure a password to prevent unauthorized login.
