What can be done to secure the virtual terminal interfaces on a router? (Choose two.)

A.
Administratively shut down the interface.

B.
Physically secure the interface.

C.
Create an access list and apply it to the virtual terminal interfaces with the access-group
command.

D.
Configure a virtual terminal password and login process.

E.
Enter an access list and apply it to the virtual terminal interfaces using the access-class command.

Explanation:
It is a waste to administratively shut down the interface. Moreover, someone can still access the
virtual terminal interfaces via other interfaces -> A is not correct. We can not physically secure a
virtual interface because it is “virtual” -> B is not correct. To apply an access list to a virtual terminal
interface we must use the “access-class” command. The “access-group” command is only used to
apply an access list to a physical interface -> C is not correct; E is correct. The most simple way to
secure the virtual terminal interface is to configure a username & password to prevent unauthorized
login -> D is correct.
