Which protocols use encryption to protect the confidentiality of data transmitted between two parties? (Choose two.)
A . FTP
B . SSH
C . Telnet
D . AAA
E . HTTPS
F . HTTP
Answer: B,E
Explanation:
+ Secure Shell (SSH) provides the same functionality as Telnet, in that it gives you a CLI to a router or switch; unlike Telnet, however, SSH encrypts all the packets that are used in the session.
+ For graphical user interface (GUI) management tools such as CCP, use HTTPS rather than HTTP because, like SSH, it encrypts the session, which provides confidentiality for the packets in that session.
