Log file analysis on a router reveals several unsuccessful telnet attempts to the virtual terminal
(VTY) lines. Which of the following represents the BEST configuration used in order to prevent
unauthorized remote access while maintaining secure availability for legitimate users?
A.
Disable telnet access to the VTY lines, enable SHH access to the VTY lines with RSA
encryption
B.
Disable both telnet and SSH access to the VTY lines, requiring users to log in using HTTP
C.
Disable telnet access to the VTY lines, enable SHH access to the VTY lines with PSK
encryption
D.
Disable telnet access to the VTY lines, enable SSL access to the VTY lines with RSA
encryption
I believe this should be A. PSK is for wireless access point, RSA is used to set up VTY lines

1. It is clearly SSH. A is the best answer here. This is a cisco question and Cisco uses RSA generated keys for SSH as a staple.
