The correct answer is VTY.

Telnet
Pinging a server just checks that Particular system is present on the network. Telnet or SSH are application to login the server from remote and use the services provided by the server. In TELNET DATA is not encrypted so it's easy to hack. In SSH DATA is encrypted so it's safe.
Windows: Open start menu, click "Run", type in "telnet" Linux: Open a Terminal window, type in "telnet"

SSH is more secure than Telnet.
If you want better security, use secure shell (ssh) instead of telnet. Actually, don't use telnet at all if possible, as it transmits all information in plain text.
Telnet is a Network layer protocol. It is used to create connection remotely.
