question 15
a network administrator establishes a connection to a switch via ssh. what characteristic uniquely describes the ssh connection?
out - of - band access to a switch through the use of a virtual terminal with password authentication
remote access to a switch where data is encrypted during the session
direct access to the switch through the use of a terminal emulation program
remote access to the switch through the use of a telephone dialup connection
on - site access to a switch through the use of a directly connected pc and a console cable

Explanation:

SSH (Secure Shell) is a network protocol that provides a secure way to access a remote device. It encrypts the data transmitted during the session, which is a key characteristic. Out - of - band access (e.g., using a modem for dial - up) is not related to SSH. Direct access via a terminal emulation program (like using a console cable) is not SSH. On - site access with a directly connected PC and console cable is local access, not SSH. And using a telephone dialup connection is a different form of out - of - band or remote access (but not SSH).

Answer:

Remote access to a switch where data is encrypted during the session.
