After making configuration changes on a Cisco switch, a network administrator issues a copy running-config startup-config command. What is the result of issuing this command?
The new configuration will be stored in flash memory.

How is SSH different from Telnet?
SSH requires the use of the PuTTY terminal emulation program. Tera Term must be used to connect to devices through the use of Telnet.
SSH must be configured over an active network connection, whereas Telnet is used to connect to a device from a console connection.
SSH provides security to remote sessions by encrypting messages and using user authentication. Telnet is considered insecure and sends messages in plaintext.
SSH makes connections over the network, whereas Telnet is for out-of-band access.
SSH provides security to remote sessions by encrypting messages and using user authentication. Telnet is considered insecure and sends messages in plaintext.
