How is SSH different from Telnet?

• 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.

• 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.

What are three characteristics of an SVI? (Choose three.)

• It is associated with VLAN1 by default.

• It provides a means to remotely manage a switch.

• It is a special interface that allows connectivity by different types of media.

• It is not associated with any physical interface on a switch.

• It is designed as a security protocol to protect switch ports.

What command is used to verify the condition of the switch interfaces, including the status of the interfaces and a configured IP address?

• ipconfig

• ping

• traceroute

• show ip interface brief
