What ISP connection type should be used? - DSL A company is expanding its business to other countries. All branch offices must remain connected to corporate headquarters at all times. Which network technology is required to support this requirement? - WAN Refer to the exhibit. From which location did this router load the IOS? - flash memory Which connection provides a secure CLI session with encryption to a Cisco network device? - an SSH connection Refer to the exhibit. An administrator is trying to configure the switch but receives the error message that is displayed in the exhibit. What is the problem? - The administrator must first enter privileged EXEC mode before issuing the command. An administrator uses the Ctrl-Shift-6 key combination on a switch after issuing the ping command. What is the purpose of using these keystrokes? - to interrupt the ping process What function does pressing the Tab key have when entering a command in IOS? - It completes the remainder of a partially typed word in a command.

Switch(config) # hostname My Switch - Switch(config)#? Refer to the exhibit. A network administrator is configuring access control to switch SW1. If the administrator uses Telnet to connect to the switch, which password is needed to access user EXEC mode? - linevtyin After making configuration changes, a network administrator issues a copy running-config startup-config command in a Cisco switch. What is the result of issuing this command? - The new configuration will be loaded if the switch is restarted. Refer to the exhibit.
