What is the purpose of the service password-encryption command?
Encrypts passwords stored in the configuration file
Enables SSH on the device
Changes the device hostname
Assigns an IP address to the switch
Which of the following is a reason to use SSH instead of Telnet for remote access?
SSH uses less bandwidth
SSH provides encryption for security
SSH allows multiple users to connect at once
SSH is only available on Windows
What is the difference between the startup-config and running-config files?
The startup-config is stored in RAM, while the running-config is stored in NVRAM
The running-config is stored in RAM and is lost after a reboot, while the startup-config is stored in NVRAM
The running-config is only used during bootup, while the startup-config is used for live configuration changes
The startup-config can only be modified by privileged users
Which interface must be configured with an IP address to enable remote management of a switch?
FastEthernet0/1
GigabitEthernet0/1
VLAN 1
Console 0
