v1 CLI Commands
Which CLI command will change the host name?
a. Router(config)# hostname CL1
b. Router(config)# enable password Cisco
c. Router(config)# banner motd #
what is
a. Router(config)# hostname CL1
A router boots and enters setup mode. What is the reason for this?
a. The IOS image is corrupt.
b. Cisco IOS is missing from flash memory.
c. The configuration file is missing from NVRAM.
what is
c. The configuration file is missing from NVRAM.
If a router cannot locate the startup-config file in NVRAM, it will enter setup mode to allow the configuration to be entered from the console device.

Which command do you need to create a banner message?
a. Router(config)# hostname CL1
b. Router(config)# banner motd #
c. Router(config)# password Cisco
what is
b. Router(config)# banner motd #
What happens when the transport input ssh command is entered on the switch vty lines?
a. The SSH client on the switch is enabled.
b. Communication between the switch and remote users is encrypted.
c. The switch requires a username/password combination for remote access.
what is
b. Communication between the switch and remote users is encrypted.
The transport input ssh command when entered on the switch vty (virtual terminal lines) will encrypt all inbound controlled telnet connections.
A new network administrator has been asked to enter a banner message on a Cisco device. What is the fastest way a network administrator could test whether the banner is properly configured?
a. Exit global configuration mode.
b. Power cycle the device.
c. Exit privileged EXEC mode and press Enter .
what is
c. Exit privileged EXEC mode and press Enter .
While at the privileged mode prompt such as Router#, type exit ,press Enter , and the banner message appears. Power cycling a network device that has had the banner motd command issued will also display the banner message, but this is not a quick way to test the configuration.

10.1 Configure Initial Router Settings
What are two functions of NVRAM? (Choose two.)
a. to store the routing table
b. to retain contents when power is removed
c. to store the startup configuration file
d. to contain the running configuration file
what is
b. to retain contents when power is removed
c. to store the startup configuration file
NVRAM is permanent memory storage, so the startup configuration file is preserved even if the router loses power.
The global configuration command ip default-gateway 172.16.100.1 is applied to a switch. What is the effect of this command?
a. The switch can be remotely managed from a host on another network.
b. The switch can communicate with other hosts on the 172.16.100.0 network.
c. The switch is limited to sending and receiving frames to and from the gateway 172.16.100.1.
what is
a. The switch can be remotely managed from a host on another network.
The switch can be remotely managed from a host on another network.
True or False. These 3 commands are used to set up secure access to a router through a connection to the console interface?
line console 0
login
password cisco
what is
true
The three commands needed to password protect the console port are as follows:
line console 0
password cisco
login
The interface fastethernet 0/0 command is commonly used to access the configuration mode used to apply specific parameters such as the IP address to the Fa0/0 port. The line vty 0 4 command is used to access the configuration mode for Telnet. The 0 and 4 parameters specify ports 0 through 4, or a maximum of five simultaneous Telnet connections. The enable secret command is used to apply a password used on the router to access the privileged mode.
What is entered when at R1>
a. enable
b. login
c. copy running-config startup-config
what is
a. enable
What will happen if the default gateway address is incorrectly configured on a host?
a. The host cannot communicate with other hosts in the local network.
b. The switch will not forward packets initiated by the host.
c. The host will have to use ARP to determine the correct address of the default gateway.
d. The host cannot communicate with hosts in other networks.
what is
d. The host cannot communicate with hosts in other networks.
When a host needs to send a message to another host located on the same network, it can forward the message directly. However, when a host needs to send a message to a remote network, it must use the router, also known as the default gateway. This is because the data link frame address of the remote destination host cannot be used directly. Instead, the IP packet has to be sent to the router (default gateway) and the router will forward the packet toward its destination. Therefore, if the default gateway is incorrectly configured, the host can communicate with other hosts on the same network, but not with hosts on remote networks.
