true or false: a GUI is more user-friendly and requires less knowledge of the underlying command structure that controls the system

GUI

access method : a physical management port used to access a device in order to provide maintenance, such as performing the initial configurations

console

secure shell (ssh)

Perfectly

allows access only to a limited number of basic monitoring commands

user exec mode

How well did you know this?

Perfectly

the user exec mode is identified by the cli prompt that ends with the - symbol

Perfectly

allows access to all commands and all features

privileged exec mode

privileged exec mode is identified by the cli promp that ends with the - symbol

Perfectly

indicator for global configuration mode

switch(config) #

Perfectly

used to configure console, ssh, telnet, or aux access

line configuration mode

Not at all

Perfectly

indicator for line configuration mode

switch(config-line) #

used to configure switch port or router interface

interface configuration mode

Perfectly

indicator for interface configuration mode

switch(config-if) #

How well did you know this?

Not at all

Perfectly

this is used to move from user exec mode to privilege exec mode

enable command

How well did you know this?

Not at all

Perfectly

this is used to move in and out of global configuration mode

configure terminal command

this is used to return to privilege exec mode

exit

this is used to move in and out of line configuration mode

line command followed by the management line type

used to return to global configuration mode from line configuration mode

exit

to move out of any subconfiguration mode to get back to global configuration mode, use the - command

exit

to return to privilege exec mode from any subconfiguration mode, use - command or key combination -

end, c trl + z

this is done to move directly from one subconfiguration mode to another

type desired subconfiguration mode command

the basic ios command structure

prompt - command - space - keyword or argument

this is a specific parametern defined in the operating system

keyword

this is not predefined; it is a value or variable defined by the user

argument

this indicates commands and keywords that you enter literally as shown

boldface

this indicates arguments for which you have to supply values

italic

this indicates an optional element

[x]

this indicates a required element

{x}

command that provides context-sensitive help that enables you to quickly find answers to command questions

this verifies that a valid command was entered by the user

command syntax check

true or false: the configure command can be shortened to conf because configure is the only command that begins with conf

true

this completes a partial command name entry

tab

this erases the character to the left of the cursor

backspace

this moves the cursor one character to the left

left arrow or ctrl+b

this moves the cursor one charatcer to the right

right arrow or ctrl+f

this recalls the commands in the history buffer, beginning with the most recent commands

up arrow or ctrl+p

whena command output produces more text than can be displayed in the terminal window the ios will display this prompt

--more--

this should be the first configuration command on any device

give it a unique hostname

how to give a device a hostname

- enter privilege exec mode - switch# configure terminal swittch(config)# hostname [hostname] [hostname](config)#

all networking devices should limit administrative access by securing privilege exec, user exec, and remote telnet access with -

passwords

all passowrds should be - and -

encrypted, legal notifications provided

how to configure password to secure exec mode access

configure terminal line console 0 password [password] login end

how to configure passwords to secure privilege exec mode access

configure terminal enable secret [password] exit

how to configure passwords to secure vty line access

configure terminal line vty 0 15 password [password] login end

this enables remote access using telnet or ssh to the devices.

vty lines

this is used to encrypt all plain text passwords

service password-encryption global config command

this is used to verify that passwords on a device are now encrypted

show running-config

this is important to warn unauthorized personnel from attempting to access a device

banner message

this is used to create a banner message of the day on a network device

banner motd # [message] #

the "#" in the command syntax is called the - . it is entered before and after a message

deliminating character

how to configure a banner message of the day

configure terminal banner motd # message #

these are the 2 file systems tha store the device configuration

suartup-config, running-config

this. is the saved configuration file that is stored in nvram. it contains all the commands that will be used by the device upon starrup or reboot. flash does not lose its contents when the device is powered off

startup-config

this is tored in random access memory. it reflects the current configuration. modifying a running configration affects the operation of a cisco device immediately.

running-config

to save changes made to the running configuration to the startup configuration file, use the - privilege exec mode command

startup-config

changes made to the running config can be changed using this. if the running-config has not yet been saved

reload command

true or false: the reload command does not have any effects to the network

false; it temporarily goes offline, causing downtime

if the undesired changes were saved to the startup-config, it may be necessary to clear all the configurations using the - comamnd in privilege exec mode

erase startup-config

how to save configurattion files to a text document

- open terminal emulation software - enable logging into the terminal software and assign a name and file location to save the log file - execute show running-config or show startup-config - display logging in the terminal software

this is the primary means of enabling devices to locate one another and establish end-to-end communication on the internet

ip addresses

the structure of an ipv4 address is called -

dotted decimal notation

dotted decimal notation in ipv4 addressing is represented by -

4 decimal numbers between 0 and 255

this is a 32-bit value that differentiates the network portion of the address from the host portion. coupled with the ipv4 address, it determines to which subnet the device is a member

ipv4 subnet mask

this is the ip address of the router that the host will use to access remote networks, including the internet

default gateway

these are 128 bits in length and written as a string of hexadecimal values. every 4 bits is represented by a single hexadecimal digit for a total of 32 hexadecimal values

ipv6 adresses

true or false: ipv6 addresses are case sensitive

false
