| The portion that interfaces with applications and the user | Shell |
| The user can interact with the shell using a: | command-line interface (CLI) or a graphical user interface (GUI). |
| The physical part of a computer including underlying electronics. | Hardware |
| allows the user to interact with the system using an environment of graphical icons, menus, and windows | Graphical User Interface |
| The operating system on home routers | firmware |
| this is a physical management port that provides out-of-bound access to a Cisco device | Console |
| is an in-band and recommended method for remotely establishing a secure CLI connection | Secure Shell (SSH) |
| is an insecure, in band method of remotely establishing a CLI session | Telnet |
| Which access method would be most appropriate if you were in the equipment room with a new switch that needs to be configured? | Console |
| Which access method would be most appropriate if your manager gave you a special cable and told you to use it to configure the switch? | Console |
| Which access method would be the most appropriate in-band access to the IOS over a network connection? | Telnet/SSH |
| Which access method would be the most appropriate if you call your manager to tell him you cannot access your router in another city over the internet and he provides you with the information to access the router through a telephone connection? | Aux |
| This mode has limited capabilities but is useful for basic operations | User EXEC Mode |
| This mode allows access to all commands and features | Privileged EXEC Mode |
| is identified by a prompt that ends with (config)# after the device name, such as Switch(config)#. | Global Configuration Mode |
| Used to configure console, SSH, Telnet, or AUX access. | Line Configuration Mode |
| Used to configure a switch port or router network interface. | Interface Configuration Mode |
| the default prompt for line configuration mode | Switch(config-line)# |
| default prompt for interface configuration mode | Switch(config-if)# |
| used to move from user EXEC mode to privileged EXEC mode | enable command |
| used to return to user EXEC mode | disable privileged EXEC mode command |
| sometimes called enable mode. | Privileged EXEC mode |
| used to move in and out of global configuration mode, | configure terminal |
| used to return to the privileged EXEC mode | exit global config mode command |
| used to enter line subconfiguration mode | line command |
| used to exit a subconfiguration mode and return to global configuration mode. | exit command |
| used to move from any subconfiguration mode of the global configuration mode to the mode one step above it in the hierarchy of modes | exit command |
| used to move from any subconfiguration mode to the privileged EXEC mode | end command / ctrl + Z |
| has a specific format, or syntax, and can only be executed in the appropriate mode | IOS Command |
| This is a specific parameter defined in the operating system | keyword |
| This is not predefined; it is a value or variable defined by the user | argument |
| used to submit the command to the command interpreter. | enter key |
| provides the pattern, or format, that must be used when entering a command. | syntax |
| indicates commands and keywords that you enter literally as shown | Boldface text |
| indicates arguments for which you supply values | italics |
| indicate an optional element (keyword or argument) | [] / square brackets |
| indicates a required element (keyword or argument) | {} / braces |
| indicate a required choice within an optional element | [ { | } ] / braces and vertical lines within square brackets |
| is typically used to identify the purpose of an interface | description command |
| the user-defined argument is the ip-address of the destination device | ping command |
| just like ping command but has more information | traceroute command |
| enables you to quickly find answers | context-sensitive help |
| verifies that a valid commands was entered by the user | command syntax check |
| used To secure privileged EXEC access | enable secret command |
| enable remote access using Telnet or SSH to the device. | Virtual Terminal lines (VTY) |
| used To secure VTY lines | line vty 0 15 command |
| used specify the VTY password | password command |
| used to enable VTY access | login command |
| used to encrypt all plaintext passwords | service password-encryption command |
| used to verify that the passwords are now encrypted | show running-config command |
| used to create a banner message | banner motd # ~~ # command |
| entered before and after a massage | '#' / delimiting character |
| What is the command to assign the name “Sw-Floor-2” to a switch? | hostname Sw-Floor-2 |
| How is the privileged EXEC mode access secured on a switch? | enable secret class |
| Which command enables password authentication for user EXEC mode access on a switch? | login |
| Which command encrypts all plaintext passwords access on a switch? | service password-encryption |
| which command is used to set a banner | banner motd |
| This is the saved configuration file that is stored in NVRAM | startup-config |
| This is stored in Random Access Memory (RAM). | running-config |
| is used to view the running config | show running-config |
| To view the startup configuration file | show startup-config |
| to save changes made to the running configuration to the startup configuration file | copy running-config startup-config |
| used to remove the changed commands individually or reload the device | reload |
| is the primary means of enabling devices to locate one another and establish end-to-end communication on the internet. | ip address |
| has a structure called dotted decimal notation and is represented by four decimal numbers between 0 and 255 | IPv4 address |
| has 128 bits in length and written as a string of hexadecimal values | IPv6 address |
| an interface that has no physical port associated with it | Switch virtual interface (SVI) |
