ICTN 2150 FINAL EXAM VERIFIED STUDY GUIDE
Intermediary Devices - Answers - Interconnects end devices. Includes switches,
wireless access points, routers, and firewalls.
-Regenerate and retransmit data signals
-Maintain information about what pathways exist in the network
-Notify other devices of errors and communication failures
Topology - Answers - Network diagrams, use symbols to represent devices within the
network.
-Physical- illustrate the physical location of intermediary devices and cable installation
-Logical- illustrate devices, ports, and the addressing scheme of the network
LAN - Answers - -Small geographical area
-Interconnect end devices in a limited area
-Administered by a single organization or individual
-Provide high-speed bandwidth to internal devices
WAN - Answers - -Spans a wide geographical area
-Interconnect LANs over wide geographical areas
-Typically administered by one or more service providers
-Typically provide slower speed links between LANs
Point-to-point- the simplest and most common WAN topology
Quality of Service (QoS) - Answers - Primary mechanism used to ensure reliable
delivery of content for all users. With a QoS policy in place, the router can more easily
manage the flow of data and voice traffic
Cloud Computing - Answers - Allows us to store personal files or backup our data on
servers over the internet
Shell - Answers - User interface that allows users to request specific tasks from the
computer through the CLI or GUI interfaces
Kernel - Answers - Communicates between the hardware and software of a computer
and manages how hardware resources are used to meet software requirements
Hardware - Answers - Physical part of a computer including underlying electronics
GUI - Answers - Allows the user to interact with the system using an environment of
graphical icons, menus, and windows
Console - Answers - Physical management port used to access a device in order to
provide maintenance, such as initial configurations
, Secure Shell (SSH) - Answers - Establishes a secure remote CLI connection to a
device, through a virtual interface, over a network
Telnet - Answers - Establishes an insecure remote CLI connection to a device over the
network
Primary Command Modes - Answers - User EXEC >
Privileged EXEC #
Global Configuration (config)#
Line Configuration (config-line)#
Startup-config - Answers - Stored in NVRAM, contains all the commands that will be
used by the device upon the startup or reboot
Running-config - Answers - Stored in RAM, reflects the current configuration. Loses all
of it's content when the device is powered off or restarted
IPv6 Addresses - Answers - 128 bits in length and written as a string of hexadecimal.
Flow control - Answers - Manages the rate of data transmission and defines how much
information can be sent and the speed at which it can be delivered
Segmenting - Answers - Process of breaking up messages into smaller units.
Multiplexing is the process of taking multiple steams of segmented data and interleaving
them together.
Protocol Suites - Answers - A group of inter-related protocols necessary to perform a
communication function.
-TCP/IP
-OSI
-AppleTalk
Encapsulation - Answers - Process where protocols add their information to the data.
Top-down process
Source IP address - Answers - The IP address of the sending device, original source of
the packet
Destination IP address - Answers - The IP address of the receiving device, final
destination of the packet
Default Gateway (DGW) - Answers - Is the router interface IP address that is part of this
LAN and will be the "door" or "gateway" to all other remote locations
