Chapter 10 Flashcards
An IEEE standard mechanism (802.3u) with which two nodes can exchange messages for the purpose of choosing to use the same Ethernet standards on both ends of the link, ensuring that the link functions and functions well.
Autonegotiation
A set of all devices that receive broadcast frames originating from any device within the set.
Broadcast domain
An Ethernet frame sent to destination address FFFF.FFFF.FFFF, meaning that the frame should be delivered to all hosts on that LAN.
Broadcast frame
A set of network interface cards (NIC) for which a frame sent by one NIC could result in a collision with a frame sent by any other NIC in the same _____ _____.
Collision domain
The result of the LAN switch forwarding process for broadcasts and unknown unicast frames. Switches forward these frames out all interfaces, except the interface in which the frame arrived. Switches also flood multicasts by default, although this behavior can be changed.
Flooding
A group of devices, connected to one or more switches, with the devices grouped into a single broadcast domain through switch configuration. These allow switch administrators to separate the devices connected to the switches into separate _____ without requiring separate physical switches, gaining design advantages of separating the traffic without the expense of buying additional hardware.
Virtual LAN
A wireless LAN device that provides a means for wireless clients to send data to each other and to the rest of a wired network, with this device connecting to both the wireless LAN and the wired Ethernet LAN.
Access Point (AP)
A device that cooperates with wireless lightweight access points (LWAP) to create a wireless LAN by performing some control functions for each LWAP and forwarding data between each LWAP and the wired LAN.
Wireless LAN controller
A network topology in which endpoints on a network are connected to a common central device by point-to-point links.
Star topology
A network topology in which more than two devices can physically communicate and, by choice, all pairs of devices are allowed to communicate directly.
Full mesh
A network topology in which more than two devices could physically communicate but, by choice, only a subset of the pairs of devices connected to the network is allowed to communicate directly.
Partial mesh
A LAN device that provides a centralized connection point for LAN cabling, repeating any received electrical signal out all other ports, thereby creating a logical bus. These do not interpret the electrical signals as a frame of bits, so these devices are considered to be Layer 1 devices.
Hub
The name of a networking device that was a precursor to modern LAN switches. Bridges forward frames between LAN segments based on the destination MAC address.
Transparent bridge
A campus LAN design in which the design does not use a separate set of core switches in addition to the distribution switches.
Collapsed core design
A campus LAN design that connects each access switch to distribution switches, and distribution switches into core switches, to provide a path between all LAN devices.
Core design
In a campus LAN design, the switches that connect directly to endpoint devices (servers, user devices), and also connect into the distribution layer switches.
Access layer
In a campus LAN design, the switches that connect to access layer switches as the most efficient means to provide connectivity from the access layer into the other parts of the LAN.
Distribution layer
In a campus LAN design, the switches that connect the distribution layer switches, and to each other, to provide connectivity between the various distribution layer switches.
