what is the destination MAC address of a layer 2 broadcast
FF:FF:FF:FF:FF:FF
how many broadcast domains are there with a switch
one
how many collision domains are there with a switch
as many ports on the switch
what does CAM stand for
content addressable memory
how does a switch learn MAC addresses
a process called filtering
sends the message to all ports and learns the MAC addresses that way
what are the three types of frames that are flooded by a switch
broadcast
multicast
unknown unicast
what are the three primary forms of switch frame transmission
store and forward
fragment free
cut-through
which of the three forms of switch frame transmission is the fastest
cut-through
what is a cut-through switch frame transmission
Switch reads the destination MAC address and then immediately begins forwarding the frame.
what is a fragment free switch frame transmission
Switch will read the first 64 bytes before forwarding the frame.
what is a store and forward switch frame transmission
Switch must receive the entire frame before forwarding takes place.
what does FCS stand for
Frame Check Sequence (FCS)
what does CRC stand for
cyclic redundancy check (CRC)
what does switches use to provide their hardware based functions
Application Specific Integrated Circuitry (ASIC)
what does ASIC stand for
Application Specific Integrated Circuitry (ASIC)
what does MDI stand for
media dependent inerface
what are MDI ports often referred to as
uplink
what is the difference between an MDI port and an MDI-X port
MDI - not labeled, cross over
MDI-X - labeled , straight though
what type of cable would be used to interconnect two MDI-X ports
cross over cable
what type of cable would be used to interconnect two MDI ports
cross over cable
what type of cable would be used to interconnect an MDI port and an MDI-X port
straight through cable
what are the devices that use cross over cables
hub to switch
workstation to router
server to router
what is a collision domain
is a group of devices connected to the same physical media, such that if two devices access the media at the same time, the result is a collision of the two signals
how many collision domains are there with a hub
one
what communication mode must be used when communicating to a hub
half duplex communication mode
what is a broadcast domain
is a group of devices that will receive one anther's broadcast traffic
how many broadcasts domains are there with a hub
one
what is a manageable hub
provide a management console that allows the network administrator to manage and configure certain options
what is a stackable hub
can be linked together so that they operate as a single, larger hub
what is the purpose of media converter
are used to interconnect different types of cable within an existing network
what is the most important consideration when selecting network media converters
network type
what does IC stand for
integrated circuit
what does PCB stand for
printed circuit board
what type of media converter allows network administrators to monitor and configure network end points, thus ensuring maximum uptime of the network
