What is the minimum size of an Ethernet frame?
|
The minimum size of an Ethernet frame is 64 bytes.
|
|
|
Which part of the frame contains information used for checking the validity of the frame?
|
The frame check sequence (FCS) contains error-checking information.
|
|
|
Which device enables you to connect two networks, and discards broadcast traffic.
|
Routers connect networks, and discard broadcast traffic.
|
|
|
At which layer of the OSI model do traditional switches work.
|
Switches work at layer2, the Data link layer, because they manage traffic using MAC addresses.
|
|
|
At which layer of the OSI model don't multilayer switches work?
|
Multilayer switches can operate at any layer above layer 1.
|
|
|
Which protocol resolves switching loops?
|
Spanning Tree Protocol (STP) prevents switching loops from forming.
|
|
|
At which layer of the OSI model do routers work?
|
Routers work at layer 3, connecting different networks together.
|
|
|
How are the connectors wired on a crossover cable?
|
A properly wired crossover cable is T568A on one end and T568B on the other. All T568A or all T568B defines a straight-through cable Rj45 is for the UTP; RG-6 is for coaxial. You wouldn't find them on the same cable.

|
|
What feature of switches prevents the problem of switching loops?
|
Spanning Tree Protocol (STP) prevents switching loops. STP also stands for shielded twisted-pair; knowing the context in which the acronym is being used is important.
|
|
|
What feature of switches keeps track of which MAC address goes to each port?
|
A switch keeps track of which MAC address goes to each port with its source address table (SAT).
