Which device separates broadcast domains?

router

What is the significant difference between a hub and a Layer 2 LAN switch?

a switch creates many smaller collision domains, and a hub increases the size of a single collison domain

What is one function of a Layer 2 switch?

determines which interface is used to forward a frame based on the destination MAC address

Which two special characteristics do LAN switches use to alleviate network congestion? (Choose two.)

fast port speeds fast internal switching

Which type of address does a switch use to build the MAC address table?

source mac address

Which option correctly describes a switching method?

store and forward:ensures that the frame is free of physical and data link errors

Which switching method makes use of the FCS value?

store-and forward

What does the term "port density" represent for an Ethernet switch?

the number of available ports

Which network device can be used to eliminate collisions on an Ethernet network?

switch

Which port speed will be autonegotiated between a host with a 1 Gbps NIC connecting to a Cisco Catalyst 2960 switch with a 100 Mbps port?

100 Mbps

Which statement is true about broadcast and collision domains?

adding a switch to the network will increase the size of the broadcast domain

Which two statements are true about half-duplex and full-duplex communications? (Choose two.)

full duplex allows both ends to transmit and receive simultaneously full deplex increases the effective bandwidth

What will a Cisco LAN switch do if it receives an incoming frame and the destination MAC address is not listed in the MAC address table?

forward the frame out all ports except the port where the frame is received

Which switch characteristic helps alleviate network congestion when a 10 Gbps port is forwarding data to a 1 Gbps port?

frame buggering

Which information does a switch use to keep the MAC address table information current?

the source mac address and the incoming port

What is the purpose of frame buffers on a switch?

they hold traffic, thus alleviating network congestion
