Module Quiz 2

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

a switches creates many smaller collision domains and hub increases the size of a single collision domain

Which switching method makes use of the FCS value?

store-and-forward

Which option correctly describes a switching method?

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

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

the number of available ports

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 duplex increases the effective bandwidth

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

- the source MAC address and the incoming port

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

Switch

What is the purpose of frame buffers on a switch?

They hold traffic, thus alleviating network congestion.

Which statement is true about broadcast and collision domains?

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

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 of 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 buffering

Which network device can serve as a boundary to divide a Layer 2 broadcast domain?

router

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

source MAC address
