Internetwork 2 quiz

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

The number of available ports

A switch use to keep the MAC address table information current

The source MAC address and the incoming port

The purpose of frame buffers on a switch

They hold traffic, thus alleviating network congestion

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

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

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 all ports except the port where the frame is received

Characteristic helps alleviate network congestion when a 10 Gbps port is forwarding data to a 1 Gbps port

Frame buffering

Two statements are true about half-duplex and full-duplex communications

Full duplex allows both ends to transmit and receive Full duplex increases the effective bandwidth

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

Source MAC address

Switching method makes use of the FCS value

Store-and-forward

Option correctly describes a switching method?

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

Type of network device can be used to eliminate collisions on an Ethernet network

Switch

Network device can serve as a boundary to divide a Layer 2 broadcast domain
