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

Frame buffering

A __________ can serve as a boundary to divide layer 2 broadcast domain.

router

Which switching method makes use of the FCS value?

store-and-forward

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?

100Mbps

Which device separates broadcast domains?

Access point

Which statement is correct about Ethernet switch frame forwarding decisions?

Frame forwarding decisions are based on MAC address and port mappings in the CAM table.

Which characteristic describes cut-through switching?

Frames are forwarded without any error checking.

Which two statements are true about broadcast and collision domains?

Adding a layer 2 switch to a network will increase the size of the broadcast domain A interfaces in a layer 2 switch limit collision 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 internal switching ?

Match the following term with their contribution to alleviate network congestion:

Fast port speeds - ethernet switch port speeds... Fast internal switching - Switches use a fast... Large frame buffers - enables ingress traffic... High port density - high port density...

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

The source MAC address and the incoming port

A switch receives a layer 2 frame that contains a source MAC address 0060.cafe.0010 and destination MAC address 0060.cafe.0005. Place the switch's steps in the order they occur.

The switch adds the source... Because the destination is....

What is the purpose of frame buffers on a switch?

To hold traffic and alleviate network congestion
