Ethernet
The most common LAN type in the world
A: What is Ethernet?
The destination MAC address of the Ethernet frame as it leaves the PC if the final destination is a web server on another network
A: What is Default Gateway (Router’s interface)?
Action when a switch receives a frame with the destination MAC address FF:FF:FF:FF:FF:FF
A: What is The switch forwards it out all ports except the ingress port?
Two examples of the cut-through switching method
A: What are Fast-forward switching and Fragment-free?
A feature that automatically configures of an interface for a straight-through or a crossover Ethernet cable connection
A: What is the Auto-MDIX?
Field used to determine if errors occurred in the transmission and reception
A: What is Frame Check Sequence (FCS)?
Addresses used to build and maintain a MAC address table
Addresses used to build and maintain a MAC address table
Memory buffering method used in asymmetric switching (where frames are being exchanged between ports of different rates)
A: What is Shared Memory Buffering?
Switching method that has the lowest level of latency
A: What is Fast-Forward?
Switching method that uses the CRC value in a frame
A: What is Store-and-forward?
01-00-5E-00-00-03 is this type of address
A: What is Multicast MAC address?
Address used by the switch to forward frames
A: What is the Destination MAC address?
Action of a host when it receives a frame with a destination MAC address it does not recognize
A: What is The host will discard the frame?
Advantage of store-and-forward switching method compared with the cut-through switching method
A: What is Frame error checking?
One advantage of using the cut-through switching method instead of the store-and-forward switching method
A: What is It has a lower latency appropriate for high-performance computing applications?
Data link sublayer that is implemented in software and used to communicate with the upper layers of the protocol suite
A: What is the Logical Link Control (LLC)?
Action of a switch that receives a frame and does have the source MAC address in the MAC table
A: What is The switch refreshes the timer on that entry?
Action of a switch if it receives a frame with the destination MAC address 01:00:5E:00:00:D9
A: What is The switch forwards it out all ports except the ingress port?
Part of the Ethernet frame used to perform an error check
A: What is CRC in the trailer?
Results of connecting two modern, never been configured switches using a straight-through cable
A: What are The link between the switches will work at the fastest speed that is supported by both switches, The link between switches will work as full-duplex, and The auto-MDIX feature will configure the interfaces eliminating the need for a crossover cable?
Action of a Cisco Ethernet switch when it receives a runt frame
A: What is The frame is dropped?
Two potential network problems resulting from Mac Table
A: What are Multiple broadcasts can cause communication delays and Network hackers could manipulate the Mac Table mapping resulting in the interception of data?
Action of a host when it receives a frame with a destination MAC address of FF:FF:FF:FF:FF:FF
A: What is The host will process the frame?
Three characteristics of the cut-through switching method
A: What are It forward frames after receiving the destination address field, Less latency than a store-and-forward and Could transmit a corrupt or runt frame?
Three characteristics of store-and-forward switching method
A: What are Always stores the entire frame before forwarding, Checks its CRC to detect errors and Checks its frame length?
