What reserved address is a local broadcast address?
The IP address 255.255.255.255 is reserved for local broadcast.
Host a sends a frame with the destination mac address as ffffffffffff what action will the switch take for this frame?
It will send the frame to all hosts except host A.This is a MAC broadcast address. All hosts on that subnet will receive the packet or frame. With the exception of the sending host of course.
What type of address is 202.23.2.255?
It is a broadcast address
What happens to the MAC address when you move a computer to another network?
The MAC address is a unique identifier for a networking card. Each networking card has a MAC address assigned to it during it's manufacturing, and thus it does not change when a computer moves between networks (unlike an IP address which is assigned by the network). A few things to note: - A computer only has a MAC address if it has a physical or virtual network card - A computer has as many MAC addresses as it has networking cards - MAC addresses CAN be modified before being broadcast to the rest of the network, however generally this results in the computer not receiving intended traffic and requires specialized software
Why ip address start with 255.255..?
the Ip address is used to broadcast messages, such as the Emergency Broadcast message recived on your television
A switch receives a frame with a destination MAC address that is currently not in the MAC table What action does the switch perform?
It duplicates the frame to all Ethernet ports, except the port it came from. A switch's MAC table is built not from destination addresses it receives, but by the source MAC addresses. So the frame is broadcast throughout the broadcast domain, until the end device with a matching MAC address responds to the broadcast, thus giving the switch a new source address to add to its MAC table.
Which protocol is used to determine a MAC address of a remote host interface?
ARP (address resolution protocol) is used in this case. Basically, one computer asks, for example, "who has IP address 10.0.0.15" (the message is sent as a broadcast), and the computer with this IP address replies, including its MAC address.ARP (address resolution protocol) is used in this case.

A switch received a frame with a destination mac address that is currently not in the mac table what action does the switch performs?
It will broadcast to every port in the vlan.
What action will a router take when it receives a frame with a broadcast MAC address?
It will not forward the frame to another network
Why does a switch flood a frame?
Because it is a broadcast frame Because it is a multicast Frame Because the switch has no MAC address for it.
When would a switch record multiple entries for a single switch port in its MAC address table?
A switch would record multiple entries for a single switch port in its MAC address table if it does not contain the Mac address of a particular destination in the address table. It will broadcast to all ports besides the port where entry comes from.
What is the broadcast MAC address in hexadecimal notation?
FF-FF-FF-FF-FF-FF
What do you understand by broadcast network?
When a packet arrives at the network layer on the sender's device, it is encapsulated into a frame whose destination MAC address is all fs (FF-FF-FF...). The switch connected to the sender's device recognizes the all fs MAC address as a broadcast message and hence forwards it to all its ports.
Why does a network host need to broadcast an ARP request?
A host on a network needs to broadcast an ARP request to advertise its Mac address. The networking world is very chatty in nature and when a new network host is available it immediately broadcasts its Mac address as with a ARP message. Also when a particular network host needs to send a data packet to another network host available in the same LAN whose Mac address is unknown, the first network host sends out a ARP message requesting for the destination network hosts MAC address.
How many destination MAC addresses can a message contain?
It can contain one MAC Address at a time, though if the message needs to be sent to all hosts on the network the message may contain the broadcast MAC Address, which is as follows: FFFF.FFFF.FFFF in hexidecimal notation, or a 48-bit address made up of all 1's in binary.
What is the difference between broadcast and point to point?
Broadcast means you sent digital signals to any device connected to a network. Point to point means you send digital signals from a specific point to a specific point (identified by IP address or MAC address).
What is the next step the host wil take to find the destination MAC address of another host?
This is achieved via the ARP protocol (the Address Resolution Protocol). The host sends out a request, basically asking "who has IP address so-and-so". The request, of course, is sent as a broadcast. If a computer has the specified IP address, it will reply with its MAC address.
