The default subnet mask for the IP address is 198.133.219.4:

• <variant>255.255.255.255

• <variant>255.255.255.254

• <variant>255.255.0.0

• <variant>255.0.0.0

• <variant>255.255.255.0

The characteristics of a group mailing list:

• routers will route group addresses between 224.0.0.0 and 224.0.0.255.

• one packet can be sent to a group of nodes.

• the group mailing source address ranges from 224.0.0.0 to 224.0.0.255.

• computers use multicast to request IPv4 addresses.

• group mailing messages convert low-level addresses to high-level addresses.

Benefits of using fiber optic cable to connect devices:

• Fiber optic cable is typically used in small corporate and home networks.

• Fiber optic cable is easy to install.

• Fiber optic cable uses additional shielding to protect the copper wires.

• The fiber optic cable uses an RJ-45 connector.

• Fiber optic cable is resistant to electromagnetic and high frequency interference.

The user wants to test the connection between node 3 and node 8 on the network. To check the connection, you can use the command:

• ipconfig

• >netstat

• ipconfig /all

• nslookup

• ping

• placement of electrical signals on a carrier for transmission

• encapsulating a data packet into a frame

• segmentation and identification of data for reassembly at destination

• selection of the appropriate route for data transmission over the network
