Multiple Choice
This diagram shows a number of computing devices connected to the Internet with each line representing a direct connection. Device A is attempting to send data over the Internet to Device E. Which of the following is true of how the data will travel through the network?
The data will always travel through Device B as it is the shortest path
The data will never be sent to Device G since there are other shorter paths available
It is possible that the data travels through any of the devices in the network before arriving at device E
If the data travels through Device D then it will not travel through Device B
24
Multiple Choice
Which of the following is true of how the Internet has responded to the increasing number of devices now using the network?
The Internet protocols are changed every year to adapt to the new devices that have been connected to the network
While the number of devices connected to the Internet has grown, the network itself has not grown
The protocols of the Internet were designed to scale as new devices are added
The protocols of the Internet are no longer necessary thanks to the large number of devices now connected to the network
25
Multiple Choice
Emilee is watching an online video. The video is being sent to her laptop by a server over the Internet which splits the video into packets and sends them in the order they appear in the video. Which of the following is true about how the packets will arrive at her computer?
The packets will always be received in the order that they were sent
Either every packet will reach her computer or none of them will.
Packets that arrive out of order will be sent back to the server.
The packets may arrive out of order
26
Multiple Choice
Which of the following best describes the purpose of an IP address?
IP addresses provide a unique number for identifying devices that send and receive information on the Internet
IP addresses assist in the reconstruction of a message that has been divided into many packets
27
Multiple Choice
Two devices are connected to the Internet and communicating with one another. A squirrel chews through one of the wires in the network that is currently being used by the devices to communicate. The network immediately begins using a different path through the network and communication continues as normal. This situation best exemplifies which principle?
fault-tolerance
scalability
protocol
pathing
28
Multiple Choice
An Internet Service Provider (ISP) is a company that builds the routers and wired connections that allow individuals to access the Internet. An ISP is considering adding additional redundant connections to its network. Which of the following best describes why the company would choose to do so?
It costs less to design a network that is redundant
The protocols of the Internet only work on networks that are redundant
Redundant networks are more reliable
Adding additional connections reduces the fault-tolerance of the network
29

31
Multiple Choice
Which of the following best describes the protocols used on the Internet?
