AP CSP Internet & Fault Tolerance (4.1 & 4.2)

Front

Which of the following best explains how messages are typically transmitted over the Internet? Options: The message is broken into packets that are transmitted in a specified order. Each packet must be received in the order it was sent for the message to be correctly reassembled by the recipient’s device. The message is broken into packets. The packets can be received in any order and still be reassembled by the recipient’s device. The message is broken into two packets. One packet contains the data to be transmitted and the other packet contains metadata for routing the data to the recipient’s device. The message is transmitted as a single file and received in whole by the recipient’s device.

Which of the following is a primary reason for the use of open protocols on the Internet? Open protocols allow devices to specify how data packets are to be routed on the Internet in advance. Open protocols ensure that all data transmission on the Internet is kept secure. Open protocols ensure that all Internet users are provided connections with equal bandwidth. Open protocols provide a way to standardize data transmission between different devices.

Which of the following best describes the relationship between the World Wide Web and the Internet? Options: The World Wide Web is a protocol that is accessed using a data stream called the Internet. The World Wide Web is a system of linked pages, programs, and files that is accessed using a data stream called the Internet. The World Wide Web is a system of linked pages, programs, and files that is accessed via a network called the Internet. The World Wide Web is a Web site that is accessed using a protocol called the Internet.

Which of the following statements best explains the ability of the network to provide fault tolerance?
Options:
The network is considered fault-tolerant because there are redundant paths between each pair of devices.
The network is considered fault-tolerant because it guarantees that no individual component will fail.
The network is not considered fault-tolerant because it relies on physical connections.
The network is not considered fault-tolerant because it provides more paths than are needed.

Back

The network is considered fault-tolerant because there are redundant paths between each pair of devices.

Front

Which of the following best explains how fault tolerance in a network is achieved?
Options:
By providing high-bandwidth connections between devices, enabling data packets to be transmitted as quickly as possible
By providing multiple paths between devices, enabling routing to occur even in the presence of a failed component
By providing open network protocols, ensuring that all devices on the network are interacting in a standard way
By providing software to monitor all network traffic, ensuring that data packets are sent and received in the proper order

Back

By providing multiple paths between devices, enabling routing to occur even in the presence of a failed component

Front

Which of the following best explains how the Internet is a fault-tolerant system? Options: The Internet is fault-tolerant because cybercriminals can conceal their actions, allowing them the ability to carry out faulty actions without leaving a trace. The Internet is fault-tolerant because there are usually multiple paths between devices, allowing messages to sometimes be sent even when parts of the network fail. The Internet is fault-tolerant because users can transmit messages using a variety of different protocols, allowing them to use devices from any manufacturer. The Internet is fault-tolerant because users usually understand and accept the fact that servers sometimes fail, allowing network engineers to repair faulty devices as quickly as possible.
