Internet Protocols and Communication Quiz

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.

The transmission control protocol (TCP) and Internet protocol (IP) are used in Internet communication. Which of the following best describes the purpose of these protocols?

• To ensure that communications between devices on the Internet are above a minimum transmission speed

• To ensure that private data is inaccessible to unauthorized devices on the Internet

• To establish a common standard for sending messages between devices on the Internet

• To validate the ownership of encryption keys used in Internet communication

Which of the following actions are likely to be helpful in reducing the digital divide? PICK TWO ANSWERS

• Designing new technologies intended only for advanced users

• Designing new technologies to be accessible to individuals with different physical abilities

• Implementing government regulations restricting citizens’ access to Web content

• Having world governments support the construction of network infrastructure

Which of the following best explains how the Internet is a fault-tolerant system?

• 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.

Which of the following best explains how messages are typically transmitted over the Internet?

• 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 statements correctly explain how the Internet is able to facilitate communication at a large scale? SELECT ALL THAT APPLIES

• A central monitoring computer is used to track and maintain the connections of the Internet.

• Data is routed between points in multiple ways so that if a connection fails, the data can be rerouted around the inoperative connections.

• Protocols for packets and routing are used so that computers from different manufacturers can communicate in a standard way.

Internet protocol version 6 (IPv6) has been introduced to replace the previous version (IPv4). Which of the following best describes a benefit of IPv6 over IPv4?

• IPv6 addresses are shorter than IPv4 addresses, which allows for faster routing of packets.

• IPv6 allows for a greater number of addresses than IPv4, which allows more devices to be connected to the Internet.

• IPv6 eliminates the use of hierarchy in addressing, making addresses easier to use.

• IPv6 allows users to bypass older security protocols so that data can be sent peer-to-peer without the use of routers.

The figure below represents a network of physically linked devices, labeled A through F. A line between two devices indicates a connection. Devices can communicate only through the connections shown. Which of the following statements are true about the ability for devices A and C to communicate? Select two answers.

• If devices B and D were to fail, then information sent from device A could not reach device C.

• If devices B and F were to fail, then information sent from device A could not reach device C.

• If devices D and F were to fail, then information sent from device A could not reach device C.

• If devices E and F were to fail, then information sent from device A could not reach device C.

Which of the following best explains the relationship between the Internet and the World Wide Web?

• Both the Internet and the World Wide Web refer to the same interconnected network of devices.

• The Internet is an interconnected network of data servers, and the World Wide Web is a network of user devices that communicates with the data servers.

• The Internet is a local network of interconnected devices, and the World Wide Web is a global network that connects the local networks with each other.

• The Internet is a network of interconnected networks, and the World Wide Web is a system of linked pages, programs, and files that is accessed via the Internet.

Which of the following statements about the Internet is true?

• The Internet is a computer network that uses proprietary communication protocols.

• The Internet is designed to scale to support an increasing number of users.

• The Internet requires all communications to use encryption protocols.

• The Internet uses a centralized system to determine how packets are routed.
