Unit 2 - Internet

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

• 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 is a primary reason for the use of open protocols on the Internet?

• Open protocols provide a way to standardize data transmission between different devices.

• Open protocols ensure that all Internet users are provided connections with equal bandwidth.

• Open protocols ensure that all data transmission on the Internet is kept secure.

• Open protocols allow devices to specify how data packets are to be routed on the Internet in advance.

Which of the following best explains how fault tolerance in a network is achieved?

• 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

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 has a block of IP addresses to handout as new devices join a network?

• Routers

• Domain Name Service (DNS)

• Dynamic Host Configuration Protocol

• Web Server

What is the minimum number of connections that would need to be removed from the network in order for device A to not be able to communicate with device F?

• 2

• 3

• 4

• 5

If you transmit live streaming of a sporting event where speed is more important than accuracy, what type of protocol would be employed?

• IP

• TCP

• UDP

• HTTP

Which of the following DOES NOT affect bandwidth?

• the number of devices on the network

• the type of network traffic

• the number of transmission errors

• the computers RAM

The agreed-upon set of rules that specify the behavior of some system that allow new technologies to adapt and communicate.

• High Bandwidth

• Protocols

• IP Addresses

• Domain Name System (DNS)

An IP address is more easily recognized by most users through which of the following?

• DNS

• Protocols

• Internet Protocol

• Active Directory
