Question 1

In terms of digital transmissions,_______ transfers data in small blocks based on the destination IP address.

Accepted Answer

Packet switching transfers data in small blocks called packets based on the destination IP address. Chunking refers to breaking up large files into smaller parts to enable easier transmission, but it does not involve the destination IP address. Circuit switching and IP streaming are different mechanisms for data transmission.

Question 2

Network capacity is measured in terms of its ________.

Accepted Answer

Network capacity is measured in terms of bandwidth, which refers to the amount of data that can be transmitted over a given amount of time. It is typically measured in bits per second (bps) or some multiple thereof, such as kilobits per second (Kbps) or megabits per second (Mbps). Protocol, size, and IP version are not measures of network capacity.

Question 3

________ is the method by which data are sent from one device to another via a network.

Accepted Answer

IP or Internet Protocol is the method by which data are sent from one device to another via a network. It is a protocol that is used for communication between devices on the internet or private networks. The other options listed do not represent this method of data transmission.

Therefore, the correct answer is D) IP.

Question 4

Bandwidth-intensive apps are important to business processes,but they also strain network capabilities and resources.One strategy for regulating a network's quality or service is to "prioritize traffic" which means:

Accepted Answer

Prioritizing traffic means allocating network resources in a way that ensures that critical data and applications, which are sensitive to time delay, are given priority on the network. This approach helps to maintain the quality of service for high-priority applications and prevent congestion and delays caused by bandwidth-heavy applications. Therefore, option B is the correct answer. Option A is not a feasible or practical solution, as seniority in the organization does not necessarily reflect the importance of data traffic. Option C is not a viable solution as it does not address the issue of bandwidth-intensive applications. Option D may not be optimal as it restricts traffic for voice and video apps altogether, rather than prioritizing them based on their importance.

Question 5

Sony realized that the technical limitations of____ were making it urgent to move to ________.

Accepted Answer

IPv4 addresses have a limitation in the number of unique addresses that can be assigned, which is why there was a need to move to IPv6 which allows for a much larger pool of available addresses. Sony realized this technical limitation and thus had to move to IPv6.

Question 6

Every device that communicates with a network must have a unique identifying ________

Accepted Answer

An IP address is a unique identifier assigned to every device that communicates with a network. This is necessary to ensure that data is correctly sent and received between devices. The other choices are not identifiers for devices on a network.

Question 7

In terms of network capacity,a pipeline analogy is often used.The larger the diameter of the pipe,the greater the throughput (volume)of water that flows through it and the faster water is being transferred through it.This analogy refers to a network's ___________.

Accepted Answer

The analogy of a pipeline refers to the network's bandwidth, which is the maximum amount of data that can be transmitted over a specific period. Just as a larger diameter pipe can transport more water at a faster rate, a higher bandwidth network can transmit more data at a faster rate.

Question 8

Which of the following decides how the digital 1's and 0's are represented in terms of voltage and frequencies?

Accepted Answer

Modulation and coding techniques are used to convert the digital 1's and 0's into analog signals that can be transmitted over a communication channel. Modulation methods determine how the digital information is represented by different carrier signals, while coding techniques ensure that the information is transmitted reliably and efficiently. The voltage and frequencies used to represent the digital information depend on the modulation and coding scheme employed. Therefore, option D is the correct choice. Options A, B, and C are not relevant to this context.

Question 9

Network ________ are devices that transmit ________from their source to their destination based on IP addresses.

Accepted Answer

Switches and routers are both network devices that transmit data packets from their source to their destination based on IP addresses. APIs are used for software communication rather than network transmission, and while routers do transmit digital signals, they also evaluate and route data packets. Firewalls are used to manage network security, and while they do interact with data packets, their primary function is not transmission.

Question 10

With _________,voice and data transmissions travel in packets over telephone wires.

Accepted Answer

VoIP (Voice over Internet Protocol) is a technology that enables voice and data transmissions to travel in packets over telephone wires or internet connections. It converts analog voice signals into digital data packets using compression techniques, thereby allowing real-time voice communication over IP networks. MP3 or MP4 are audio and video file formats, respectively, that are used for encoding and compressing digital media files. TCP/IP is a protocol used for transmitting data over networks, while Wi-Fi is a technology used for wireless networking. However, neither of these options specifically address the question of how voice and data transmissions travel over telephone wires.

Question 11

To insure QoS of a network,an alternative to "prioritizing traffic" is to __________,which means holding back traffic from non-time sensitive apps so that apps like voice and video run more effectively.

Accepted Answer

Throttling traffic involves limiting or controlling the amount of data that is allowed to pass through a network, which can be a more effective approach to ensuring QoS than prioritizing traffic. By throttling non-time sensitive applications, bandwidth is freed up for more critical applications like voice and video, which should lead to improved performance and fewer disruptions. Blocking traffic, re-directing traffic or filtering traffic are not effective alternatives to prioritizing traffic for maintaining QoS.

Question 12

Basic functions of business networks are all of the following except _______.

Accepted Answer

Routers are a networking hardware device used to connect multiple devices together, but they are not a function of business networks. The basic functions of business networks are search (finding information or resources), mobility (ability to work from anywhere), and collaboration (working together with others).

Question 13

Which of the following about IPv4 is false?

Accepted Answer

IPv4 may require manual configuration, and changing ISP may require significant effort.

Question 14

_________ networks are high capacity digital networks.

Accepted Answer

Broadband networks are high capacity digital networks that can transmit multiple types of data, including voice, video, and internet. Circuit networks are analog networks that transmit voice signals only, and narrowband networks have a limited capacity to transmit data. While the term "smart grid" refers to a specific type of electrical power distribution system, it is not directly related to digital networks.

Question 15

An important management decision concerns the network's _________ especially for delay-sensitive data such as real-time voice and high-quality video.

Accepted Answer

Quality of service (QoS) refers to the ability of a network to prioritize certain types of traffic and ensure reliable and timely delivery of that traffic. This is particularly important for delay-sensitive data such as real-time voice and high-quality video, which can be adversely affected by network congestion or delays. Therefore, managing the network's QoS is an important decision for ensuring the efficient and effective delivery of these types of data.

Question 16

Investments in data networks,IP addresses,routers,and switches are ________ because of their impact on productivity,security,user experiences,and customer service.

Accepted Answer

Investments in data networks, IP addresses, routers, and switches are business decisions because they impact productivity, security, user experiences, and customer service. These decisions involve allocating resources to maximize the return on investment and achieve business objectives. Tactical issues and technology decisions may be involved in the planning and execution of these investments, but ultimately, they are made with the overall business strategy in mind.

Question 17

All generations of networks are based on ________.

Accepted Answer

All generations of networks are based on switching, which is the process of connecting different devices and allowing them to communicate with each other. Circuit switching was used in 1G networks, while packet switching was introduced in 2G and is still used in modern networks. Wireless and cloud technologies have been developed to improve network connectivity, but they are not the basis of the network itself.

Question 18

____________ is older technology for transmitting signals that originated with telephone calls;and is inefficient for digital transmission.

Accepted Answer

Circuit switching is an older technology used for transmitting signals that originated with telephone calls. It is not efficient for digital transmission as it requires a dedicated physical connection for the duration of the call, whereas packet switching allows multiple digital transmissions to share a single physical connection. Chunking and IP streaming are not related technologies for signal transmission.

Question 19

_____________ are the rules and standards that govern how devices on a network exchange data and talk to each other.

Accepted Answer

Network protocols such as TCP/IP, HTTP, and FTP define the rules and standards for how devices on a network communicate with each other. These protocols ensure that data is transmitted efficiently and reliably between devices. Security settings, organization IT policies, and traffic priority procedures are all important aspects of network management, but they are not the specific rules and standards that govern data exchange on a network.

Question 20

Which of the following is not one of the basic functions of business networks?

Accepted Answer

Strategic planning may be a benefit of business networks, but it is not one of the basic functions. The basic functions are relationships, search, and communication.
