Which of the following is true for coaxial cables?
- A.
Coaxial cables use copper wires, which are good conductors of electricity.
- B.
Coaxial cables provide adequate protection against EMI during data transmissions.
- C.
Coaxial cables use light rays instead of electricity to transmit data.
- D.
Coaxial cables can be differentiated into two categories, single-mode and multimode.
Correct Answer
A. Coaxial cables use copper wires, which are good conductors of electricity.Explanation
Coaxial cables use copper wires, which are good conductors of electricity. This is because copper has low resistance to the flow of electric current, allowing for efficient transmission of signals through the cable. The use of copper wires in coaxial cables helps to minimize signal loss and maintain high-quality transmission.Rate this question:

Regarding fiber-optic cables, which transmission mode is used for transmitting data over long distances?
- A.
Infrared
- B.
Radio
- C.
Single-mode
- D.
Multimode
Correct Answer
C. Single-modeExplanation
Single-mode is the correct answer because it is the transmission mode used for transmitting data over long distances in fiber-optic cables. Single-mode cables have a smaller core diameter, allowing for a single beam of light to travel straight down the center of the cable without bouncing off the walls. This minimizes signal loss and allows for longer transmission distances. In contrast, multimode cables have a larger core diameter, which allows multiple beams of light to travel through the cable, but this can cause signal distortion and limits the distance over which data can be transmitted.Rate this question:

What is the maximum bandwidth that can be supported by fiber optics cable?
- A.
1000 Mbps
- B.
50 Tbps
- C.
200 Tbps
- D.
100 Tbps
Correct Answer
C. 200 TbpsExplanation
Fiber optics cables have the ability to transmit data at extremely high speeds due to their use of light signals. The maximum bandwidth that can be supported by fiber optics cables is significantly higher compared to other types of cables. In this case, the correct answer is 200 Tbps, which indicates that fiber optics cables can support a maximum bandwidth of 200 terabits per second. This demonstrates the immense capacity of fiber optics technology in transmitting large amounts of data quickly and efficiently.Rate this question:

Media Access Control (MAC) and Logical Link Control (LLC) are two sublayers of _________________.
- A.
Session layer
- B.
Network layer
- C.
Transport layer
- D.
Data Link layer
Correct Answer
D. Data Link layerExplanation
MAC (Media Access Control) and LLC (Logical Link Control) are two sublayers of the Data Link layer in the OSI model. The Data Link layer is responsible for providing reliable and error-free communication between two directly connected devices. The MAC sublayer handles the addressing and access to the physical media, while the LLC sublayer manages the flow control and error detection of the data being transmitted. Therefore, the correct answer is the Data Link layer.Rate this question:

Salen Chetty is the network administrator of Vodafone Fiji Ltd. He needs to design the network setup for his company. More than 1650000 hosts will be connected to the network. Which IP addressing class would best meet his requirements?
- A.
Class B
- B.
Class A
- C.
Class C
- D.
Class D
Correct Answer
B. Class AExplanation
Class A IP addressing would best meet the requirements of Salen Chetty for designing the network setup for Vodafone Fiji Ltd. Class A provides a large range of IP addresses, allowing for more than 16 million hosts to be connected to the network. As there are more than 1,650,000 hosts in this case, Class A would be the most suitable choice. Class B and Class C have smaller ranges, while Class D is reserved for multicast addresses.Rate this question:

Consider the following statements: Statement A: In Duplex transmission, either node can transmit while the other can receive data.Statement B: In half-duplex transmission, both nodes can transmit as well as receive data at the same time. Which of the following is true concerning the above statements?
- A.
Both statements, A and B, are false.
- B.
Statement A is false, and statement B is true.
- C.
Both statements, A and B, are true.
- D.
Statement A is true, and statement B is false.
Correct Answer
D. Statement A is true, and statement B is false.Explanation
Statement A is true because in duplex transmission, one node can transmit data while the other node receives data. However, statement B is false because in half-duplex transmission, only one node can transmit data at a time while the other node is in a receiving mode. Both nodes cannot transmit and receive data simultaneously in half-duplex transmission.Rate this question:

Radio waves and microwaves are used in which of the following communications?
- A.
Voice over IP
- B.
IP Telephony
- C.
Wireless
- D.
Enterprise
Correct Answer
C. WirelessExplanation
Radio waves and microwaves are used in wireless communications. Wireless communication refers to the transmission of information without the use of physical connections or wires. Radio waves and microwaves are electromagnetic waves that can be used to transmit signals over long distances. They are commonly used in various wireless communication systems such as mobile phones, Wi-Fi networks, Bluetooth devices, and satellite communications. Therefore, the correct answer is "Wireless".Rate this question:

IP addresses exist in the numeric format of XXX.YYY.ZZZ.AAA. This format of specifying addresses is referred to as the dotted decimal notation. Each address consists of four __________ separated by dots(.).
- A.
8-bit fields
- B.
4-bit fields
- C.
6-bit fields
- D.
2-bit fields
Correct Answer
A. 8-bit fieldsExplanation
IP addresses are represented in the dotted decimal notation, where each address is divided into four 8-bit fields separated by dots. This notation allows for easy identification and organization of IP addresses, as each field represents a specific portion of the address.Rate this question:

ARPA stands for ___________________________.
- A.
Advanced Research Projects Administration
- B.
Advanced Repeater Projects Agency
- C.
Advanced Research Projects Agency
- D.
Advanced Rear Projects Agency
Correct Answer
C. Advanced Research Projects AgencyExplanation
ARPA stands for Advanced Research Projects Agency. This agency was established in 1958 by the United States Department of Defense. Its main purpose was to develop new technologies and conduct research in various fields, including science, technology, and engineering. ARPA played a crucial role in the development of the internet, as it funded the creation of ARPANET, the precursor to the modern internet. The agency's name was later changed to DARPA (Defense Advanced Research Projects Agency) in 1972.Rate this question:
