Which of the following is true for coaxial cables?
- A.
It uses copper wires, which are good conductors of electricity.
- B.
Coaxial cables provide effective protection against EMI during data transmissions.
- C.
It uses light rays instead of electricity to transmit data
- D.
It can be differentiated into two categories, single-mode and multimode
Correct Answer
B. Coaxial cables provide effective protection against EMI during data transmissions.Explanation
Coaxial cables provide effective protection against EMI (Electromagnetic Interference) during data transmissions. EMI is a disturbance caused by external electromagnetic signals that can interfere with the quality of data transmission. Coaxial cables are designed with an inner conductor, insulating layer, metallic shield, and outer insulating layer, which provides excellent shielding against EMI. This shielding helps to minimize the impact of external electromagnetic signals, ensuring a reliable and high-quality data transmission.Rate this question:

In case of 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 that is used for transmitting data over long distances in fiber-optic cables. Single mode fibers have a small core diameter, which allows for a single mode of light to propagate through the fiber. This results in less dispersion and attenuation, making it ideal for long-distance transmission where the signal needs to travel without significant loss or distortion.Rate this question:

What is the maximum bandwidth that can be supported by fiber optics cable?
- A.
10 Mbps
- B.
50 Mbps
- C.
2000 Mbps
- D.
100 Mbps
Correct Answer
C. 2000 MbpsExplanation
Fiber optics cables have the ability to transmit data at very high speeds due to their use of light signals. The maximum bandwidth that can be supported by fiber optics cable is 2000 Mbps. This means that the cable can transfer data at a rate of 2000 megabits per second, making it ideal for high-speed internet connections and other applications that require fast and reliable data transmission.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 and LLC are two sublayers of the Data Link layer. The Data Link layer is responsible for providing error-free transmission of data frames over a physical link. The MAC sublayer handles the addressing and access to the physical media, while the LLC sublayer handles flow control and error checking. Together, they ensure reliable communication between devices connected to the same network.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 in 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 connecting more than 1650000 hosts in the network. Class A addresses have a large range of network addresses, allowing for a maximum of 16,777,214 hosts per network. This would provide enough IP addresses to accommodate the large number of hosts in Vodafone Fiji Ltd's network.Rate this question:

Consider the following statements: Statement A: In Duplex transmission, either node can transmit while the other node can receive data Statement B: In half-duplex transmission, both the nodes can transmit as well as receive data at the same time. Which of the following is true with respect to 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 falseExplanation
In duplex transmission, both nodes can transmit and receive data simultaneously, allowing for bi-directional communication. However, in half-duplex transmission, only one node can transmit at a time while the other node receives, and vice versa. Therefore, statement A is true as it correctly describes duplex transmission, while statement B is false as it inaccurately describes 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 between devices without the need for physical wires or cables. This includes various forms of wireless communication such as Wi-Fi, Bluetooth, cellular networks, and satellite communication. Voice over IP (VoIP) and IP Telephony are examples of communication protocols that can be used over wireless networks, but they are not exclusive to wireless communication. Enterprise communication can also utilize wireless technologies, but it is not specific to radio waves and microwaves.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, which consists of four parts separated by dots. Each part is made up of 8 bits, resulting in a total of 32 bits for the entire address. This allows for a wide range of possible addresses, as each 8-bit field can have a value ranging from 0 to 255. Therefore, the correct answer is 8-bit fields.Rate this question:

Which of the following statements is NOT true regarding networks?
- A.
The first network called the ARPANET was created by DOD with the help of Advanced Research Projects Agency (ARPA).
- B.
Networks enable sharing of information across the multiple networks.
- C.
Networks enable centralization of data management.
- D.
Networks can be divided into four network topologies: mesh, cellular, star and bus.
Correct Answer
D. Networks can be divided into four network topologies: mesh, cellular, star and bus.Explanation
The statement "Networks can be divided into four network topologies: mesh, cellular, star and bus" is not true. Network topologies refer to the way in which devices are connected in a network, and there are more than just four topologies. Some other common network topologies include ring, tree, and hybrid.Rate this question:
