  • 2. 

    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(.).

    • 8-bit fields

    • 4-bit fields

    • 6-bit fields

    • 2-bit fields

    Correct Answer
    A. 8-bit fields
    Explanation
    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.

    Media Access Control (MAC) and Logical Link Control (LLC) are two sublayers of _________________.

    • Session layer

    • Network layer

    • Transport layer

    • Data Link layer

    Correct Answer
    A. Data Link layer
    Explanation
    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.

    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?

    • Class B

    • Class A

    • Class C

    • Class D

    Correct Answer
    A. Class A
    Explanation
    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.

    What is the maximum bandwidth that can be supported by fiber optics cable?

    • 1000 Mbps

    • 50 Tbps

    • 10 Gbps

    • 100 Tbps

    Correct Answer
    A. 100 Tbps
    Explanation
    Fiber optics cables offer high-speed data transmission through the use of light signals. With bandwidths ranging from 10 Gbps to an impressive 100 Tbps, these cables enable rapid and reliable communication, making them crucial in modern networks for data-intensive applications, telecommunications, and internet services.

  • 6. 

    Which of the following is true for coaxial cables?

    • Coaxial cables use copper wires, which are good conductors of electricity.

    • Coaxial cables provide adequate protection against EMI during data transmissions.

    • Coaxial cables use light rays instead of electricity to transmit data.

    • 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.

    ARPA stands for ___________________________.

    • Advanced Research Projects Administration

    • Advanced Repeater Projects Agency

    • Advanced Research Projects Agency

    • Advanced Rear Projects Agency

    Correct Answer
    A. Advanced Research Projects Agency
    Explanation
    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.

    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?

    • Both statements, A and B, are false.

    • Statement A is false, and statement B is true.

    • Both statements, A and B, are true.

    • Statement A is true, and statement B is false.

    Correct Answer
    A. Statement A is true, and statement B is false.
    Explanation
    Duplex transmission allows communication in both directions. In full-duplex, both nodes can transmit and receive simultaneously (like a telephone call). In half-duplex, nodes can both send and receive, but only one at a time (like a walkie-talkie). Statement A correctly describes duplex as allowing two-way communication. However, Statement B incorrectly claims that both nodes can transmit and receive at the same time in half-duplex, which is false—this simultaneous communication only applies to full-duplex, not half-duplex.

  • 9. 

    Regarding fiber-optic cables, which transmission mode is used for transmitting data over long distances?

    • Infrared

    • Radio

    • Single-mode

    • Multimode

    Correct Answer
    A. Single-mode
    Explanation
    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:

  • 10. 

    Which of the following statements is NOT true regarding networks?

    • The first network, called the ARPANET, was created by DOD with the help of the Advanced Research Projects Agency (ARPA).

    • Networks enable sharing of information across multiple networks.

    • Networks enable the centralization of data management.

    • Networks can be divided into four network topologies: mesh, cellular, star, and bus.

    Correct Answer
    A. Networks enable the centralization of data management.
