    Radio waves and microwaves are used in which of the following communications?

    • Voice over IP

    • IP Telephony

    • Wireless

    • Enterprise

    Correct Answer
    A. Wireless
    Explanation
    Radio waves and microwaves are used in wireless communications. Wireless communication refers to the transfer of information between two or more devices without the need for physical wired connections. Radio waves and microwaves are electromagnetic waves that can be used to transmit signals wirelessly, allowing for the transmission of data, voice, and other forms of communication over a distance. This can include various forms of wireless communication technologies such as Wi-Fi, Bluetooth, cellular networks, and satellite communication systems.

    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 parts separated by dots. Each part is represented by an 8-bit field, allowing for a total of 32 bits in an IP address. This notation allows for easy readability and understanding of the address structure.

  • 4. 

    Each network interface card is uniquely identified by its?

    • Transceiver type

    • Mac address

    • IP address

    • Wins address

    Correct Answer
    A. Mac address
    Explanation
    A network interface card (NIC) is uniquely identified by its MAC address. The MAC address is a unique identifier assigned to the NIC by the manufacturer. It is a 48-bit address that is used to identify devices on a network at the data link layer of the OSI model. The MAC address is essential for communication between devices on a local area network (LAN) as it ensures that data is sent to the correct device. The MAC address is independent of the network configuration, such as IP address or Wins address, and remains the same regardless of the network the device is connected to.

    The primary purpose of a network is?

    • Interconnect computers for ease of administration

    • Provide central access to workstation hard disks

    • Share resources

    • Provide increased security for all workstations

    Correct Answer
    A. Share resources
    Explanation
    The primary purpose of a network is to share resources. Networks allow multiple computers to connect and share files, printers, and other devices, enabling efficient collaboration and communication among users. By sharing resources, networks eliminate the need for each individual computer to have its own dedicated resources, reducing costs and improving productivity. Additionally, networks facilitate the sharing of internet connections, enabling all connected devices to access the internet simultaneously.

  • 6. 

    The connectivity device that is used to provide flexibility in cable management and troubleshooting is the?

    • Patch Panel

    • Repeater

    • Hub

    • Transceiver

    Correct Answer
    A. Patch Panel
    Explanation
    A patch panel is a connectivity device that provides flexibility in cable management and troubleshooting. It acts as a central point where multiple network cables can be connected and organized. It allows for easy identification and rearrangement of cables, making it convenient for troubleshooting and maintenance. By using patch cables, connections between different devices can be easily established or modified, without the need to directly manipulate the main cables. This makes patch panels an essential tool in networking infrastructure, providing a neat and efficient way to manage and troubleshoot cables.

    What is the purpose of a demilitarized zone on a network?

    • To only provide direct access to the nodes within the DMZ and protect the network behind it

    • To provide a place to put the honeypot

    • To scan all traffic coming through the DMZ to the internal network

    • To contain the network devices you wish to protect

    Correct Answer
    A. To only provide direct access to the nodes within the DMZ and protect the network behind it
    Explanation
    A demilitarized zone (DMZ) is a network segment that acts as a buffer zone between the internal network and the external network (usually the internet). The purpose of a DMZ is to only provide direct access to the nodes within it, such as web servers, while protecting the network behind it. By placing publicly accessible servers in the DMZ, organizations can limit the potential damage if these servers are compromised. The DMZ acts as a barrier, preventing direct access to the internal network and containing any potential threats within the DMZ itself.

    A computer must have an IP address when… (Select all correct answers )

    • Connecting to a home network router

    • Connecting to a Wi-Fi hotspot

    • Playing media from the hard drive

    • Communicating with another computer using TCP

    Correct Answer(s)
    A. Connecting to a home network router
    A. Connecting to a Wi-Fi hotspot
    A. Communicating with another computer using TCP
    Explanation
    A computer must have an IP address when connecting to a home network router, connecting to a Wi-Fi hotspot, and communicating with another computer using TCP. IP addresses are essential for establishing network connections and identifying devices on a network. When connecting to a home network router or a Wi-Fi hotspot, the computer needs an IP address to join the network and communicate with other devices. Similarly, when communicating with another computer using TCP (Transmission Control Protocol), IP addresses are used to establish a connection and exchange data between the two devices. However, playing media from the hard drive does not require an IP address as it is a local activity within the computer.

    Rate this question:

  • 9. 

    An IP address is a numeric quantity that identifies… (Select all correct answers )

    • The manufacturer of a computer

    • A network adapter to other devices on the network

    • The physical location of a computer

    • None of these answers

    Correct Answer
    A. A network adapter to other devices on the network
    Explanation
    An IP address is a numeric quantity that identifies a network adapter to other devices on the network. It serves as a unique identifier for each device connected to a network, allowing for communication and data transfer between devices. The IP address does not provide information about the manufacturer of a computer or the physical location of a computer.

    Let's start with an easy one. What does CPU stand for?

    • Computer Processing Unit

    • Central Peripheral Unit 

    • Central Processing Unit

    • Computer Processing User

    Correct Answer
    A. Central Processing Unit
    Explanation
    The correct answer is Central Processing Unit, it is the primary component of a computer that carries out instructions and performs calculations. It is often referred to as the "brain" of the computer, as it controls and coordinates all the activities of the computer's hardware and software.

  • 11. 

    Which of the following enables users to access files and to share a printer on a peer-peer network?

    • Share level security

    • User level security

    • User permissions

    • User account policies

    Correct Answer
    A. Share level security
    Explanation
    Share level security enables users to access files and share a printer on a peer-to-peer network. With share level security, users can set permissions and restrictions on shared resources such as files and printers, allowing or denying access to other users on the network. This ensures that only authorized users can access and use the shared resources, providing a level of control and security in a peer-to-peer network environment.

    The standard naming convention used to specify a path to a network resource is?

    • Naming services

    • FQDN

    • DNS

    • UNC

    Correct Answer
    A. UNC
    Explanation
    UNC stands for Universal Naming Convention. It is a standard naming convention used to specify a path to a network resource. UNC paths are commonly used in Windows operating systems to access shared files, folders, and printers on a network. UNC paths consist of a double backslash followed by the name of the computer or server, and then the name of the shared resource. Using UNC paths allows for easy and consistent access to network resources across different machines and operating systems.
