Free Network-and-Security-Foundation Practice Questions

Explore 5 free practice questions for the WGU Network-and-Security-Foundation exam and review the answers and explanations to support your preparation.

  1. Question 1

    Single answer

    An organization is evaluating its internal network. Currently, each device is connected to two
    adjacent devices, one on either side.
    Which type of network topology is being used?

    • Option A:
      Point-to-point
      Correct
    • Option B:
      Bus
      Correct
    • Option C:
      Star
      Correct
    • Option D:
      Ring
      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: D

    Explanation

    A Ring topology is a network setup where each device is connected to two adjacent devices, forming
    a circular path for data transmission. This topology ensures that data travels in a single or
    bidirectional loop.
    Point-to-point topology refers to a direct connection between two devices without forming a larger
    network structure.
    Bus topology has all devices connected to a single central cable, rather than forming a ring.
    Star topology features a central hub or switch that connects all devices, rather than direct device-todevice
    links.

  2. Question 2

    Single answer

    A library has a network that allows patrons to use their mobile devices to connect to the internet.
    Which type of network is described?

    • Option A:
      SAN
      Correct
    • Option B:
      MAN
      Correct
    • Option C:
      PAN
      Correct
    • Option D:
      WLAN
      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: D

    Explanation

    A Wireless Local Area Network (WLAN) enables wireless connectivity within a defined geographic
    area, such as a library, office, or coffee shop. WLANs use Wi-Fi technology to allow users to access
    the internet without physical cables.
    Storage Area Networks (SANs) are used for data storage and do not provide internet connectivity to
    users.
    Metropolitan Area Networks (MANs) cover larger areas, such as cities, and are not used within a
    single building.
    Personal Area Networks (PANs) connect personal devices like smartphones and laptops over short
    distances, such as via Bluetooth, but do not support public internet access.

  3. Question 3

    Single answer

    An individual has been tasked with setting up an office network. During the process, there is a need
    for a device that extends the range of a network.
    Which device should be used?

    • Option A:
      Router
      Correct
    • Option B:
      Access point
      Correct
    • Option C:
      Server
      Correct
    • Option D:
      Switch
      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: B

    Explanation

    An access point (AP) is a network device that extends the coverage of a wireless network by acting as
    a bridge between wired and wireless devices. It allows users to connect to a network without needing
    a direct wired connection. APs are particularly useful in large office spaces where Wi-Fi signals may
    not reach all areas.
    Routers primarily manage network traffic but do not directly extend network range unless they
    include built-in AP functionality.
    Servers are used for hosting applications and storing data but do not extend network connectivity.
    Switches connect wired devices within a local network but do not extend wireless network range.

  4. Question 4

    Single answer

    When setting up a network, a technician needs a router that creates an access point.
    Which router should be used?

    • Option A:
      Wireless router
      Correct
    • Option B:
      Broadband router
      Correct
    • Option C:
      Core router
      Correct
    • Option D:
      Inter-provider border router
      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: A

    Explanation

    A wireless router is designed to create an access point that allows wireless devices to connect to a
    network. It combines the functions of a traditional router with a wireless access point, enabling
    communication between wired and wireless devices. These routers use Wi-Fi standards (e.g.,
    802.11ac, 802.11ax) to transmit data wirelessly.
    Broadband routers primarily provide internet connectivity but do not necessarily include Wi-Fi
    functionality unless specified.
    Core routers handle large-scale data routing in the backbone of networks but are not designed for
    access point creation.
    Inter-provider border routers function at an ISP level for routing traffic between different networks,
    not for providing user access.

  5. Question 5

    Single answer

    When setting up a network, a technician needs a router that connects computers together and
    connects computers to the internet.
    Which router should be used?

    • Option A:
      Inter-provider border router
      Correct
    • Option B:
      Subscriber edge router
      Correct
    • Option C:
      Broadband router
      Correct
    • Option D:
      Core router
      Correct
    Show Answer & Explanation Hide Answer & Explanation

    Correct Answer: C

    Explanation

    A broadband router is a type of network router that connects multiple computers within a local
    network while also providing internet access. It functions as a gateway between the local network
    and the internet by handling data packet transmission and routing. Broadband routers are widely
    used in small offices and homes because they offer essential networking services, including DHCP,
    NAT, and sometimes wireless connectivity.
    Inter-provider border routers are used by ISPs to route data between different providers and do not
    serve as an internet gateway for end users.
