Networking Essentials (Version 2) – Modules 1 – 4: Internet Connection: Getting Online Pre-Test Exam Answers Full 100% 2021

  1. What is a characteristic of a SOHO network?

    • It consists of multiple LANs with backbone infrastructure connections.
    • It is a large network, such as those used by corporations and schools, with hundreds or thousands of interconnected hosts.
    • It is a collection of interconnected private and public networks.
    • It is a small network that connects a few computers to each other and to the internet.
      Answers Explanation & Hints:

      The SOHO network allows computers in a home office or a remote office to connect to a corporate network, or access centralized, shared resources.

  2. What is the delay in the amount of time for data to travel between two points on a network?

    • bandwidth
    • throughput
    • latency
    • goodput
      Answers Explanation & Hints:

      Latency is a term used to indicate delay when getting a packet from one point to another. Network connections with small amounts of delay are called low-latency networks, whereas network connections with long delays are called high-latency networks. High latency creates bottlenecks in any network communications.

  3. What type of network is defined by two computers that can both send and receive requests for resources?

    • client/server
    • peer-to-peer
    • enterprise
    • campus
      Answers Explanation & Hints:

      The simplest form of peer-to-peer networking consists of two computers that are directly connected to each other through the use of a wired or wireless connection.

  4. What is a role of an intermediary device on a network?

    • functions as the primary source of information for end devices
    • determines the path and directs data along the way to its final destination
    • runs applications that support collaboration for business
    • forms the interface between the human network and the underlying communication network
      Answers Explanation & Hints:

      Processes running on the intermediary network devices perform functions like regenerating and re-transmitting data signals, maintaining information about what pathways exist through the network and internetwork, directing data along alternate pathways when there is a link failure, and permitting or denying the flow of data, based on security settings.

  5. Which type of technology is used to provide digital data transmissions over cell phone networks?

    • 4G
    • Wi-Fi
    • NFC
    • Bluetooth
      Answers Explanation & Hints:

      3G, 4G, and 4G-LTE are technologies that are used to provide enhanced cell phone networks that are capable of fast data transmission.

  6. Which wireless technology is used on smart phones to transmit data to another device within only very close proximity?

    • NFC
    • Wi-Fi
    • 3G/4G
    • Bluetooth
      Answers Explanation & Hints:

      Near Field Communications (NFC) is a wireless technology that enables data to be exchanged by devices that are in very close proximity to each other.

  7. A traveling sales representative uses a cell phone to interact with the home office and customers, track samples, make sales calls, log mileage, and upload/download data while at a hotel. Which internet connectivity method would be a preferred method to use on the mobile device due to the low cost?

    • cellular
    • DSL
    • cable
    • Wi-Fi
      Answers Explanation & Hints:

      Mobile devices typically use either the cellular network or a Wi-Fi network to connect to the internet. The Wi-Fi connection is preferred because it uses less battery power and is free in many places.

  8. Which IP configuration parameter provides the IP address of a network device that a computer would use to access the Internet?

    • default gateway
    • host IP address
    • subnet mask
    • DNS server
      Answers Explanation & Hints:

      The types of IP configuration on a host device include these:
      IP address – identifies the host on the network.
      Subnet mask – identifies the network on which the host is connected.
      Default gateway – identifies the networking device that the host uses to access the Internet or another remote network.
      DNS server – identifies the server that is used to translate a domain name into an IP address.

  9. Refer to the exhibit. A student is working on a Packet Tracer lab that includes a home wireless router to be used for both wired and wireless devices. The router and laptop have been placed within the logical workspace. The student adds a laptop device and wants to replace the wired network card with a wireless network card.

      Answers Explanation & Hints:

      Any time you are removing or installing devices into a PC or laptop within Packet Tracer, turn the power off. For the Packet Tracer laptop, use the Physical tab and click on the power button to the immediate right of the power cord.

  10. Which type of cable connection would be used in Packet Tracer to connect a FastEthernet port on a PC to a switch port?

    • console
    • crossover
    • fiber
    • straight-through
      Answers Explanation & Hints:

      A FastEthernet straight-through cable is used to connect the FastEthernet0 port on a PC to a switch port.

  11. Refer to the exhibit. Which menu item would be used to bring up a web browser?

    • ping 192.168.1.1
    • ipconfig 192.168.1.1
      Answers Explanation & Hints:

      The traceroute (tracert) command is used to verify the path to a destination device. The ping command is used to verify Layer 3 connectivity. The ipconfig command is used to display the IP address on a device. ​

  16. What is a purpose of an IP address?

    • It identifies the physical location of a data center.
    • It identifies a location in memory from which a program runs.
    • It identifies a return address for replying to email messages.
    • It identifies the source and destination of data packets.
