2.4.3 Network Components, Types, and Questions Quiz Answers. Networking Basics Module 2 quiz exam answers

1. 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

Explanation: 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.

2. What are two functions of end devices on a network? (Choose two.)

  • They originate the data that flows through the network.
  • They direct data over alternate paths in the event of link failures.
  • They filter the flow of data to enhance security.
  • They are the interface between humans and the communication network.
  • They provide the channel over which the network message travels.

Explanation: End devices originate the data that flows through the network. Intermediary devices direct data over alternate paths in the event of link failures and filter the flow of data to enhance security. Network media provide the channel through which network messages travel.

3. A home user is looking for an ISP connection that provides high speed digital transmission over regular phone lines. What ISP connection type should be used?

  • DSL
  • dial-up
  • satellite
  • cell modem
  • cable modem

Explanation: DSL is the best technology to use over existing phone lines. A lot of ISPs have a lookup on their website where you can enter your phone number and see if they can offer you service.

4. What type of internet connection would be best for a residence in a remote area without mobile phone coverage or wired connectivity?

  • dial-up
  • cellular
  • satellite
  • DSL

Explanation: Satellite internet service provides the best option for a home user that would otherwise have no internet connectivity at all. Cellular internet is only available in areas with mobile phone coverage.

5. Which term correctly describes the function of an ISP?

  • responsible for managing local networks
  • responsible for the maintenance of SOHO networks
  • responsible for providing the link between a private network and the internet.
  • responsible for providing security on private networks

Explanation: ISP stands for internet Service Provider. An ISP is responsible for providing the link between a private network, such as a home or business network, and the internet.

6. Which device is an intermediary device?

  • firewall
  • PC
  • server
  • smart device

Explanation: An intermediary device sends network messages toward a final destination. Examples of intermediary devices include a firewall, router, switch, multilayer switch, and wireless router.

7. Which scenario describes a peer-to-peer network?

  • Users access shared files from a file server.
  • A user visits a webpage on the company web site.
  • A user has shared a printer attached to the workstation.
  • Users print documents from a network printer that has a built-in NIC.

Explanation: In a peer-to-peer network there is no centralized or dedicated server. A user computer can be a client to request service from another user computer and a server to share a network resource (such as a printer) to other users.

8. Which term is used to describe a network device with the primary function of providing information to other devices?

  • workstation
  • console
  • server
  • client

Explanation: Servers are devices with software installed that allows them to provide information, like web pages or email.

9. What is an advantage of the peer-to-peer network model?

  • scalability
  • high level of security
  • ease of setup
  • centralized administration

Explanation: The simplest peer-to-peer network consists of two computers that are directly connected to each other through the use of a wired or wireless connection. The advantages of peer-to-peer networking include ease of setup, lower cost, and less complexity.

10. What is a characteristic of a peer-to-peer application?

  • Each device using the application provides a user interface and runs a background service.
  • Each device can act both as a client and a server, but not simultaneously.
  • The resources required for the application are centralized.
  • One device is designated a server and one device is designated a client for all communications and services.

Explanation: Peer-to-peer networks exist directly between client devices, with no centralized resources or authentication. Hybrid peer-to-peer systems also exist that decentralize resource sharing but can use centralized indexes to point to the resource locations.
