2. What is a WAN?

   • a network infrastructure to provide data storage, retrieval, and replication
   • a network infrastructure that provides access to other networks over a large geographic area
   • a network infrastructure covering a limited physical area, e.g. A city
   • a network infrastructure that allows access in a small geographic area
     
     Explanation:

     A WAN provides access to other networks over a large geographic area. A SAN provides data storage, recovery, and replication. A MAN covers a limited physical area, such as a city. A LAN provides access over a small geographic area.

3. Associate the Internet connection type with the appropriate description or role. (Not all options are used.)

   • MetroEthernet ——–>Business class high-speed copper or fiber connection
   • Satellite ——->requires a plate and clear vision to serve
   • SDSL ——->Business-class service offering the same upload and download speeds over phone lines
   • Cabo ———>Signal transmitted over the same copper or fiber optic medium as the television signal
   • Practical ——–>Mobile network access
     
     Explanation:

     DSL uses a high-speed modem to split the existing phone line into voice signaling, download and upload channels. SDSL is a DSL format that offers business-class service with the same download and upload speeds. The cable uses the same coaxial or fiber optic cable that carries television signals into the home to provide Internet access. The satellite requires a clear line of sight and is obstructed by trees and other obstacles. Mobile Internet access is provided via the mobile network. Cellular communications provide access to otherwise inaccessible areas. Metro Ethernet is a special commercial class of service that connects businesses to the Internet over copper or fiber optic cables at speeds up to 10 Gb/s.

   • suitable for modular devices that allow for expansion
   • offers a limited number of apps
     
     Explanation:

     Scalable networks are networks that can grow without requiring costly replacement of existing network equipment. One way to make a network scalable is to purchase modular networking equipment.

5. What three devices are considered end devices on a network? (Choose three.)

   • router
   • to change
   • VoIP-phone

   • Rot A ——–>MANN
   • Rot B——–>LAN
   • Rot C——–>W-lan
   • Rot D——–>BLASS
     
     Explanation:

     Network A is a MAN. It consists of a number of different types of facilities linked together within the same geographical area. Network B is a LAN. It is located in a limited geographic area in a single building. Network C is a WLAN. It is a LAN where devices connect wirelessly. Finally, option D shows a WAN. It's two geographically separate LANs connected to the same enterprise.

7. ANDArpanetThe project started with the development of connections between networks using TCP/IP, which has now become the Internet.

   • Hint: The correct answers can be 4:Arpanet,ARPANET,Branch network for advanced research projects, jAgency for advanced research projectsin netacad, but in our online system you can only useArpanet.

8. How is BYOD changing the way companies deploy networks?

   • BYOD requires companies to buy laptops instead of desktops.
   • BYOD users are responsible for their own network security, reducing the need for organizational security policies.
   • BYOD devices are more expensive than those purchased by an organization.
   • BYOD provides flexibility in where and how users can access network resources.
     
     Explanation:

     A BYOD environment requires an organization to support a variety of devices and access methods. Personal devices that are not under the company's control may be involved, so security is paramount. On-premises hardware costs are reduced, allowing an organization to focus on providing collaboration tools and other software to BYOD users.

9. In which scenario is it advisable to use a WISP?

   • an internet cafe in a city
   • a farm in a rural setting without a wired broadband connection
   • Any home with multiple wireless devices
   • an apartment in a building with wired internet access
     
     Explanation:

     Wireless Internet Service Providers (WISPs) are usually located in rural areas where DSL or cable access is not available. A satellite dish or antenna on the participant premises connects wirelessly to a WISP transmitter, eliminating the need for physical cabling outside the building.

10. What is an ISP?

    • It is a standards body that develops cabling and wiring standards for networks.
    • It is a protocol that defines how computers communicate on a local area network.
    • It is an organization that allows individuals and businesses to connect to the Internet.
    • It is a network device that combines the functionality of several different network devices into one.
      
      Explanation:

      An ISP, or Internet Service Provider, is an organization that provides Internet access to businesses and individuals.

    • Quality of Service (QoS)
    • scalability
    • Security
    • fault tolerance
    • integrity
      
      Explanation:

      Fault tolerance is the property of a network that allows it to respond quickly to failures in equipment, media, or network services. Quality of Service refers to the measures taken to ensure that network traffic that requires higher performance is given the required network resources. Scalability refers to the ability of the network to grow to meet new demands. Security refers to protecting networks and data from theft, alteration, or destruction. Integrity refers to the completeness of something and is not generally used as a characteristic of networks like other terms.
