Onsite hardware costs will be reduced, allowing a business to focus on delivering collaboration tools and other software to BYOD users.

Problem 14

Question :

In which scenario would the use of a WISP be recommended?

Answer Option Choices :

an Internet cafe in a city
a farm in a rural area without wired broadband access
any home with multiple wireless devices
an apartment in a building with cable access to the Internet

Correct Answer :

a farm in a rural area without wired broadband access

Explanation :

Refer to curriculum topic: 1.4.2
Wireless Internet Service Providers (WISPs) are typically found in rural areas where DSL or cable access is not available. A dish or antenna on the property of the subscriber connects wirelessly to a WISP transmitter, eliminating the need for physical cabling outside the building.

Problem 14

Question :

Question List Option Choices :

Correct Answer :

Question
Metro Ethernet high-speed business class copper or fiber connection
satellite requires a dish and clear line of sight for service
SDSL business class service that provides the same upload and download speeds over telephone lines
cable signal carried on the same copper or fiber medium as the television signal
cellular access via the cell phone network

Other Incorrect Match Options :

typically has very low bandwidth

Explanation :

Refer to curriculum topic: 1.2.4
DSL uses a high-speed modem to split the existing telephone line into voice, download, and upload signal channels. SDSL is a format of DSL that provides business class service featuring the same speeds for uploading and downloading. Cable uses the same coaxial or fiber optic cable that carries television signals into the home to provide Internet access. Satellite requires a clear line of sight and is affected by trees and other obstructions. Cellular access to the internet is provided by the cell phone network. Cellular provides access in areas that otherwise have no other form of access. Metro Ethernet is a dedicated business class of service that connects organizations to the internet via copper or fiber cable at speeds up to 10Gb/s.
