ITN Chapter 1 EXAM with complete
solutions 2024/2025
Match each characteristic to its corresponding Internet connectivity type. (Not all
options are used.) - ANSWER-DSL: High Bandwidth connection that runs over
telephone lines.
Dialup Telephone: Typically has very low bandwidth
Satellite: Not suited for heavily wooded areas.
Cable: Uses coaxial cable as medium
Explanation:
DSL is an always-on, high bandwidth connection that runs over telephone lines.
Cable uses the same coaxial cable that carries television signals into the home to
provide Internet access. Dialup telephone is much slower than either DSL or
cable, but is the least expensive option for home users because it can use any
telephone line and a simple modem. Satellite requires a clear line of sight and is
affected by trees and other obstructions. None of these typical home options use
dedicated leased lines such as T1/E1 and T3/E3
What security violation would cause the most amount of damage to the life of a
home user? - ANSWER-capturing of personal data that leads to identity theft
Explanation:
On a personal PC, denial of service to servers, worms and viruses, and spyware
producing spam emails can be annoying, invasive, and frustrating. However,
identity theft can be devastating and life altering. Security solutions should be in
place on all personal devices to protect against this type of threat.
, Which two Internet connection options do not require that physical cables be run
to the building? (Choose two.) - ANSWER-- Satellite
- Cellular
Explanation:
Cellular connectivity requires the use of the cell phone network. Satellite
connectivity is often used where physical cabling is not available outside the
home or business.
What are two functions of end devices on a network? (Choose two.) - ANSWER--
They are the interface between humans and the communication network.
- They originate the data that flows through the network.
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.
What two criteria are used to help select a network medium from various network
media? (Choose two.) - ANSWER-- the environment where the selected medium is
to be installed
- the distance the selected medium can successfully carry a signal
Explanation:
Criteria for choosing a network medium are the distance the selected medium can
successfully carry a signal, the environment in which the selected medium is to
be installed, the amount of data and the speed at which the data must be
transmitted, and the cost of the medium and its installation.
