ITN 100- FINAL EXAM QUESTIONS AND
ANSWERS 2026 VERIFIED.
Today, the most expensive part of the network is the hardware. - ANS True
Today, many organizations design networks using the building-block approach. - ANS True
The primary goal of the needs analysis step in network design is to develop a physical network
design. - ANS False
Simulation is a tool that can be used in designing networks. - ANS True
Cost assessment is the step in the network design in which many complex factors related to
costs are documented. - ANS True
When obtaining the support of senior management for a proposed network, it is important to
use as much technical network jargon as possible. - ANS False
The campus backbone is usually faster than the backbones used inside buildings. - ANS True
In the technology design stage of network design, - ANS the decisions for fundamental
technology/protocols and circuit capacity are interrelated

, ___________ refers to the amount of data transmitted on a circuit. - ANS Circuit loading
STP cable is least costly type of cable used in today's networks and is the most commonly used
cable type in connecting computers to switches. - ANS False
Discuss in detail how you would improve a LAN network's performance, and what you would
look for. - ANS Checking the physical cabling, ensuring switches and routers aren't
overloaded, and optimizing the network's topology.
Describe war-chalking, war-driving, and war-walking. - ANS War-chalking uses symbols on
sidewalks to show nearby Wi-Fi networks. War-driving is scanning for wireless networks while
driving, usually for mapping or security testing. War-walking is the same concept, but done on
foot.
Compare a switched Ethernet to a wireless Ethernet. What are four essential differences
between these two approaches to building a LAN? Give three reasons why a switched Ethernet
is preferable to wireless. Three reasons why wireless might be preferred to switched? - ANS A
switched Ethernet uses physical cable to provide dedicated, high speed, and stable connections.
Four essential differences between them: Medium of transmission, bandwidth and speed,
reliability and interference, and security. Three reasons why wireless is preferred: Mobility and
flexibility, lower installation effort, and scalability and convenience.
Select three different types of IEEE 802.11 and describe when it might be best to use each one. -
ANS 802.11n works best on both the 2.4 GHz and 5GHz bands.
802.11ac works best on the 5GHz band and delivers faster speeds ideal for activities like HD or
4K streaming.
802.11ax works best for crowded environments with many connected devices.
The Ethernet standard was first developed by the IEEE. - ANS False
