ITN 100 FINAL EXAMINATION SCRIPT
2026 QUESTIONS WITH ANSWERS
GRADED A+
>> Today, the most expensive part of the network is the hardware. (True/False)
Answer: False. (It's often network management/operations, not just hardware.)
>> Today, many organizations design networks using the approach.
Answer: Building-block
>> The primary goal of the needs analysis step in network design is to develop a physical network
design. (True/False)
Answer: False. (The primary goal is to understand what the network must do, not the physical design.)
>> is a tool that can be used in designing networks.
Answer: Simulation
>> is the step in network design where many complex factors related to costs are documented.
Answer: Cost assessment
>> When obtaining the support of senior management for a proposed network, it is important to use
as much technical network jargon as possible. (True/False)
Answer: False. (It's important to avoid jargon and focus on business benefits.)
>> The campus backbone is usually than the backbones used inside buildings.
Answer: Faster
>> In the technology design stage of network design, the decisions for fundamental
technology/protocols and are interrelated.
Answer: Circuit capacity
>> refers to the amount of data transmitted on a circuit.
Answer: Circuit loading
>> STP cable is the least costly type of cable used in today’s networks and is the most commonly
used cable type in connecting computers to switches. (True/False)
Answer: False. (UTP is typically less costly and more common.)
>> Describe the characteristics of 100BaseT Ethernet.
Answer: 100 Mbps, twisted pair, baseband, star topology
, >> List ways to improve LAN performance.
Answer: Upgrade switches, segment traffic, reduce collisions, optimize bandwidth, monitor traffic for
bottlenecks
>> Define war-chalking.
Answer: Marking locations with Wi-Fi access info
>> Define war-driving.
Answer: Driving around detecting Wi-Fi
>> Define war-walking.
Answer: Walking around detecting Wi-Fi
>> Describe 802.11n.
Answer: High speed, suitable for indoor/outdoor use
>> Describe 802.11ac.
Answer: High throughput, commonly used in office/home environments
>> Describe 802.11ax (Wi-Fi 6).
Answer: Designed for dense environments, low latency
>> The Ethernet standard was first developed by the IEEE. (True/False)
Answer: False. (It was originally developed by Xerox/PAR.)
>> refers to the geometric layout of the network.
Answer: Physical topology
>> A collision on a bus circuit means two computers transmitted at the time.
Answer: Same
>> The three latest common versions of Ethernet run at speeds of 1Gbps, 10Gbps, and 50 Gbps.
(True/False)
Answer: False. (The latest common speeds are 1Gbps, 10Gbps, and 100Gbps.)
>> 1000Base-LX is a version of 1000Base-T that runs on four pairs of CAT 5 cable. (True/False)
Answer: False. (1000Base-LX is fiber optic.)
>> A switch always broadcasts all packets it receives to all computers connected. (True/False)
Answer: False. (Switches learn MAC addresses and forward packets only to the destination port,
broadcasting only for unknown addresses or specific broadcast messages.)
