Effective reading and writing skills are important in the field of Internetworking Technologies because they:
help professionals communicate technical information clearly and accurately.
allow users to avoid using any documentation.
make troubleshooting network issues unnecessary.
eliminate the need for teamwork in networking projects.
The components required for network and Internet communications include:
Devices, media, messages, rules, and services
Only devices and media
Messages and rules only
Devices, media, and messages only
Select the correct components required to meet a given network specification. Which of the following lists the components you would choose for a small office network?
Router, switch, wireless access point, computers, printer
Modem, firewall, gaming console, television
Server, mainframe, supercomputer, plotter
Repeater, hub, fax machine, scanner
Describe the purpose and basic operation of the protocols in the Open Systems Interconnection (OSI) and Transmission Control Protocol (TCP) models and their associated protocols.
The OSI and TCP models define layers and protocols for network communication, specifying how data is transmitted and received across networks.
The OSI and TCP models are used only for wireless communication and do not apply to wired networks.
The OSI and TCP models are hardware devices that manage network traffic.
The OSI and TCP models are encryption algorithms for securing data transmission.
Predict the path between two hosts across a network. Data travels from one computer to another in a network by:
passing through routers and switches based on network addressing and routing protocols
directly connecting via a cable without any intermediary devices
using only wireless signals without any network devices
sending data through the internet without any addressing or routing
What type of cable would you use to connect a switch to a computer?
Crossover cable
Coaxial cable
Fiber optic cable
Straight-through cable
Which of the following lists the correct steps involved in configuring a switch for the first time?
Connect to the switch, enter privileged EXEC mode, configure basic settings, save the configuration
Connect to the switch, install new hardware, run diagnostics, reboot the switch
Power off the switch, connect to the console, update firmware, disconnect from the console
Enter user EXEC mode, configure advanced routing protocols, save the configuration, restart the switch
The OSI model has 7 layers. Which layer is responsible for choosing the best path for data to travel through the network?
A. Physical
B. Data Link
C. Network
D. Transport
What is the main job of the Transport layer in the TCP/IP model?
Sends data as light or electricity
Makes sure data arrives correctly
Changes data into pictures and text
Translating web page code
The Application layer of the OSI model includes protocols like HTTP and FTP.
True
False
The OSI model has layers that each do a special job. Which layer is responsible for turning 1s and 0s into signals that travel over the cable or fiber?
Network
Physical
Data Link
Transport
If two computers on the same LAN send data to each other, which devices forward the data?
Router only
Switch
Firewall
ISP modem
Which part of a computer lets it connect to the network and send or receive data?

Which type of cable is usually chosen for fast connections between buildings that are far apart?
UTP
Fiber-optic
Coaxial
Wireless LAN
The color order of wires inside an Ethernet connector must follow T568A or T568B standards because:
It looks better
It keeps costs low
Which of the following is true about network cables?
Devices expect signals on the wrong pins
Devices expect signals on the correct pins
Devices expect signals on the correct pins
It keeps the wires cooler
Which of the following can cause poor network performance if installed incorrectly?
Loose RJ-45 connectors
Exceeding UTP length limits
Using twisted pairs in proper order
Bending fiber cables too sharply
A default gateway on a switch allows the switch to communicate outside its own network.
True
False
A switched virtual interface (SVI) on a switch is mainly used to:
Give the switch an IP address for management
Provide a physical connection for end devices
Power devices over Ethernet
Increase the switch’s speed
A technician reads a label that says “Cat 6 – 23 AWG – 350 MHz.” What does the “Cat” in Cat 6 cable tell you?
The color of the cable
The cable’s performance level
The size of the connector
The brand of the cable
A short written network diagram shows a PC → Switch → Router → Internet. Which device connects the LAN to the outside world?
Switch
Access Point
Patch Panel
Router
Which device connects multiple computers in the same network and sends data only to the correct device using MAC addresses?
Router
NIC
Switch
A computer
What role does a network interface card (NIC) play in a computer?
