Students, please login to GMetrix to complete Exam #1 of the ITS - Networking Training Mode. You will screenshot every question with the correct answer and explanation to create a study guide for the certification exam you will later take in Certiport.

If you have not been certified in L2 and/or L3, you will use this study guide to practice while you are taking practice exams in GMetrix. You will login to GMetrix the same way you did in your FIT class with your CPS email address.

Lab Component - Installation Checklist [10 POINTS]:

☐ Insert microSD card into card reader
☐ Download correct OpenWrt image for Raspberry Pi 5
☐ Flash image to microSD card using Balena Etcher
☐ Connect Raspberry Pi 5 to MacBook using USB Ethernet adapter
☐ Powered on Raspberry Pi 5 and confirmed status LED lights
☐ Access 192.168.1.1 in a web browser to reach LuCI interface
☐ Set new root password successfully


Written Component - Discussion and Reflection Questions [10 POINTS]:
Why is it important to install an operating system like OpenWRT instead of using the Raspberry Pi without one?
How does OpenWRT change the way your Raspberry Pi communicates on a network compared to Raspbian OS?
What steps in the flashing and setup process must be done carefully to avoid configuration or connection issues?
Why is setting a new root password one of the first things you should do when accessing LuCI for the first time?
How could understanding how to install and access OpenWRT help you later when configuring real-world routers or network devices?

Form groups (Stations 1–4).
Label Raspberry Pi & Networking Station
Identify physical connections (Ethernet, power, Wi-Fi).
Create a labeled diagram or photo of the setup in the slideshow attached

4.6.4 How the Internet Works Video
4.6.5 Lab Activity: TCP Packet Handling [15 Points]

Lab Activity Part 2: (OSI Layers 4–7)  Lab Objective

In this lab, you will build a hands-on model to show how Internet data is organized, managed, and understood by people once it has "surfaced from the ocean."

Required Materials (Per Group)

Scissors (for cutting out depictions)
Glue sticks or tape (to attach cut-outs to the chart)
Markers or pens (for writing functions and examples on the chart)
Cut-out depictions of people, apps, data translators, sessions, and cargo (provided by teacher)
Group Chart: (provided by teacher)
Poster background with (provided by teacher)
Instructions
Get into your groups (3–4 students).
Each group will receive a set of cut-outs (icons, apps, people, translators, docks, containers).
The Internet has surfaced above the ocean.
Ships now unload their containers, people trade goods, and conversations happen across docks and markets.
These 4 layers represent how data is

On your chart, think of each row as:
Ensures cargo (data packets) is delivered correctly and reassembled.
Keeps conversations (sessions) open, managed, and closed properly.
Makes sure goods (data) can be understood — encryption, compression, file formats.
Where people actually use apps and services (browsers, email, games, IoT apps).
For each row:
Write what’s happening at this level in your own words.
Glue or place the cut-outs that fit this level (apps, file types, translators, TCP/UDP, etc.).
Answer these questions as a group:
Why do we need these 4 layers above the ocean if we already have cables, lanes, and ships below the ocean?
How does data get transformed from “signals” under the water into something humans can use (apps, videos, emails)?
Which layer feels most important for YOU as a user — and why?
Each group will share one example they matched and explain why it belongs at that “level above the ocean.”
Conclusion

This activity will help you see how the Internet isn’t just wires and signals — it’s also about Together with the first 3 layers, these 4 layers complete the story of how the Internet truly works.
