17.8.5 Module Quiz – Build a Small Network

Networking is the backbone of modern communication, enabling devices to share data, resources, and services seamlessly. If you’re studying networking fundamentals, you might encounter the 17.8.5 module quiz – build a small network​, which is often part of entry-level IT and Cisco Networking Academy (NetAcad) courses. This module is designed to test your knowledge of basic networking concepts, device configuration, and troubleshooting in a hands-on, practical way.

Whether you are preparing for the quiz, studying for certifications like CompTIA Network+ or Cisco CCNA, or simply curious about how small networks are built, this guide will walk you through everything you need to know.

What Is the 17.8.5 Module Quiz?

The 17.8.5 Module Quiz – Build a Small Network is a networking lab-style assessment included in some networking curricula, particularly Cisco’s IT Essentials or Introduction to Networking courses. Its goal is to reinforce practical networking skills rather than just theoretical knowledge.

In this module, students typically:

• Design and configure a small network topology (usually with two or three routers, switches, and a few PCs).

• Assign IP addresses, subnet masks, and gateways.

• Configure devices using command-line interface (CLI) commands.

• Verify connectivity using testing tools like ping or traceroute.

This quiz simulates real-world networking scenarios, making it a valuable stepping stone for beginners entering IT or networking careers.

Core Learning Objectives

The quiz tests multiple skills and concepts:

1. Basic Topology Design

   • How to plan and connect routers, switches, and end devices.

   • Understanding of physical connections using Ethernet cables, serial cables, and wireless links.

2. IP Addressing and Subnetting

   • Assigning static IPs to devices.

   • Understanding subnet masks and calculating usable IP ranges.

   • Setting up default gateways.

3. Device Configuration

   • Using a router or switch CLI to set hostnames, passwords, and interfaces.

   • Configuring VLANs (Virtual Local Area Networks) if required.

4. Testing and Troubleshooting

   • Verifying network connectivity using tools like ping.

   • Troubleshooting misconfigurations, bad cabling, or incorrect IPs.

Typical Network Setup in the Quiz

Although variations exist, here’s a typical example of what you might be asked to build:

• One router connected to a switch.

• Two or three PCs connected to the switch.

• Devices assigned to a private IP network (e.g., 192.168.1.0/24).

• The router serving as the default gateway.

• Simple security measures like setting console and enable passwords.

For example:

This setup ensures all devices can communicate with one another on the same local network.

Step-by-Step Guide to Building a Small Network

If you want to prepare for this quiz, follow these basic steps:

1. Plan Your Network

Draw a topology diagram before connecting devices. Identify:

• Which devices (router, switch, PCs) will be used.

• The type of cables required (Ethernet for PC-to-switch, console cables for configuring devices).

• The addressing scheme, including subnetting if necessary.

2. Physically Connect Devices

Use an Ethernet switch as the central hub for PCs and routers. Connect:

• Router’s GigabitEthernet port to the switch.

• PCs to the switch via Ethernet.
  This forms a star topology, the most common setup for small networks.

3. Configure the Router

Access the router CLI via console cable:

1. Assign a hostname:

   Router> enable
Router# configure terminal
Router(config)# hostname R1


2. Configure the router interface:

   R1(config)# interface g0/0
R1(config-if)# ip address 192.168.1.1 255.255.255.0
R1(config-if)# no shutdown


4. Configure PCs

On each PC, manually assign IP addresses, subnet masks, and gateways through the network settings.
For example:

• PC1: IP 192.168.1.10, Gateway 192.168.1.1

• PC2: IP 192.168.1.20, Gateway 192.168.1.1

5. Test Connectivity

Use the ping command from each PC to test connectivity:

If all pings succeed, your small network is functioning correctly.

6. Troubleshoot If Needed

If devices can’t communicate:

• Check cabling and port LEDs.

• Verify IP addresses and subnet masks.

• Ensure the router interface is enabled.

• Review firewall or antivirus settings that may block traffic.

Why This Module Matters

The 17.8.5 Module Quiz isn’t just an academic exercise; it builds foundational skills for IT professionals. Here’s why it’s important:

1. Hands-On Experience
   Networking knowledge isn’t purely theoretical. Being able to design and troubleshoot a network is crucial for IT jobs.

2. Prepares You for Certification
   The skills covered align closely with CompTIA Network+ and Cisco CCNA exam objectives.

3. Real-World Application
   Small office/home office (SOHO) networks often resemble this setup, giving students real-world confidence.

4. Logical Thinking and Problem Solving
   Network building encourages structured thinking and step-by-step troubleshooting, both essential in tech careers.

Tips for Success on the Quiz

• Practice subnetting problems before attempting the quiz.

• Familiarize yourself with Cisco Packet Tracer, a simulation tool widely used for labs.

• Memorize essential CLI commands for routers and switches.

• Approach troubleshooting systematically—start with cables, then IP settings, and finally device configurations.

Conclusion

The 17.8.5 module quiz – build a small network​ is an excellent introduction to practical networking. It combines theoretical knowledge with hands-on practice, preparing students for real-world IT environments. By planning a network, configuring devices, and troubleshooting errors, you’ll gain the skills needed to design and maintain functional networks confidently.

If you’re preparing for this quiz, spend time practicing on simulation platforms, reviewing core commands, and understanding how devices communicate. With consistent practice, you’ll not only ace the quiz but also lay a strong foundation for your networking career.
