Question 1 of 10

Question 1

Basic multiple choice Remembering

What is the primary purpose of computer networking?

To share resources and information

Correct

To limit communication between devices

To make devices operate independently

To enhance security by isolating computers

Explanation

The primary purpose of computer networking is to share resources and information between devices, enabling communication and collaboration.

Question 2

Basic multiple choice Remembering

Which of the following is a common method of connecting computers in a network?

Ethernet cables

Correct

Flash drives

DVD players

Smartphones

Explanation

Ethernet cables are a standard method for connecting computers in a network, allowing for reliable data transmission.

Question 3

Basic multiple choice Understanding

What device is typically used to connect multiple networks together?

Router

Correct

Switch

Modem

Repeater

Explanation

A router is used to connect multiple networks together, routing data between them.

Question 4

Basic multiple choice Understanding

What does the term 'IP address' refer to in networking?

A unique identifier for a device on a network

Correct

A type of network cable

A software application for networking

An internet access point

Explanation

An IP address is a unique identifier assigned to each device on a network, allowing them to communicate with each other.

Question 5

Basic multiple choice Remembering

Which of the following is NOT considered a topology in networking?

Star

Ring

Linear

Correct

Mesh

Explanation

While 'Star,' 'Ring,' and 'Mesh' are recognized topologies in networking, 'Linear' is not a standard term used to describe a network topology.

Question 6

Complex multiple choice Understanding

A company is expanding its operations and needs to establish a new office network that can handle increased traffic efficiently. Which of the following strategies would best optimize their network performance while minimizing latency for connected devices?

Implementing a star topology with a central switch to manage traffic effectively.

Correct

Using a bus topology to reduce the amount of cabling needed.

Relying solely on wireless connections to simplify the network setup.

Encouraging all devices to connect directly without a central management point to enhance speed.

Explanation

Implementing a star topology allows for better management of network traffic through a central switch, which can help reduce latency for all connected devices by minimizing collision domains. In contrast, a bus topology tends to have issues with data collisions as more devices are added, while a fully wireless setup may face interference and coverage issues, and a lack of central management can lead to inefficient communication between devices.

Question 7

Complex multiple choice Applying

A network administrator is troubleshooting a connectivity issue where several devices on the same network cannot communicate with each other. They discover that the devices are on the same subnet but have different IP addressing schemes. Which of the following corrective actions should the administrator prioritize first to resolve the issue?

Ensure all devices are assigned to the same subnet mask and IP address scheme.

Correct

Reboot all devices to refresh their network configurations.

Upgrade the hardware of the devices to improve connectivity.

Separate the devices into different VLANs to isolate the traffic.

Explanation

The priority should be to ensure that all devices are on the same subnet mask and IP addressing scheme, as this is essential for successful communication. If the devices are on differing schemes, they may not recognize each other as being part of the same network, leading to connectivity issues. Rebooting may temporarily clear configurations, upgrading hardware is unnecessary, and separating into VLANs could complicate the issue further without addressing the basic communication problem.

Question 8

Case based multiple choice Understanding

[Case Scenario] A small business owner, Sarah, recently decided to upgrade her office network to support remote work due to increased demand for flexibility. She has limited technical knowledge but understands the importance of reliable connectivity for her team. Sarah researched various network solutions and consulted with a local IT firm that recommended installing a router with advanced security features. However, during the installation phase, she couldn't understand why her new system required both a modem and the router. Question: Why does Sarah need both a modem and a router for her network setup?

A modem connects to the internet service provider, while the router distributes that connection to multiple devices.

Correct

A modem is used for wireless connections and a router is for wired connections only.

The modem boosts the signal strength, while the router filters internet traffic.

A modem allows devices to share files, while the router manages internet speeds.

Explanation

In this case, the correct understanding is that a modem serves as a bridge to connect to an ISP, whereas a router takes that internet connection and allows multiple devices to access it over a local network. This setup is essential for creating an efficient office environment where employees can work remotely.

Question 9

Case based multiple choice Understanding

[Case Scenario] During a network setup for his start-up, Mike is exploring different types of network topologies. He has come across bus, star, and ring topologies. Mike is particularly interested in the reliability and scalability of each topology as he wants to ensure that his network infrastructure can adapt to future growth. After analyzing the options, he seeks clarity on how each topology could impact his business operations. Question: Which topology would best suit Mike's needs if he prioritizes reliability and ease of troubleshooting?

Bus topology is best for its simplicity and low cost, making troubleshooting easier.

Star topology is ideal as it isolates each device, so if one fails, the rest remain operational.

Correct

Ring topology provides equal access to all devices, making it the most reliable option.

Star topology is too complex and costs significantly more, which may cause operational issues.

Explanation

In this scenario, Mike needs a reliable network that is easy to troubleshoot, making star topology the most suitable option. Its design allows for efficient isolation of issues, promoting business continuity and adaptability to changes as the company grows.

Question 10

Case based multiple choice Understanding

[Case Scenario] John manages a local café that offers free Wi-Fi to customers. Recently, he noticed a significant slowdown in network speed during peak hours. To address this problem, he examined his current setup which included a single router that serves the entire café. After consulting with a networking professional, he is wondering about the best approach to enhance his Wi-Fi performance without overwhelming his budget. Question: Based on John's situation, what measure could he take to improve his café's Wi-Fi performance effectively?

Install a more powerful router that can handle higher traffic volumes.

Correct

Increase the number of public IP addresses available to distribute traffic.

Set up a guest network with limited access to reduce the load on the main network.

Limit the number of devices that can connect to the Wi-Fi at the same time.

Explanation

For John's café, installing a more powerful router is the best option to enhance Wi-Fi performance. A robust router will provide better coverage and handle multiple simultaneous connections, significantly improving the customer experience during peak hours.
