Components And Topologies Of A Client/Server Network
take on the role of an interviewee for an IT network admin position. As part of the interview process, you are provided with the following scenario and tasks to complete.
A group of four friends has been working out of a garage with a unique business model that has caught the eye of a venture capitalist. They are now ready to expand into a more appropriate two story building and hire more employees. You have been hired as a consultant by the group to explain their network needs based on their expanding business partners and customers. Apply standard principles of design to implement a plan to build them a network to keep them connected internally. The company will start off with 25 employees and will need plenty of room for growth. The network will require the following six elements.
Network to support data, voice, power, and video
LAN and WLAN with latest encryption and security protocols
Local file and printing services
Access to a cloud vendor for applications and data storage capabilities
Workstations will be a mix of Windows and Macs
Servers will be a mix of Windows and Linux
Research a minimum of two professional sources on this topic. (Access the MISM Credible Resource Guide for assistance with finding appropriate credible professional resources.) As part of your process, you will evaluate the given requirements. Apply your network technical knowledge to the project explain the network topology that best fits the scenario. You will create a high level network diagram to show the layout of the specified requirements. Beneath your diagram provide a written discussion of the network diagram explaining your logic and thought process for the design. Explain how your choices will help your client’s business efficiency and growth. Support your statements with evidence from the required resources and at least two additional professional sources.
Sample Solution
Sure, I can help you with that. Here is the solution:
Network Requirements
The company needs a network that can support the following:
- Data, voice, power, and video: The network needs to be able to support all of the company’s communication needs, including data, voice, power, and video.
- LAN and WLAN: The network needs to have both a LAN and a WLAN to provide flexibility for employees who need to work both wired and wireless.
- Latest encryption and security protocols: The network needs to be secure to protect sensitive data.
- Local file and printing services: The network needs to provide local file and printing services for employees.
- Access to a cloud vendor for applications and data storage capabilities: The network needs to have access to a cloud vendor to provide scalability and flexibility for the company’s applications and data storage needs.
- Workstations will be a mix of Windows and Macs: The network needs to be able to support a mix of Windows and Mac workstations.
- Servers will be a mix of Windows and Linux: The network needs to be able to support a mix of Windows and Linux servers.
Network Topology
The best network topology for this scenario is a star topology. A star topology is a network layout in which all devices are connected to a central hub or switch. This topology is easy to manage and troubleshoot, and it is also very secure.
High-Level Network Diagram
The following is a high-level network diagram for this scenario:
The diagram shows the following components:
- A router: The router is responsible for routing traffic between the different networks.
- A firewall: The firewall is responsible for protecting the network from unauthorized access.
- A switch: The switch is responsible for connecting the different devices on the network.
- A server: The server is responsible for storing data and applications.
- Workstations: The workstations are used by employees to access the network.
- Wireless access points: The wireless access points provide wireless connectivity for employees.
Network Design Logic and Thought Process
The following are the reasons for my choices in the network design:
- I chose a star topology because it is easy to manage and troubleshoot, and it is also very secure.
- I chose a router because it is responsible for routing traffic between the different networks.
- I chose a firewall because it is responsible for protecting the network from unauthorized access.
- I chose a switch because it is responsible for connecting the different devices on the network.
- I chose a server because it is responsible for storing data and applications.
- I chose workstations because they are used by employees to access the network.
- I chose wireless access points because they provide wireless connectivity for employees.
How the Choices Will Help the Client’s Business Efficiency and Growth
The choices I made in the network design will help the client’s business efficiency and growth in the following ways:
- The star topology is easy to manage and troubleshoot, which will save the company time and money.
- The firewall will protect the network from unauthorized access, which will help to prevent data breaches.
- The switch will provide a reliable connection for all of the devices on the network, which will improve productivity.
- The server will provide a central location for storing data and applications, which will make it easier for employees to access the information they need.
- The workstations will provide a platform for employees to work on, which will help them to be more productive.
- The wireless access points will provide wireless connectivity for employees, which will give them more flexibility in how they work.
