Your Team Has Been Asked To Design a Lan For A Very Successful Cpa Fir

Your team has been asked to design a LAN for a very successful CPA firm with five departments in one building and a total of 560 employees. Currently, the firm has no networked computers, and it is open to any suggestions your team can offer. The firm does have a few requirements: It wants to make sure that it can easily expand its LAN in the future without exorbitant costs and moving a lot of equipment. Every department must have very fast access to the LAN. The LAN must remain up at all times. Must use Windows 7 operating system. As a team, determine what kind of LAN your team will design for this company. Deliverable Instructions: Devise and prepare a 5-6 page proposal. Use your group discussion board or group virtual classroom to discuss the approach your team will take. As a team, create a 1 page executive summary to summarize your design, and 3 to 5 page paper with diagrams about the detailed network design. Put them into one Word document. Please add your file.

Introduction

The design of a Local Area Network (LAN) for a burgeoning CPA firm with 560 employees across five departments presents both challenges and opportunities. The primary objectives are ensuring scalability for future expansion, maintaining high-speed access, guaranteeing network uptime, and adhering to the Windows 7 operating system environment. This comprehensive proposal articulates a robust LAN design that aligns with these goals, emphasizing scalability, reliability, security, and performance.

Network Design Overview

The proposed LAN architecture employs a hierarchical star topology with future-proofing features. Central to this design is a core switch connecting to departmental switches, each serving an individual department. This configuration provides high speed, ease of management, and scalability. The network incorporates redundant pathways and equipment to ensure continuous uptime, fulfilling the firm's requirement for an always-on network.

Key Components and Technologies

• Switching Infrastructure: Managed Gigabit Ethernet switches form the backbone, supporting high-speed data transfer essential for intensive accounting applications. The core switch handles inter-departmental traffic, with each department connected through its respective switch.
• Network Redundancy: To ensure 24/7 availability, redundant links between switches are implemented, using Spanning Tree Protocol (STP) to prevent loops and ensure seamless failover.
• VLAN Segmentation: Virtual LANs are utilized to isolate departmental traffic, enhance security, and improve network performance.
• Server Infrastructure: Centralized servers, including domain controllers, file servers, and application servers, are housed in a resilient server room with backup power supplies and cooling.
• Wireless Access: To accommodate mobile devices and flexible working environments, secure wireless access points (WAPs) are deployed, supporting standards compatible with Windows 7.

Scalability and Expansion

The design anticipates future growth by employing modular switches and scalable cabling infrastructure. Fiber optic cabling connects the core switch to departmental switches, providing high bandwidth and easier upgrades. The use of VLANs also simplifies adding new departments or services without disrupting existing operations.

Security Measures

Security is embedded through the deployment of VLANs, access control lists (ACLs), and centralized authentication mechanisms such as RADIUS or Active Directory services aligned with Windows 7. Physical security in the server room and network equipment closets is also ensured.

Implementation Plan

The implementation involves detailed site surveys, procurement of suitable hardware, phased deployment to minimize disruption, and extensive testing. Training staff on network usage and troubleshooting is planned to sustain system performance.

Conclusion

This LAN design offers a scalable, reliable, and secure solution tailored to the CPA firm's needs. It leverages current technologies to deliver high-speed access, ease of future expansion, and minimal downtime, all within a Windows 7 environment. Proper planning and execution of this design will facilitate the firm's continued growth and operational efficiency.
