You are a network engineer working for Pace Seven IT Network Solutions. Your manager has tasked you with designing a network for a client's building, which has offices and a data center both located on the same floor.

Design a network and a data centre reading carefully the specifications and using the floor plans below:

Room $6$ should house the communications equipment and a data centre.

Each office is equipped with $7$ desktop PCs$,$ all of which operate critical functions.

Most network devices should be located in room $6,$ where they will need racks. No rack can be installed in any other room.

The LAN must be $100\%$ redundant to ensure no single point of failure; in the event one circuit fails, another must remain operational. This requirement must be addressed in the design documentation.

The network diameter is not a concern.

The design must include all three layers of the hierarchical model covered in the lectures.

At this stage of the project, there is no need for any configuration of the devices.

While cost is not a primary concern, appropriate equipment selection is essential; for example, use an enterprise$-$class router instead of a carrier$-$class router, or a $24-$port switch instead of a $48-$port switch, as needed.

Consideration of future scalability is required and must be addressed in the documentation.

Describe the equipment necessary for your LAN to support $2$x$10$ Gbps connections to $2$ ISP provider routers, excluding any equipment at the ISP site.

It is unnecessary to detail software requirements, such as operating systems or virtualization technologies, at this stage of your development.
