Case Study $1$

The initial portfolio file is a LAN at a business. The LAN consists of two fast switches $($Distrib$1$ and Distrib$2),$ three switches for end$-$devices $($Access$1,$ Access$2$ and Access$3)$ and one router which is used to separate broadcast domains. The end$-$devices are broken into two main subnets: Human Resources $($HR$)$ and Sales. Each subnet has a number of PCs and one workgroup server. A diagram of the LAN is shown below.
