According to Halsey and Ballew (2017), troubleshooting is critically essential to analyze various impending or upcoming issues properly within a specific networking system in concern.

In this assignment, the required specifics have been addressed with proper priority to each segment of necessary implementation and processing required for respective network design. This particular college requires separate network setups for the applicable Finance/HR, Academics, Library, Computer Lab and Classrooms. These services would be within a LAN infrastructure. Applicable processing of valid requirements is to be analyzed for the various procedures. As influenced by Bahry and Sugiantoro (2018), within an Additional Requirement, the application of specific Wireless Devices has been appropriated according to sufficient requirement within College students and respective staff. As a part of network administration and access to external services like the establishment of a connection with other networks or the internet, applicable insight has been provided for the requirement (, 2019). Four specific servers comprising of Domain Naming System server, Web Server, email server and file server have been provided.

This diagram would help in understanding the exact structure and requirements of devices to build this particular network. Within this system of approach, IP addresses are to be assigned within each of major networking system with the help of proper resolution within each IP range allocated for specific departments and workstations. Alves et al. (2018) have opined that this system needs to be observed for further development in future regarding physical network Infrastructure for processing the necessary requirements. Therefore, the address range allocated within the system needs to be designed with proper accommodation to a valid applicable scenario of processing.

Protocol model (, 2019)
An example of a reference model is the 7-
layer OSI or Open Systems Interconnection
model (Shimba, Mahenge and Sanga, 2017)
In this model respective Network Access layer
