ITNAA Q $3\mathrm{.}1$ Project $1$ "MediCare Solutions is a leading healthcare provider in South Africa, offering comprehensive medical services to its clients from its headquarters situated in a central area within the city. The institution operates various departments, including Medical Operations & Radiology Services $($MORS$),$ Emergency Medicine and Reporting $($EMR$),$ Patient Records Management $($PRM$),$Information Technology $($IT$),$ and Client Services $($CS$).$The network infrastructure at the headquarters currently relies on external IT service providers for maintenance. However, the senior management has strategically decided to internalize and manage their network infrastructure. The objective is to establish a Local Area Network $($LAN$),$ Wide Area Network $($WAN$),$ and a dedicated Server$-$Side site within the headquarters premises.This Server$-$Side site will house critical servers such as the DHCP server, DNS Server, Web Server, and Email Server.The envisioned network infrastructure aims to uphold the principles of the CIA triad $($Confidentiality$,$ Integrity, and Availability$)$ while being cost$-$effective. To ensure security and efficiency, a hierarchical model is proposed, involving Core routers specifically purchased for the headquarters. Each Core router will connect to separate subscribed Internet Service Providers $($ISPs$).$ Additionally, it's been mandated that each department within the headquarters operates on a distinct network segment within the local area network to maintain security and optimize network performance.As the newly appointed network security engineer, your responsibility is to design a robust network model that meets the management's requirements and complies with information security principles. This design should facilitate seamless communication among the different departments while safeguarding the confidentiality, integrity, and availability of crucial data and services within the headquarters of MediCare Solutions in South Africa.".You are to create an efficient and secure network that meets the specific requirements of the hospital as described in the scenario. Consider the following guidelines while designing and implementing the network:$1\mathrm{.}1$ Each department must reside within its own VLAN and distinct subnetworks.$(7$ Marks$)1\mathrm{.}2$ Utilize the base network $190\mathrm{.}128\mathrm{.}100\mathrm{.}0$ and implement subnetting to allocate adequate IP addresses for each department's use.$(8$ Marks$)1\mathrm{.}3$ The company network interfaces with static, public IP addresses $(195\mathrm{.}136\mathrm{.}17\mathrm{.}0/30)$ linked to two Internet service providers.$(6$ Marks$)1\mathrm{.}4$ Set up fundamental device configurations such as hostnames, console passwords, enable passwords, banners, and disable IP domain lookup.$(6$ Marks$)1\mathrm{.}5$ Establish inter$-$departmental communication via respective multilayer switches, configured for inter$-$VLAN routing.$(8$ Marks$)$You are required to submit a comprehensive network design as a PKT file, along with the necessary configuration commands for each networking device.
