work Topology:

The network topology will consist of the following components for each department:

Finance Department:

$$

$$ Router

$$ Core Switch

$$ Distribution Switches

$$ Access Switches

$$ Finance Servers $($Accounting$,$ Billing, Payroll$)$

$$ Finance PCs $($Accountants$,$ Financial Analysts$)$

$$

Marketing Department:

$$

$$ Router

$$ Core Switch

$$ Distribution Switches

$$ Access Switches

$$ Marketing Servers $($Website$,$ Email Marketing, CRM$)$

$$ Marketing PCs $($Marketers$,$ Graphic Designers$)$

$$

Research and Development $($R&D$)$ Department:

$$

$$ Router

$$ Core Switch

$$ Distribution Switches

$$ Access Switches

$$ R&D Servers $($Development$,$ Testing, Version Control$)$

$$ R&D PCs $($Developers$,$ Engineers, QA Testers$)$

$$

Human Resources $($HR$)$ Department:

$$

$$ Router

$$ Core Switch

$$ Distribution Switches

$$ Access Switches

$$ HR Servers $($Employee Database, Recruitment, Training$)$

$$ HR PCs $($HR Managers, Recruiters, Trainers

$$

$$

Customer Service Department:

$$

$$ Router

$$ Core Switch

$$ Distribution Switches

$$ Access Switches

$$ Customer Service Servers $($Ticketing System, Knowledge Base, Live Chat$)$

$$ Customer Service PCs $($Agents$,$ Supervisors$)$

$$

Addressing Table:

$$

We will use the following IP address scheme for the network:

$$

$$ Finance Department:$10\mathrm{.}10\mathrm{.}10\mathrm{.}0/24$

$$ Marketing Department:$10\mathrm{.}10\mathrm{.}20\mathrm{.}0/24$

$$ R&D Department:$10\mathrm{.}10\mathrm{.}30\mathrm{.}0/24$

$$ HR Department:$10\mathrm{.}10\mathrm{.}40\mathrm{.}0/24$

$$ Customer Service Department:$10\mathrm{.}10\mathrm{.}50\mathrm{.}0/24$

$$

Configuration and Verification:

$1.$Configure the network devices $($routers$,$ switches, servers, and PCs$)$ with appropriate IP addressing, VLANs, and security settings based on the addressing table.

$2.$Implement VLANs to segregate network traffic within each department and apply access control lists $($ACLs$)$ to control traffic flow and enhance security.

$3.$Configure routing protocols $($e$.$g$.,$ OSPF, EIGRP$)$ to facilitate inter$-$department communication and ensure optimal routing of traffic between departments.

$4.$Implement security measures such as firewalls, intrusion detection$/$prevention systems $($IDPS$),$ and encryption to protect against unauthorized access and cyber threats.

$5.$Verify connectivity by testing reachability between devices within the same department and across different departments to ensure seamless communication and access to shared resources
