Question 1: Virtual Technology Selection As a Computer Systems and Software Engineer, you need to design and implement a secured network and communication systems infrastructure using virtual technology. Here are the steps: 1. Choose Suitable Virtual Technology: (5 marks) o Consider options such as VMware, VirtualBox, or Hyper-V. o Justify your choice based on factors like performance, scalability, ease of management, and compatibility with existing systems. Question 2: System Implementation (10 marks) As a Senior Systems Information Engineer, you’ll implement the system based on the provided diagram. Here’s what you need to do: 1. Setup Environment: o Use either VMware Workstation or Hyper-V (hypervisor) to create the virtual environment. o Ensure seamless connectivity configurations. 2. System Components: o Windows Server Operating Systems with AD DS Services configuration. o Test the accurate functioning of the Active Directory Controller. o Set up one or two Windows client OS machines. o Install the Linux PfSense firewall Operating System. o Capture screen snapshots of key installation processes and the login screen with customized Username and Password. Question 3: Configure Firewall Software Router (10 marks) Configure the PfSense firewall to forward packets in and out of the network using the following network services: 1. Routing & DHCP: o Set up routing rules and DHCP services for IP address assignment. 2. TCP/UDP Traffic Forwarding: o Configure PfSense to forward relevant traffic between internal and external networks. 3. Allowing ICMP: o Enable ICMP (ping) requests for network diagnostics.
