IP addresses within the 192.168.10.0/24 are used. USQAcademy outsourced the implementation of the network to MiniNet. The IP address scheme was designed by MiniNet. After delivery, the network administrator of USQAcademy discovered that not all PCs can ping each other. a) (5 marks) PCs in the USQAcademy network can ping only some, but not all other PCs. MiniNet informed USQAcademy that they assigned IPv4 addresses in this way on purpose. List all PCs which PC1 can ping. List all PCs which PC2 can ping. Explain why MiniNet implemented the network in such a strange way. b) (10 marks) The network administrator of USQAcademy decided to enhance the network such that all PCs can ping each other while keeping the IP addresses and network masks assigned to PCs unchanged. List 4. Additional hardware required e.g. Add PC 10, Switch4, Router1. Any change(s) in the connections e.g. Connect Switch1, Switch2, and Switch 3 to Switch Any change(s) in the configuration file of the devices e.g. Use IPv6 addresses, enable trunking. (There is no need to list the exact command(s) for the changes.) Submit your answer as Q1.pdf.
