Discuss the reasons you have chosen your particular configuration. Why did you choose DHCP addressing versus static IP addressing? In places where you lacked network connectivity, how did you extend coverage? What would you choose to do differently had you known what you know now?
What vulnerabilities do you think this network configuration will have? How could you improve security with added resources? What problems will this network layout encounter over time? How could this network layout be optimized?
How would you increase security for this network? How would you prevent MAC spoofing or man-in-the-middle attacks? Can a wireless network ever really be secure?
