| Network Type | Use Case |
|---|---|
| PAN | a) Connecting your phone to Bluetooth headphones |

| WAN | c) Office network connecting 20 computers |
Answers: PAN-a, LAN-c, WAN-b
Question 4 (3 points) Explain in your own words why network segmentation is important for business security. Provide one specific example.
Sample Answer: Network segmentation divides a network into separate sections to limit access and contain security breaches. For example, guest WiFi should be separated from employee computers so visitors can't access company files or servers, even if they connect to the network.
Section 2: IP Addresses and Communication (10 points)
Question 5 (3 points) Which of the following IP addresses would be appropriate for devices on a small office network?
a) 8.8.8.8 b) 192.168.1.100 c) 203.123.45.67 d) 127.0.0.1
Answer: b) 192.168.1.100
Question 6 (2 points) What is the difference between a private IP address and a public IP address?
Sample Answer: Private IP addresses (like 192.168.x.x) are used inside networks and can't be reached from the internet. Public IP addresses can be reached from anywhere on the internet and must be globally unique.
Question 7 (3 points) Your office network uses the IP range 192.168.1.0 with subnet mask 255.255.255.0. List three valid IP addresses that could be assigned to computers on this network.
Sample Answer: Any three addresses from 192.168.1.1 to 192.168.1.254 (excluding 192.168.1.0 and 192.168.1.255)
