+## Review the main points of the lab
+
+Congratulations on completing the lab. Here are the main takeaways for this lab. 
+
++ A virtual network is a representation of your own network in the cloud. 
++ When designing virtual networks it is a good practice to avoid overlapping IP address ranges. This will reduce issues and simplify troubleshooting.
++ A subnet is a range of IP addresses in the virtual network. You can divide a virtual network into multiple subnets for organization and security.
++ A network security group contains security rules that allow or deny network traffic. There are default incoming and outgoing rules which you can customize to your needs.
++ Application security groups are used to protect groups of servers with a common function, such as web servers or database servers.
