Answer: Amazon Virtual Private Cloud (Amazon VPC)

Amazon Virtual Private Cloud (Amazon VPC) allows you to provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways. **Key features of Amazon VPC:** - **Logical isolation**: Provides a private, isolated section of AWS cloud - **Custom IP address ranges**: You can choose your own IP address range - **Subnet creation**: Create public and private subnets - **Security controls**: Configure security groups and network ACLs - **Connectivity options**: Connect to on-premises networks via VPN or Direct Connect **Why other options are incorrect:** - **AWS VPN**: Used for secure connections between on-premises networks and AWS, not for creating isolated sections - **Availability Zones**: Physical data centers within a region, not logical isolation - **AWS Regions**: Geographic locations containing multiple Availability Zones, not logical isolation
