AWS Technical Essentials Practice

The purpose of an AWS Virtual Private Cloud (VPC) is to provision a secure, isolated section of the AWS cloud where users can define and control their own virtual network. This includes configuring IP address ranges, subnets, route tables, network gateways, and security settings to create a customized network environment that meets specific application and security requirements.

Creating a VPC enables users to extend their on-premises networks into the cloud securely and provides a platform for launching various AWS resources in a controlled environment. This isolation ensures that resources within the VPC can be protected from outside access, while still allowing communication between them and controlled access to the internet or other AWS services as needed.

The other options presented do not accurately describe the main purpose of a VPC. While databases might require backup solutions, monitoring of usage and billing pertains to AWS account management, and preventing unauthorized access relates more to security measures within the context of networking, they do not encapsulate the core functionality of a VPC, which is focused on network segmentation and control.
