Creating a new default VPC after the original one has been deleted can be efficiently accomplished through an API call or the AWS Management Console. AWS provides straightforward options to recreate a default VPC using built-in functionality.

When using the AWS Management Console, there is a specific option under the VPC dashboard that enables you to easily create a new default VPC with default configurations. This automated process ensures that you have all necessary components such as Internet Gateway and DHCP settings in place without needing manual intervention.

Using API calls, such as those provided by AWS SDKs or CLI tools, you can achieve similar results programmatically. This allows for quick recreation of the VPC using the powerful capabilities of AWS APIs. These methods stand out as the quickest because they leverage AWS's existing features designed for resource management, minimizing the time and complexity involved compared to rebuilding everything manually from scratch or relying on external support.

While CloudFormation can certainly be used to create a VPC, it involves more setup and importing complex configurations, making it less immediate. Contacting AWS support for restoration would also take more time while waiting for a response, and manually creating each component isn't as efficient or straightforward as using the built-in tools.
