Which of the following describes the default network ACL associated with new subnets in a VPC?

The default network ACL (Access Control List) associated with new subnets in a VPC (Virtual Private Cloud) is designed to allow all inbound and outbound traffic. This means that all traffic is permitted by default, which provides a simple configuration for users when they first create a subnet in their VPC.

This default behavior helps users get started quickly without needing to deal with complex configurations right away. Users can always modify the ACL to restrict or allow specific traffic as per their requirements later on.

It's important to note that while you can create more restrictive rules, the initial setup is intended to facilitate connectivity and experimentation, making it easier to test applications in the cloud.

The other options imply a more restrictive set of rules or configurations that do not represent the default state of the network ACLs when a new subnet is created in a VPC.
