When are free data transfers applicable across AWS? (Choose two)

Free inbound data transfer for EC2 instances is applicable because AWS does not charge for data that is transferred into their services. This applies to various AWS services, including EC2 instances. When data is uploaded to AWS from the internet or from other locations, it incurs no charges, which helps to facilitate the initial setup and ongoing operations of applications running in the AWS cloud.

Additionally, free outbound data transfer within the same region is also applicable. AWS allows free data transfer between services within the same region, meaning that resources can communicate and transfer data to each other without incurring charges. This is beneficial for applications that consist of multiple services that need to interact frequently, as it minimizes costs while maintaining efficient communication among those resources.

This structure encourages efficient architecture and cost-effective models, allowing users to fully leverage AWS services without the concern of incurring additional costs for data transfer, provided it's within the established parameters.
