Which of the following carries no charge in AWS? (Choose two)

Inbound data transfer is considered to carry no charge in AWS. When you transfer data into AWS services from the internet, there is no cost associated with that inbound data transfer. This is a standard practice in many cloud service providers as it encourages users to move their data into the cloud, facilitating a smoother onboarding process and enabling the adoption of cloud services without the concern of immediate costs for data ingestion.

Additionally, outbound data transfer also generally carries no charge up to a certain limit or within specific services. However, it is important to understand that while inbound data transfer is free, outbound data transfer is charged once you exceed certain thresholds or in specific scenarios depending on the AWS service in use.

Thus, the rationale for how inbound data transfer incurs no charges is a fundamental aspect of AWS's pricing model, allowing users to scale their cloud environments without incurring costs for moving data into AWS. This model can help users optimize their workflows and reduce barriers related to cloud adoption.
