A company wants to fine-tune a foundation model (FM) using AWS while ensuring that its data remains private and secure in the original AWS Region. Which combination of actions meets these requirements most cost-effectively? (Choose two.)

The Amazon Bedrock API allows fine-tuning foundation models without moving data out of the customer's AWS account or region, ensuring data privacy and security. This is a cost-effective solution as it leverages a managed service. AWS PrivateLink, when used with a Virtual Private Cloud (VPC), establishes private connectivity between your VPC and Bedrock, preventing data from traversing the public internet. This enhances security and can reduce data transfer costs compared to public endpoints. Hosting the model on-site with AWS Outposts is expensive and complex, not cost-effective. Hosting the Amazon Bedrock API on premises is not possible as Bedrock is a fully managed AWS service. Amazon CloudWatch logs and metrics are for monitoring, not for securing or fine-tuning models.
