Answer - B and C.
The AWS Documentation mentions the following.
AWS Direct Connect makes it easy to establish a dedicated network connection from your premises to AWS.
Using AWS Direct Connect, you can establish private connectivity between AWS and your datacenter, office, or colocation environment, which in many cases can reduce your network costs, increase bandwidth throughput, and provide a more consistent network experience than Internet-based connections.
You can connect your VPC to remote networks by using a VPN connection.

The two AWS services that help provide a connection from on-premises infrastructure to resources hosted in the AWS Cloud are:
B. AWS VPN: AWS VPN (Virtual Private Network) is a service that enables users to establish a secure and encrypted connection between an on-premises network and a VPC (Virtual Private Cloud) in AWS. With AWS VPN, users can securely access their resources in the cloud as if they were connected to their local network.
C. AWS Direct Connect: AWS Direct Connect is a service that provides a dedicated network connection between an on-premises network and AWS. It enables users to establish a private, high-bandwidth connection to AWS services, which can help reduce network costs, increase bandwidth throughput, and provide a more consistent network experience than Internet-based connections.
A. AWS VPC: AWS VPC (Virtual Private Cloud) is a service that allows users to create an isolated virtual network within AWS. While it doesn't directly provide a connection from on-premises infrastructure to resources hosted in the AWS Cloud, it can be used in conjunction with AWS VPN or AWS Direct Connect to provide a secure and isolated environment for resources in the cloud.
D. AWS Subnets: AWS Subnets are subdivisions of a VPC that allow users to segment their network into smaller, more manageable networks. While they don't directly provide a connection from on-premises infrastructure to resources hosted in the AWS Cloud, they can be used in conjunction with AWS VPN or AWS Direct Connect to create a more granular network topology in the cloud.
In summary, AWS VPN and AWS Direct Connect are the two services that directly help provide a connection from on-premises infrastructure to resources hosted in the AWS Cloud. AWS VPC and AWS Subnets can be used in conjunction with these services to provide a secure and isolated environment for resources in the cloud, as well as to create a more granular network topology.
