Amazon VPC-to—Amazon VPC Connectivity Options VPC Peering Describes the AWS-recommended approach for connecting multiple Amazon VPCs within a region using the Amazon VPC peering feature. Software VPN Describes connecting multiple Amazon VPCs using VPN connections established between user-managed software VPN appliances running inside of each Amazon VPC. Software-to- Describes connecting multiple Amazon VPCs with a VPN connection established Hardware VPN between a user-managed software VPN appliance in one Amazon VPC and AWS- managed network equipment attached to the other Amazon VPC. Hardware VPN Describes connecting multiple Amazon VPCs, leveraging multiple hardware VPN connections between your remote network and each of your Amazon VPCs. AWS Direct Connect Describes connecting multiple Amazon VPCs, leveraging logical connections on customer-managed AWS Direct Connect routers.

The correct answer is D. Software-to-Hardware VPN is not used as a VPC to VPC connectivity option.

Explanation: VPC (Virtual Private Cloud) is an AWS service that allows users to create a virtual network within the AWS cloud infrastructure. VPC peering, software VPN, and AWS VPN CloudHub are three ways of establishing connectivity between two VPCs.

A. VPC Peering: This is a networking connection between two VPCs that enables users to route traffic between them using private IP addresses. VPC peering allows the sharing of resources between VPCs, and it doesn't require an internet gateway, VPN connection, or hardware device.

B. Software VPN: This is a method of establishing a secure and encrypted connection between two VPCs over the internet. It requires the installation of VPN software on instances in each VPC, which then establish the connection between the two VPCs.

C. AWS VPN CloudHub: This is a managed VPN service that allows users to connect multiple VPCs to a central hub VPC. The hub VPC acts as a single point of entry for all traffic going in and out of the connected VPCs.

D. Software-to-Hardware VPN: This is not a VPC to VPC connectivity option. Instead, it refers to a connection between an on-premises network and an AWS VPC. It requires the installation of VPN software on the on-premises network, which then connects to an AWS VPN gateway, a hardware device provided by AWS.

In summary, VPC peering, software VPN, and AWS VPN CloudHub are three ways of establishing connectivity between two VPCs. Software-to-Hardware VPN, on the other hand, is not used as a VPC to VPC connectivity option, but as a method of connecting an on-premises network to an AWS VPC.
