Which solutions will meet these requirements?

A company has its production VPC (VPC-A) in the eu-west-1 Region in Account 1. VPC-A is attached to a transit gateway (TGW-A) that is connected to an on-premises data center in Dublin, Ireland, by an AWS Direct Connect transit VIF that is configured for an AWS Direct Connect gateway. The company also has a staging VPC (VPC-B) that is attached to another transit gateway (TGW-B) in the eu-west-2 Region in Account 2.

A network engineer must implement connectivity between VPC-B and the on-premises data center in Dublin.

Which solutions will meet these requirements? (Choose two.)
A . Configure inter-Region VPC peering between VPC-A and VPC-B. Add the required VPC peering routes. Add the VPC-B CIDR block in the allowed prefixes on the Direct Connect gateway association.
B . Associate TGW-B with the Direct Connect gateway. Advertise the VPC-B CIDR block under the allowed prefixes.
C . Configure another transit VIF on the Direct Connect connection and associate TGW-B.
Advertise the VPC-B CIDR block under the allowed prefixes.
D . Configure inter-Region transit gateway peering between TGW-A and TGW-B. Add the peering routes in the transit gateway route tables. Add both the VPC-A and the VPC-B CIDR block under the allowed prefix list in the Direct Connect gateway association.
E . Configure an AWS Site-to-Site VPN connection over the transit VIF to TGW-B as a VPN attachment.

Answer: B,D

Explanation:

These solutions provide the necessary connectivity between VPC-B and the on-premises data center by associating TGW-B with the Direct Connect gateway and configuring inter-Region transit gateway peering between TGW-A and TGW-B.
