Your company has many remote branch offices that need to communicate with each other as well as to connect with your AWS VPC. Which of the following can help achieve this connectivity in an easy manner?

Answer options:

A.VPN Cloudhub
B.AWS Direct Connect with a Public VIF
C.AWS Direct Connect with a Private VIF
D.VPC Peering

Answer – A
The AWS Documentation mentions the following.
Providing Secure Communication Between Sites Using VPN CloudHub
If you have multiple VPN connections, you can provide secure communication between sites using the AWS VPN CloudHub. This enables your remote sites to communicate with each other, and not just with the VPC. The VPN CloudHub operates on a simple hub-and-spoke model that you can use with or without a VPC. This design is suitable for customers with multiple branch offices and existing internet connections who`d like to implement a convenient, potentially low-cost hub-and-spoke model for primary or backup connectivity between these remote offices.
The following diagram shows the VPN CloudHub architecture with blue dashed lines indicating network traffic between remote sites being routed over their VPN connections.
Options B and C are incorrect since this is not ideal for Remote branch offices.
Option D is incorrect since this should be used to connect 2 VPCs.
