A. B. C. D.Answer - C.
You will need 3 AWS Direct Connect connections.
3 of them will be for normal data transfer.
The fourth one will be a backup in case any connection fails.
All other options are incorrect because AWS VPN does not give consistent data transfers.

https://aws.amazon.com/answers/networking/aws-multiple-data-center-ha-network-connectivity/To transfer data from an on-premises Hadoop cluster to AWS, you need to have a reliable and high-speed network connection. The requirement for 3 consistent connections and 1 fault-tolerant connection for data transfer on AWS can be met in a few different ways. Let's look at each answer option to determine the best choice.
A. A single 1 Gbps AWS Direct Connect connection with an AWS VPN backup.
This option provides a single 1 Gbps connection to AWS Direct Connect with an AWS VPN backup. While this solution provides a fault-tolerant connection with VPN backup, it does not meet the requirement for 3 consistent connections for data transfer. Therefore, option A is not the best choice.
B. Two 1 Gbps AWS Direct Connect connections with an AWS VPN backup.
This option provides two 1 Gbps connections to AWS Direct Connect with an AWS VPN backup. This solution meets the requirement for 3 consistent connections for data transfer and also provides a fault-tolerant connection with VPN backup. Therefore, option B is a possible solution for this requirement.
C. Four 1 Gbps AWS Direct Connect connections including one with an AWS VPN backup.
This option provides four 1 Gbps connections to AWS Direct Connect, including one with an AWS VPN backup. While this solution provides more bandwidth than option B, it may not be necessary for the given requirement of 1Gbps to 1.5Gbps data transfer. Therefore, option C may be an over-engineered solution.
D. Two 1 Gbps AWS Direct Connect connections and two connections with AWS VPN backups.
This option provides two 1 Gbps connections to AWS Direct Connect and two connections with AWS VPN backups. While this solution meets the requirement for 3 consistent connections for data transfer and also provides a fault-tolerant connection with VPN backup, it may not be necessary to have two VPN backup connections. Therefore, option D may be an over-engineered solution.
Based on the given requirement, option B seems to be the best choice as it meets the requirement for 3 consistent connections for data transfer and also provides a fault-tolerant connection with VPN backup.
