Your company currently has the following requirement.
Transfer of data from an on-premises Hadoop cluster to AWS.
The transfer of data can run from 1Gbps to 1.5Gbps.
The requirement for 3 consistent connections and 1 fault-tolerant connection for data transfer on AWS.
Which of the following would you incorporate?

Answer options:

A.A single 1 Gbps AWS Direct Connect connection with an AWS VPN backup.
B.Two 1 Gbps AWS Direct Connect connections with an AWS VPN backup.
C.Four 1 Gbps AWS Direct Connect connections including one with an AWS VPN backup.
D.Two 1 Gbps AWS Direct Connect connections and two connections with AWS VPN backups.

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.
