You are working in a financial company, and you need to establish the network connections between on-premises data centers and AWS VPCs. The connectivity needs to be secure with IPsec connections. A predictable and high-performance network is also required over private lines. Which of the following methods would you select?

Answer options:

A.AWS Direct Connect + VPN
B.AWS Managed VPN
C.AWS Direct Connect
D.Software VPN

Correct Answer – A
AWS has provided several connectivity options, according to https://d1.awsstatic.com/whitepapers/aws-amazon-vpc-connectivity-options.pdf. VPN is needed as it creates an IPsec connection. AWS Direct Connect is also required because it establishes a private connection with high bandwidth throughput.
Option A is CORRECT: Because with AWS Direct Connect + VPN, you can create IPsec-encrypted private connections.
Option B is incorrect: Because only with VPN, the network performance cannot be guaranteed.
Option C is incorrect: Because AWS Direct Connect does not use IPsec protocol.
Option D is incorrect: Because Software VPN is still based on the internet instead of a dedicated network.
