Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 222 discussion

A retail company is migrating its on-premises application to the AWS Cloud. Currently, the company has two on-premises data center locations. One data center is on the east coast of the United States, and one data center is on the west coast.

Each data center hosts four database systems. The largest database system stores 500 GB of data. The data centers are interconnected by two 10 GbE circuits for data synchronization. Each data center has two separate 1 GbE upstream internet connections. The company plans to have eight total VPCs to service its multiple business units. Four VPCs will be in the us-east-1 Region, and four will be in the us-west-2 Region.

A network engineer needs to design a connectivity solution that allows VPC-to-VPC connectivity. The solution must also allow secure connections between the on-premises data centers and AWS during the migration process. The company expects spikes in traffic among the VPCs during database synchronization. The company wants to run the migration plan during one weekend and as soon as technically possible. The company also wants to minimize long-term operational and human resources costs.

Which combination of steps will meet these requirements? (Choose two.)
