Topic 1 Question 222
2 つ選択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?
Deploy one transit gateway and attach all VPCs to it. Update the transit gateway and VPC route tables to allow any VPC to connect to any other VPC.
Configure VPC peering between all the VPCs. Update the VPC route tables to allow connectivity.
Provision two AWS Direct Connect connections from two Direct Connect locations that serve us-east-1 and us-west-2 to provide connectivity between the data centers and AWS.
Provision one transit gateway VPN attachment for each data center to build connectivity between the on-premises data centers and AWS VPCs.
Provision one AWS Site-to-Site VPN connection for each data center and for each VPC to build connectivity between the on-premises data centers and AWS VPCs.

Voted solution CD doesn't work as does not provide VPC-VPC connectivity. A is hard out as VPC-TGW cross regional peering is impossible. Without A we can also eliminate D as A was the only one provisioning TGW. C and E both say between DCs and AWS so we are left with B for VPC-VPC (also keeping long term costs down) and either C or E for DC-AWS. C is generally better but slower to put in place whereas E gives us both faster deployment and secure connections for the migration. E should provide enough bandwidth to accomplish the migration during a weekend. If we assume the DCs go away post migration DX is even less interesting.

Since a single transit gateway cannot attach VPCs from different regions, option A is indeed incorrect.

A - to minimise the operational cost and handle traffic spike C - help the steady and low latency connection
