Question 19

Your company just acquired a new company. You have two VPCs ?one is 172.31.0.0/16 and one is 10.111.0.0/16. The acquired company uses 10.111.0.0/16 for their VPC. Your VPC "A" has a group of 12 servers in the range 10.111.2.101 ?10.111.2.112. Their VPC "B" has 20 servers from 10.111.2.171 ?10.111.2.190. You need to access both VPCs from the 172.31.0.0/16 VPC "C". What is the best way to approach this problem?

From VPC C, create a peering connection and add a route to VPC A's peering connection for 10.111.2.96/27 and a route to VPC B's peering connection for 10.111.2.0/24.

From VPC C, create a peering connection and add a route to VPC A's peering connection for 10.111.2.96/28 and a route to VPC B's peering connection for 10.111.2.0/24.

From VPC C, create a peering connection and adjust the route tables to direct traffic to the individual servers by exact IP address of the servers.

Invest the money and change the CIDR of one of the VPCs since one VPC cannot be peered to two VPCs with the same CIDR block.

Question 20

A financial services company that has on-premises infrastructure has acquired a startup company that has an API that is deployed in the AWS Cloud. As part of the acquisition, the financial services company has deployed an AWS Direct Connect private VIF to establish IP connectivity between the on-premises data center and the AWS environment.

Initial IP connectivity testing and bidirectional DNS resolution testing are successful. However, when business users attempt to connect to the API. a network administrator discovers IP subnet overlap between the financial services company's existing network and the startup company's AWS deployment.

A network architect receives the following diagram that summarizes the situation:

What is the MOST operationally efficient solution to enable the connectivity?

Provision additional subnets with a non-overlapping IP range in the VP

Deploy NAT gateways. Configure the virtual private gateway's next hop to be the NAT gateway. Advertise the new subnet IP address ranges through Direct Connect.Configure the on-premises hosts to target the API endpoint through the API servers.

Deploy a Network Load Balancer (NLB) across the subnets. Configure the API endpoints in a target group that is associated with the NLAdvertise the new subnetIP address ranges through Direct Connect. Configure the on-premises hosts to target the API endpoint through the NLB.

Provision additional subnets with a non-overlapping IP range in a new VPDeploy a Network Load Balancer (NLB) across the subnets. Configure the API endpoints as targets by IP address in a target group that is associated with the NLB.Peer the two VPCs together, and relocate the virtual private gateway into the new VPAdvertise the new subnet IP address ranges through Direct Connect. Configure the on-premises hosts to target the API endpoint through the NLB.

Provision additional subnets with a non-overlapping IP range in the VPC. Deploy a Network Load Balancer (NLB) across the existing subnets. Configure the API endpoints in a target group that is associated with the NLB. Configure aVPC endpoint service that targets the newly created NLB, and deploy VPC endpoints into the new subnet. Advertise the new subnet IP address ranges through Direct Connect. Configure the on-premises hosts to target the API endpoint through the VPC endpoints.
