A company has set up hybrid connectivity between its VPCs and its on-premises data center. The company has the on-premises.example.com subdomain configured at its DNS server in the onpremises data center. The company is using the aws.example.com subdomain for workloads that run on AWS across different VPCs and accounts. Resources in both environments can access each other by using IP addresses. The company wants workloads in the VPCs to be able to access resources on premises by using the on-premises.example.com DNS names. Which solution will meet these requirements with MINIMUM management of resources?

A company is planning to migrate to AWS and use multiple VPCs in multiple AWS Regions. A network engineer must connect the eu-west-1 and eu-central-1 Regions to the company headquarters and branch office, respectively. The network engineer created a production VPC, named Prod A, with a CIDR block of 10.0.0.0. Prod A runs in an account in eu-west-1. The network engineer then created another production VPC, named Prod B, with a CIDR block of 10.1.0.0. Prod Ð’ runs in a different account in eu-central-1. The network engineer performed the following steps to try to achieve the required connectivity: 1. Created one transit gateway in each Region2. Shared and accepted the transit gateways with the production accounts in both Regions3. Configured the peering attachment between both transit gateways4. Attached both VPCs to the respective Region transit gateway5. Created both transit gateway route tables and associated the attachments with the route tables6. Configured a static route in both transit gateway route tables to send traffic to the remote VPC in the other Region7. Activated route propagation on the VPC route tables in each Region After the configuration, the network engineer tried to connect from Prod A to Prod B. However, the connection was unsuccessful. What should the network engineer do to achieve the required connectivity? 

A company runs workloads in multiple VPCs. The company needs to securely access a workload in one of the VPCs, named VPC-A, from an on-premises data center. A network engineer sets up an AWS Site-to-Site VPN connection to a transit gateway. The network engineer configures dynamic routing for the connection, and communication works properly. Recently, the owner of VPC-A added another CIDR range to the VPC. The VPC-A owner created workloads that use the additional CIDR range. The company's on-premises network is unable to reach the new workloads. The network engineer needs to resolve the network connectivity issue and ensure that connectivity will not be affected if additional VPC CIDR ranges are added to the VPC in the future. Which solution will meet these requirements with the MOST operational efficiency? 

A company has developed a web service for language translation. The web service's application runs on a fleet of Amazon EC2 instances that are in an Auto Scaling group. The instances run behind an Application Load Balancer (ALB) and are deployed in a private subnet. The web service can process requests that contain hundreds of megabytes of data. The company needs to give some customers the ability to access the web service. Each customer has its own AWS account. The company must make the web service accessible to approved customers without making the web service accessible to all customers. Which combination of steps will meet these requirements with the LEAST operational overhead? (Choose two.)
