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 uses AWS Network Firewall to protect outgoing traffic for multiple VPCs that are in the same AWS account. Each VPC contains Amazon EC2 instances that host the company's applications. Each EC2 instance is tagged with the name of the application it hosts. The EC2 instances are in Auto Scaling groups. A Network Firewall stateful rule group must remain up-to-date, even when an Auto Scaling group launches and terminates EC2 instances. Which solution will meet this requirement with the LEAST implementation and administrative effort? 

A consulting company manages AWS accounts for its customers. One of the company's customers needs to add intrusion prevention for its environment without having to re-architect the environment. The customer's environment includes five VPCs in two AWS Regions in the United States. VPC-to-VPC connectivity is achieved through VPC peering. The customer does not plan to increase the number of VPCs within the next 2 years. The solution must accommodate unencrypted traffic. Which solution will meet these requirements? 

An application team for a startup company is deploying a new multi-tier application into the AWS Cloud. The application will be hosted on a fleet of Amazon EC2 instances that run in an Auto Scaling group behind a publicly accessible Network Load Balancer (NLB). The application requires the clients to work with UDP traffic and TCP traffic. In the near term, the application will serve only users within the same geographic location. The application team plans to extend the application to a global audience and will move the deployment to multiple AWS Regions around the world to bring the application closer to the end users. The application team wants to use the new Regions to deploy new versions of the application and wants to be able to control the amount of traffic that each Region receives during these rollouts. In addition, the application team must minimize first-byte latency and jitter (randomized delay) for the end users. How should the application team design the network architecture for the application to meet these requirements? 

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?
