An organization has multiple applications running in VPCs across multiple AWS accounts. The network engineer has deployed a central VPC with a pair of software VPN instances that run IPSec tunnels with dynamic routing to VGWs of all application VPCs. This central VPC is connected to on-premises resources via a Direct Connect connection using a private VIF. What additional configuration is required to enable the applications in VPCs to communicate with each other and access onpremises resources?

A company is building a hybrid PCI-DSS compliant application that runs in the us-west-2 Region and on-premises.

Question 83

A space exploration company owns a series of telescopes that capture a large number of images and data of the night sky.

The images and data are processed on an application hosted on AWS Fargate in a target group assigned to an Application Load Balancer (ALB). The application is made available through the address https://space.example.com.

Scientists require another custom-built application hosted on several Amazon EC2 instances within an Auto Scaling group.

This application will be made available from the address https:// space.example.com/meteor. The company needs a solutionthat can automatically scale from a small number of requests overnight to a large number of requests for a future meteorshower.

What is the MOST operationally efficient solution that meets these requirements?

Update the existing target group with the new EC2 instances. Update the application's ALB by adding a listener rule that redirects /meteor to the newly added EC2 instances.

Create a new target group. Configure the Auto Scaling group of the EC2 instances to use the target group. Update the ALB by adding a listener rule that redirects /meteor to the new target group.

Create a Network Load Balancer (NLB). Configure the NLB to listen on two ports. Configure a target group for one port to deliver all IP traffic to the Auto Scaling group to process the custom images. Configure a target group for thesecond port to deliver all IP traffic to Fargate. Use path-based routing in the ALB to route traffic for the URL prefix /meteor to the first target group. Route all other paths to the second target group.

Place the ALB behind an Amazon CloudFront distribution. Create a Lambda@Edge function that parses the request URI and adds the path-pattern header with the IP addresses of the EC2 instances to any request for /meteor. Add alistener rule to the ALB that looks for the HTTP header and uses the IP addresses of the EC2 instances to forward the traffic.

Question 85

A company wants to migrate its production and development applications to the AWS Cloud across multiple VPCs in three AWS Regions: us-east-1 (N. Virginia), eu-west-1 (Ireland), and ap-southeast-1 (Singapore). The company needs a scalable solution that provides connectivity between all three Regions. The solution also must provide private connectivity to the company's on-premises data center in Northern Virginia.

Data that is transferred from on premises and data that is transferred between Regions must be encrypted in transit. The company requires predictable network performance and must minimize cost.

The company has initiated a solution by deploying a transit gateway with two route tables in each Region. One route table is for the production environment, and one route table is for the development environment. What else must the company do to meet its requirements with the LOWEST latency?

Deploy an AWS Direct Connect connection in us-east-1 and a public VIF to the on-premises data center. On each transit gateway, create a VPN attachment over the public VIF for the production and development route tables. Createtransit gateway peering connections to route traffic between Regions.

Deploy an AWS Direct Connect connection in us-east-1 and a transit VIF to the on-premises data center. Associate all transit gateways and the transit VIF with a different Direct Connect gateway. Create transit gateway peeringconnections to route traffic between Regions.
