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. The application sends access logs from all locations to a single Amazon S3 bucket in uswest-2. To protect this sensitive data, the bucket policy is configured to deny access from public IP addresses. How should an engineer configure the network to meet these requirements?

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?

A.
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.

B.
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.

C.
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.

D.
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.
