Question
A company has an application VPC and a networking VPC that are connected through VPC peering. The networking VPC contains a Network Load Balancer (NLB). The application VPC contains Amazon EC2 instances that run an application. The EC2 instances are part of a target group that is associated with the NLB in the networking VPC. The company configures a third VPC and peers it to the networking VPC. The new VPC contains a new version of the existing application. The new version of the application runs on new EC2 instances in an application subnet. The new version of the application runs in a different Availability Zone than that original version of the application. The company needs to establish connectivity between the NLB and the new version of the application. Which combination of steps will meet this requirement? (Choose three.)
Options
- ARegister the new application EC2 instances with the NLB by using the instance IDs.
- BRegister the new application EC2 instances with the NLB by using instance IP addresses.
- CConfigure the NLB in the Availability Zone where the new application EC2 instances run.
- DConfigure the NLB to use zonal shift.
- EConfigure the network ACL for the application subnet in the new VPC to allow outbound
- FConfigure the network ACL for the application subnet in the new VPC to allow inbound

Explanation
Since the new application EC2 instances reside in a different VPC, the NLB must use IP addresses to register the instances. Instance IDs can only be used for targets within the same To handle traffic efficiently, the NLB must be configured in the Availability Zone where the new application EC2 instances are running. This ensures proper routing and load balancing for instances in that zone. The network ACL for the new application's subnet must allow both inbound and outbound traffic to facilitate communication between the NLB in the networking VPC and the application EC2 instances in the new VPC.
