[All AWS Certified SAP on AWS - Specialty PAS-C01 Questions]

A company wants to migrate its SAP ERP landscape to AWS. The company will use a highly available distributed deployment for the new architecture. Clients will access SAP systems from a local data center through an AWS Site-to-Site VPN connection that is already in place. An SAP solutions architect needs to design the network access to the SAP production environment.
Which configuration approaches will meet these requirements? (Choose two.)

A. For the ASCS instance, configure an overlay IP address that is within the production VPC CIDR range. Create an AWS Transit Gateway. Attach the VPN to the transit gateway. Use the transit gateway to route the communications between the local data center and the production VPC. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.
B. For the ASCS instance, configure an overlay IP address that is outside the production VPC CIDR range. Create an AWS Transit Gateway. Attach the VPN to the transit gateway. Use the transit gateway to route the communications between the local data center and the production VPC. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.
C. For the ASCS instance, configure an overlay IP address that is within the production VPC CIDR range. Create a target group that points to the overlay IP address. Create a Network Load Balancer, and register the target group. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.
D. For the ASCS instance, configure an overlay IP address that is outside the production VPC CIDR range. Create a target group that points to the overlay IP address. Create a Network Load Balancer, and register the target group. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.
E. For the ASCS instance, configure an overlay IP address that is outside the production VPC CIDR range. Create a target group that points to the overlay IP address. Create an Application Load Balancer, and register the target group. Create a static route on the production VPC to route traffic that is directed to the overlay IP address to the ASCS instance.

Selected Answer: BD

Overlay IP should be outside Prod VPC CIDR, thus A and C are eliminated. HA of ASCS uses Network load balancer and not application load balancer, so E is eliminated
