Exam question from Amazon's AWS Certified SAP on AWS - Specialty PAS-C01

Question #: 3
Topic #: 1

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

A company hosts its SAP NetWeaver workload on SAP HANA in the AWS Cloud. The SAP NetWeaver application is protected by a cluster solution that uses Red Hat Enterprise Linux. High Availability Add-On. The cluster solution uses an overlay IP address to ensure that the high availability cluster is still accessible during failover scenarios.
An SAP solutions architect needs to facilitate the network connection to this overlay IP address from multiple locations. These locations include more than 25 VPCs, other AWS Regions, and the on-premises environment. The company already has set up an AWS Direct Connect connection between the on-premises environment and AWS.
What should the SAP solutions architect do to meet these requirements in the MOST scalable manner?

A. Use VPC peering between the VPCs to route traffic between them.
B. Use AWS Transit Gateway to connect the VPCs and on-premises networks together.
C. Use a Network Load Balancer to route connections to various targets within VPCs.
D. Deploy a Direct Connect gateway to connect the Direct Connect connection over a private VIF to one or more VPCs in any accounts.

I will also go with Option B. 1. It is not a transit, it is a private VIF which is provided in the answer 2. Private vif can connect only to 1 VPC at a time in a single region. 3. You would need 25 vifs to connect to 25 VPC's. Hence Option B is correct

Correct B. AWS Transit Gateway is a network transit hub that can interconnect thousands of VPCs and on-premises networks through a central gateway. This simplifies the network architecture and eliminates the need for complex peering relationships. AWS Transit Gateway also supports inter-Region peering, which enables the connection of transit gateways across different AWS Regions using the AWS global network. This way, the SAP NetWeaver workload on SAP HANA can be accessed from multiple locations with high performance and security.
