AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 98

A company's SAP solutions architect needs to design an architecture to deploy a highly available SAP S/4HANA application on AWS. The company requires the SAP NetWeaver ASAP ASCS components and the SAP HANA database components or the application to be highly available. The company will operate the SAP NetWeaver ASCS, SAP NetWeaver PAS, and SAP HANA database components on separate Amazon EC2 instances. Each EC2 instance will run the Red Hat Enterprise Linux operating system.

The company's AWS account has a VPC with a CIDR block that uses the 10.0.0.0/24 address block. The VPC contains two subnets. Each subnet is assigned to a different Availability Zone. The company has no other VPCs in this account, and the company has no other AWS accounts.

Which set of overlay IP addresses can the SAP solutions architect use to provide the required highly available architecture?

Answer options

• A. Two overlay IP addresses: 10.0.0.50 for SAP ASCS and 10.0.0.54 for SAP HANA
• B. Two overlay IP addresses: 192.168.0.50 for SAP ASCS and 192.168.0.54 for SAP HANA
• C. Three overlay IP addresses: 10.0.0.50 for SAP ASCS, 10.0.0.52 for SAP ERS, and 10.0.0.54 for SAP HANA
• D. Three overlay IP addresses: 192.168.0.50 for SAP ASCS, 192.168.0.52 for SAP ERS, and 192.168.0.54 for SAP HANA

Correct answer: D

Explanation

The correct answer is D because the 192.168.0.0/24 address range is not included in the VPC's CIDR block of 10.0.0.0/24, thus making it invalid. The other options either do not fully utilize the address space for high availability or fall outside the allowed IP range for the VPC. Therefore, only option D meets the requirements for creating a highly available architecture while remaining within the CIDR block constraints.
