AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 17

A company wants to migrate its SAP workloads to AWS from another cloud provider. The company’s landscape consists of SAP S/4HANA, SAP BW/4HANA, SAP Solution Manager, and SAP Web Dispatcher. SAP Solution Manager is running on SAP HANA.
The company wants to change the operating system from SUSE Linux Enterprise Server to Red Hat Enterprise Linux as a part of this migration. The company needs a solution that results in the least possible downtime for the SAP S/4HANA and SAP BW/4HANA systems.
Which migration solution will meet these requirements?

Answer options

• A. Use SAP Software Provisioning Manager to perform a system export/import for SAP S/4HANA, SAP BW/4HANA, SAP Solution Manager, and SAP Web Dispatcher.
• B. Use backup and restore for SAP S/4HANA, SAP BW/4HANA, and SAP Solution Manager. Reinstall SAP Web Dispatcher on AWS with the necessary configuration.
• C. Use backup and restore for SAP S/4HANA and SAP BW/4HANA. Use SAP Software Provisioning Manager to perform a system export/import for SAP Solution Manager. Reinstall SAP Web Dispatcher on AWS with the necessary configuration.
• D. Use SAP HANA system replication to replicate the data between the source system and the target AWS system for SAP S/4HANA and SAP BW/4HANA. Use SAP Software Provisioning Manager to perform a system export/import for SAP Solution Manager. Reinstall SAP Web Dispatcher on AWS with the necessary configuration.

Correct answer: D

Explanation

The correct answer is D because SAP HANA system replication allows for real-time data synchronization, which minimizes downtime during the migration of SAP S/4HANA and SAP BW/4HANA. Options A, B, and C involve methods that would require more downtime due to the need for complete system exports/imports or backups, which are not as efficient as replication for maintaining operational continuity.
