AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 55

A company wants to improve the RPO and RTO for its SAP disaster recovery (DR) solution by running the DR solution on AWS. The company is running SAP ERP Central Component (SAP ECC) on SAP HANA. The company has set an RPO of 15 minutes and an RTO of 4 hours.
The production SAP HANA database is running on a physical appliance that has x86 architecture. The appliance has 1 TB of memory, and the SAP HANA global allocation limit is set to 768 GB. The SAP application servers are running as VMs on VMware, and they store data on an NFS file system. The company does not want to change any existing SAP HANA parameters that are related to data and log backup for its on-premises systems.
What should an SAP solutions architect do to meet the DR objectives MOST cost-effectively?

Answer options

• A. For the SAP HANA database, change the log backup frequency to 5 minutes. Move the data and log backups to Amazon S3 by using the AWS CLI or AWS DataSync. Launch the SAP HANA database. For the SAP application servers, export the VMs as AMIs by using the VM Import/Export feature from AWS. For NFS file shares /sapmnt and /usr/sap/trans, establish real-time synchronization from DataSync to Amazon Elastic File System (Amazon EFS).
• B. For the SAP HANA database, change the log backup frequency to 5 minutes. Move the data and log backups to Amazon S3 by using AWS Storage Gateway File Gateway. For the SAP application servers, export the VMs as AMIs by using the VM Import/Export feature from AWS. For NFS file shares /sapmnt and /usr/sap/trans, establish real-time synchronization from AWS DataSync to Amazon Elastic File System (Amazon EFS).
• C. For the SAP HANA database, SAP application servers, and NFS file shares, use CloudEndure Disaster Recovery to replicate the data continuously from on premises to AWS. Use CloudEndure Disaster Recovery to launch target instances in the event of a disaster.
• D. For the SAP HANA database, use a smaller SAP certified Amazon EC2 instance. Use SAP HANA system replication with ASYNC replication mode to replicate the data continuously from on premises to AWS. For the SAP application servers, use CloudEndure Disaster Recovery for continuous data replication. For NFS file shares /sapmnt and /usr/sap/trans, establish real-time synchronization from AWS DataSync to Amazon Elastic File System (Amazon EFS).

Correct answer: D

Explanation

The correct answer is D because it utilizes SAP HANA system replication, which is suitable for the database's continuous data replication needs while addressing the specified RPO and RTO. Options A and B focus on backup strategies rather than real-time replication, which may not meet the recovery objectives efficiently. Option C, while it offers continuous replication, does not specify the necessary configurations for SAP HANA, making it less optimal in this scenario.
