Exam question from Amazon's AWS Certified SAP on AWS - Specialty PAS-C01
Question #: 34
Topic #: 1
[All AWS Certified SAP on AWS - Specialty PAS-C01 Questions]

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?

  • 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).

Selected Answer: D
D meets all the requirements. A and B gets eliminated as they are talking about parameter change which is against the ask in question. Cloud endure is block level replication so can not guarantee consistency of DB. Hence C gets eliminated.

Selected Answer: D
D: The scenario mentions an RPO of 15 minutes and an RTO of 4 hours, so the company needs a disaster recovery solution that provides data replication to meet these objectives. The solution proposed in option D meets these requirements most cost-effectively. It includes SAP HANA system replication for the SAP HANA database, CloudEndure Disaster Recovery for the SAP application servers, and AWS DataSync for NFS file shares. This approach ensures the company can achieve the desired RPO and RTO without changing any existing SAP HANA parameters related to data and log backup for on-premises systems.

B. Changing the log backup frequency to 5 minutes ensures a lower RPO (Recovery Point Objective) by reducing the amount of potential data loss in the event of a disaster. Moving the data and log backups to Amazon S3 using AWS Storage Gateway File Gateway allows for cost-effective storage of the backups in a durable and scalable manner. Exporting the SAP application servers as Amazon Machine Images (AMIs) using the VM Import/Export feature enables their easy deployment in AWS in the event of a disaster, reducing the RTO (Recovery Time Objective). Establishing real-time synchronization from on-premises NFS file shares (/sapmnt and /usr/sap/trans) to Amazon EFS using AWS DataSync ensures that the data remains up to date in the target environment.

Selected Answer: D
it mentioned that "The company does not want to change any existing SAP HANA parameters that are related to data and log backup", A and B change the frequency of log backup, so not correct. For C, it does not mentioned clearly, normally SAP HANA DB need an EC2 instance to be installed for data replication, it does not mentioned EC2 instance size, so assume it will use normal instance type which is not cost efficient. So D is the better one , launch a smaller EC2 for hana DB and switch off preload.

Selected Answer: B
Its between A or B. B looks right because in A it mentions creating DB which probabaly is not required in DR scenario.

i think its A because in B it uses both file gateway and datasync agent. This requires 2 agents to be set up which is not cost effective.

it mentioned "The company does not want to change any existing SAP HANA parameters that are related to data and log backup ", so A and B should be not correct, I will choose D.
