AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 70

A company wants to deploy SAP BW/4HANA on AWS. An SAP technical architect selects a u-6tb1.56xlarge Amazon EC2 instance to host the SAP HANA database. The SAP technical architect must design a highly available architecture that achieves the lowest possible RTO and a near-zero RPO. The solution must not affect the performance of the primary database.

Which solution will meet these requirements?

Answer options

• A. Deploy two u-6tb1.56xlarge EC2 instances for SAP HANA in separate AWS Regions. Set up synchronous SAP HANA system replication between the instances.
• B. Deploy two u-6tb1.56xlarge EC2 instances for SAP HANA in separate AWS Regions. Set up asynchronous SAP HANA system replication between the instances.
• C. Deploy two u-6tb1.56xlarge EC2 instances for SAP HANA in separate Availability Zones in the same AWS Region. Set up synchronous SAP HANA system replication between the instances.
• D. Deploy two u-6tb1.56xlarge EC2 instances for SAP HANA in separate Availability Zones in the same AWS Region. Set up asynchronous SAP HANA system replication between the instances.

Correct answer: C

Explanation

Option C is correct because deploying instances in separate Availability Zones within the same AWS Region allows for synchronous replication, achieving low RTO and near-zero RPO while maintaining performance. Options A and B involve different AWS Regions, which introduce latency and do not meet the near-zero RPO requirement. Option D, while in the same region, uses asynchronous replication, which does not provide the same level of data protection as synchronous replication.
