AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 13

A company wants to run SAP HANA on AWS in the eu-central-1 Region. The company must make the SAP HANA system highly available by using SAP HANA system replication. In addition, the company must create a disaster recovery (DR) solution that uses SAP HANA system replication in the eu-west-1 Region. As prerequisites, the company has confirmed that Inter-AZ latency is less than 1 ms and that Inter-Region latency is greater than 1 ms.
Which solutions will meet these requirements? (Choose two.)

Answer options

• A. Install the tier 1 primary system and the tier 2 secondary system in eu-central-1. Configure the tier 1 system in Availability Zone 1. Configure the tier 2 system in Availability Zone 2. Configure SAP HANA system replication between tier 1 and tier 2 by using ASYNC replication mode. Install the DR tier 3 secondary system in eu-west-1 by using SYNC replication mode.
• B. Install the tier 1 primary system and the tier 2 secondary system in eu-central-1. Configure the tier 1 system in Availability Zone 1. Configure the tier 2 system in Availability Zone 2. Configure SAP HANA system replication between tier 1 and tier 2 by using SYNC replication mode. Install the DR tier 3 secondary system in eu-west-1 by using ASYNC replication mode.
• C. Install the tier 1 primary system and the tier 2 secondary system in eu-central-1. Configure the tier 1 system in Availability Zone 1. Configure the tier 2 system in Availability Zone 2. Configure SAP HANA system replication between tier 1 and tier 2 by using SYNC replication mode. Install the DR tier 3 secondary system in eu-west-1. Store daily backups from tier 1 in an Amazon S3 bucket in eu-central-1. Use S3 Cross-Region Replication to copy the daily backups to eu-west-1, where they can be restored if needed.
• D. Install the tier 1 primary system in eu-central-1. Install the tier 2 secondary system and the DR tier 3 secondary system in eu-west-1. Configure the tier 2 system in Availability Zone 1. Configure the tier 3 system in Availability Zone 2. Configure SAP HANA system replication between all tiers by using ASYNC replication mode.
• E. Install the tier 1 primary system and the tier 2 secondary system in eu-central-1. Configure the tier 1 system in Availability Zone 1. Configure the tier 2 system in Availability Zone 2. Configure SAP HANA system replication between tier 1 and tier 2 by using SYNCMEM replication mode. Install the DR tier 3 secondary system in eu-west-1 by using ASYNC replication mode.

Correct answer: B, E

Explanation

The correct answers are B and E. Option B correctly uses SYNC replication mode for the intra-region setup while using ASYNC for the inter-region DR setup, which aligns with the latency requirements. Option E incorrectly specifies SYNCMEM, which is not a valid replication mode for SAP HANA, making it non-compliant with SAP HANA's replication methods.
