This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is planning to run SAP NetWeaver on AWS and needs to ensure high availability for the database layer. Which AWS service can be used to achieve automatic failover of an SAP HANA database?
AWS Database Migration Service (DMS)
Why wrong: DMS is for migration, not high availability.
Application Load Balancer (ALB)
Why wrong: ALB is for distributing HTTP traffic, not for database failover.
Amazon RDS Multi-AZ
Why wrong: RDS Multi-AZ is for Amazon RDS databases, not SAP HANA.
SAP HANA System Replication (HSR)
HSR provides synchronous replication and automatic failover for HANA.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
SAP HANA System Replication (HSR)
SAP HANA System Replication (HSR) is the native SAP mechanism for replicating data from a primary HANA database to one or more secondary systems, enabling automatic failover in the event of a primary failure. This is the correct approach for achieving high availability for SAP HANA on AWS, as it integrates with AWS services like Elastic IPs or Route53 for IP re-mapping during failover, and is fully supported by SAP for production workloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Database Migration Service (DMS)
Why it's wrong here
DMS is for migration, not high availability.
Application Load Balancer (ALB)
Why it's wrong here
ALB is for distributing HTTP traffic, not for database failover.
Amazon RDS Multi-AZ
Why it's wrong here
RDS Multi-AZ is for Amazon RDS databases, not SAP HANA.
SAP HANA System Replication (HSR)
Why this is correct
HSR provides synchronous replication and automatic failover for HANA.

Common exam traps
The trap here is that candidates may confuse Amazon RDS Multi-AZ (which provides automatic failover for managed databases) with SAP HANA's own replication mechanism, not realizing that SAP HANA is not a supported engine for RDS and must be self-managed on EC2.
Detailed technical explanation
SAP HANA System Replication uses either synchronous or asynchronous replication modes, with the 'synchronous in-memory' mode ensuring zero data loss by committing transactions only after acknowledgment from the secondary node. In AWS, a common architecture uses a secondary HANA instance in a different Availability Zone, with an Elastic IP or a Network Load Balancer (NLB) configured to redirect client traffic upon failover, often automated via AWS Lambda or custom scripts. A subtle behavior is that HSR requires the same SID and instance number on both nodes, and the secondary must be in 'recovery' mode until failover, which can impact monitoring and backup strategies.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
