PAS-C01 Design of SAP Workloads on AWS Practice Question

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 has deployed SAP S/4HANA on AWS using a single EC2 instance for the HANA database and multiple EC2 instances for the application servers. The system is in production and the company wants to implement high availability for the HANA database to minimize downtime during patching and failures. The HANA database is critical and must have an RTO of less than 5 minutes and an RPO of zero. The current setup uses a single EBS volume for /hana/data and another for /hana/log. The company has two Availability Zones available. Which solution meets the requirements?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

A
Configure SAP HANA System Replication with automatic failover to a secondary HANA instance in another AZ.
Synchronous replication provides zero RPO and fast failover.
B
Attach the EBS volumes to two EC2 instances using EBS Multi-Attach.
Why wrong: Multi-Attach does not support cross-AZ.
C
Use AWS Backup to schedule snapshots every 5 minutes and restore in another AZ if needed.
Why wrong: Restore time exceeds 5 minutes; RPO >0.
D
Deploy the HANA database on a larger EC2 instance with higher availability SLA.
Why wrong: Instance SLA does not guarantee HA.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Configure SAP HANA System Replication with automatic failover to a secondary HANA instance in another AZ.

SAP HANA System Replication (HSR) with automatic failover meets the RTO < 5 minutes and RPO = 0 requirements by synchronously replicating data to a secondary HANA instance in another Availability Zone. Automatic failover ensures the secondary takes over without manual intervention, minimizing downtime during patching or failures. This is the only option that provides synchronous replication with zero data loss and fast failover across AZs.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may confuse EBS Multi-Attach with a cross-AZ solution, but Multi-Attach is strictly single-AZ and cannot provide the required cross-AZ high availability for SAP HANA.

Detailed technical explanation

How to think about this question

SAP HANA System Replication uses log-based synchronous replication (mode=sync) to ensure every committed transaction is written to both primary and secondary before acknowledgment, achieving RPO=0. Automatic failover is typically managed by a cluster manager like Pacemaker or the HANA host auto-failover feature, which monitors the primary and triggers a takeover within seconds. In practice, the RTO depends on the time to detect failure, promote the secondary, and mount the replicated data, which is well under 5 minutes when properly configured.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.

TExam Day Tips

Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

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.
