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 plans to migrate their SAP HANA database to AWS. They require the highest availability with automatic failover in case of an AZ failure. Which architecture should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Multi-AZ with HANA System Replication in sync mode and automatic failover.
Option A is correct because it meets the requirement for highest availability with automatic failover in case of an AZ failure. HANA System Replication (HSR) in synchronous mode ensures zero data loss (RPO=0) by committing transactions only after they are replicated to the standby, and when combined with Multi-AZ deployment, it provides automatic failover across Availability Zones. This architecture is the AWS-recommended pattern for SAP HANA high availability, leveraging the AWS Multi-AZ concept with HSR's built-in automatic takeover capability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Multi-AZ with HANA System Replication in sync mode and automatic failover.
Why this is correct
Provides automatic failover across AZs.
Related concept
Read the scenario before looking for a memorised answer.
✗
Single AZ with HANA System Replication to a standby in the same AZ.
Why it's wrong here
Does not protect against AZ failure.
✗
Single AZ with daily backups to Amazon S3.
Why it's wrong here
Backup & Restore has high RTO, not automatic.
✗
Multi-AZ with HANA System Replication in async mode and manual failover.
Why it's wrong here
Manual failover is not automatic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'high availability' with 'disaster recovery' and select a backup-only option (C) or a Single AZ option (B), failing to recognize that automatic failover across AZs requires both Multi-AZ deployment and synchronous replication with automated takeover.
Detailed technical explanation
How to think about this question
HANA System Replication in synchronous mode uses a log shipping mechanism where the primary waits for acknowledgment from the secondary before committing a transaction; this ensures zero data loss but introduces latency proportional to network round-trip time. In a Multi-AZ setup on AWS, the typical latency between AZs in the same region is under 2 ms, making synchronous replication feasible for most SAP workloads. The automatic failover is handled by HANA's own HA/DR provider (e.g., pacemaker or HANA's built-in takeover) or by AWS services like Amazon Route 53 health checks combined with custom scripts, but the key is that the failover is triggered without human intervention.

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
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
