- A
Set up HANA System Replication with synchronous replication to a secondary instance in us-east-1b and configure automatic takeover.
Correct. HANA System Replication with synchronous mode across AZs provides automatic failover, meeting both RPO and RTO.
- B
Take EBS snapshots every 15 minutes and copy them to another region.
Why wrong: Incorrect. EBS snapshots taken every 15 minutes cannot guarantee RPO and RTO due to snapshot consistency delays and restore time exceeding 30 minutes.
- C
Move the HANA database to a larger instance in the same Availability Zone and increase IOPS to 10000.
Why wrong: Incorrect. Moving to a larger instance with more IOPS in the same AZ does not protect against AZ failure; the single point of failure remains.
- D
Migrate the HANA database to Amazon RDS for SAP HANA with Multi-AZ enabled.
Why wrong: Incorrect. Amazon RDS does not support SAP HANA; HANA must be self-managed on EC2. Multi-AZ option is not available.
PAS-C01 HANA System Replication Practice Question
This PAS-C01 practice question tests your understanding of technology. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: hANA System Replication. 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 runs its SAP ERP system on AWS. The SAP application servers are in an Auto Scaling group across two Availability Zones. The SAP HANA database runs on a single EC2 instance in us-east-1a. The database instance has an Elastic IP and uses EBS io1 volumes with 5000 provisioned IOPS. During a recent deployment, the company experienced a complete outage when the Availability Zone us-east-1a became unavailable due to a power failure. The database was unavailable for 6 hours until the zone recovered. The company wants to implement a highly available architecture that can automatically recover from an AZ failure with minimal data loss. The Recovery Point Objective (RPO) is 15 minutes and Recovery Time Objective (RTO) is 30 minutes. What should the company do?

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
Set up HANA System Replication with synchronous replication to a secondary instance in us-east-1b and configure automatic takeover.
Option A is correct because HANA System Replication with synchronous replication to a secondary instance in a different Availability Zone (us-east-1b) provides automatic takeover, meeting the RPO of 15 minutes (synchronous replication ensures no data loss) and RTO of 30 minutes (automatic failover). Option B is wrong because EBS snapshots every 15 minutes cannot guarantee RPO and RTO; restore time from snapshots often exceeds 30 minutes, and cross-region copying adds latency. Option C is wrong because scaling within the same AZ does not address AZ failure; the single point of failure remains. Option D is wrong because Amazon RDS for SAP HANA does not exist; HANA is not supported on RDS. The correct architecture requires HANA System Replication across AZs.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates may mistakenly think that RDS Multi-AZ is available for SAP HANA, but HANA is not a supported engine on Amazon RDS. HANA must be managed on EC2 with HANA System Replication.

How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- HANA System Replication
- Recovery Point Objective (RPO)
- Recovery Time Objective (RTO)
- Multi-AZ deployment
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
HANA System Replication
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.
