- A
Configure HANA replication to Amazon S3 for point-in-time recovery.
Why wrong: S3 is for backup, not automatic failover.
- B
Set up HANA System Replication between two EC2 instances in different AZs with automatic failover.
HANA System Replication across AZs provides high availability and automatic failover.
- C
Use HANA System Replication with a synchronous secondary in the same AZ.
Why wrong: Does not protect against AZ failure.
- D
Deploy a single HANA database on a large EC2 instance in one AZ with regular backups to S3.
Why wrong: Single point of failure, no automatic failover.
Question 1,694 of 1,733
PAS-C01 Technology 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. 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 migrating its SAP environment to AWS and wants to use SAP HANA as a Service on AWS (HANA database on AWS). The SAP application tier will run on EC2 instances behind an Application Load Balancer. The company requires high availability for the database with automatic failover in case of an AZ failure. Which architecture should the company implement?
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
✓
Set up HANA System Replication between two EC2 instances in different AZs with automatic failover.
Option B is correct because HANA System Replication configured between two EC2 instances in different Availability Zones (AZs) with automatic failover ensures high availability and resilience against an AZ failure. Option A is incorrect because replicating HANA to Amazon S3 is meant for backups and point-in-time recovery, not for real-time automatic failover. Option C is incorrect because synchronous replication within the same AZ does not protect against an AZ failure; it only provides protection against instance or host failure. Option D is incorrect because a single HANA database instance in one AZ, even with regular backups to S3, cannot provide automatic failover if the AZ fails; it would require manual recovery.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
