PAS-C01 Technology Practice Question
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.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure HANA replication to Amazon S3 for point-in-time recovery.
Why it's wrong here
S3 is for backup, not automatic failover.
- ✓
Set up HANA System Replication between two EC2 instances in different AZs with automatic failover.
Why this is correct
HANA System Replication across AZs provides high availability and automatic failover.
- ✗
Use HANA System Replication with a synchronous secondary in the same AZ.
Why it's wrong here
Does not protect against AZ failure.
- ✗
Deploy a single HANA database on a large EC2 instance in one AZ with regular backups to S3.
Why it's wrong here
Single point of failure, no automatic failover.

| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| 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 |
