- A
Amazon EC2 Auto Recovery
Auto Recovery can automatically recover an instance from hardware failure.
- B
AWS Global Accelerator
Why wrong: Global Accelerator is more for global traffic, not typically for HANA HA.
- C
Multi-AZ deployment of SAP HANA
Multi-AZ provides redundancy across Availability Zones.
- D
Amazon Route 53
Why wrong: Route 53 is DNS, can be used but not a core service for HANA HA.
- E
Elastic Load Balancing
ELB can distribute traffic to healthy application servers.
Question 1,139 of 1,733
AWS Services for SAP HANA High Availability
This PAS-C01 practice question tests your understanding of technology. 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.
Which THREE AWS services are commonly used to implement high availability for SAP HANA databases on AWS? (Choose three.)
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
✓
Amazon EC2 Auto Recovery
Amazon EC2 Auto Recovery is correct because it automatically recovers an impaired EC2 instance by restarting it on a new healthy host within the same Availability Zone, preserving the instance ID, private IP, and Elastic IP. For SAP HANA, this minimizes downtime by quickly restoring the database instance without manual intervention, though it does not protect against an entire Availability Zone failure.
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 often confuse DNS-based routing (Route 53) or global traffic acceleration (Global Accelerator) with direct database high availability mechanisms, but AWS expects you to recognize that SAP HANA HA relies on instance recovery, multi-AZ replication, and load balancing at the application layer, not just network-level traffic management.
Detailed technical explanation
How to think about this question
SAP HANA high availability on AWS typically combines EC2 Auto Recovery for host-level failures, Multi-AZ deployment with HANA System Replication (HSR) for synchronous or asynchronous data replication across Availability Zones, and Elastic Load Balancing (specifically Network Load Balancer) to distribute client connections to the active HANA instance. Under the hood, HSR uses log-based replication and can achieve Recovery Point Objective (RPO) of zero with synchronous mode, while the load balancer performs health checks on the HANA SQL port (3xx15) and automatically reroutes traffic during failover, ensuring minimal disruption.
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.
