- A
Place the ASCS instance behind an Application Load Balancer and configure health checks.
Why wrong: ALB is for HTTP/HTTPS traffic, not for SAP ASCS which uses proprietary protocols.
- B
Configure an Auto Scaling group for the ASCS instance with a minimum of 1 and maximum of 2, and use a lifecycle hook to attach an Elastic IP.
Why wrong: Auto Scaling does not provide enqueue replication and may not achieve 15-minute RTO.
- C
Deploy a second ASCS instance in a different Availability Zone, set up SAP enqueue replication, and use a virtual IP address with Route 53 health checks for failover.
SAP's enqueue replication and multi-AZ deployment with DNS failover meets RTO and provides high availability.
- D
Enable CloudWatch EC2 Auto Recovery on the ASCS instance and configure it to start a new instance in a different AZ.
Why wrong: Auto Recovery only works within the same AZ, not cross-AZ.
Quick Answer
The answer is to deploy a second ASCS instance in a different Availability Zone, set up SAP enqueue replication, and use a virtual IP address with Route 53 health checks for failover. This configuration is correct because SAP enqueue replication synchronizes the lock table and message server state between the primary and secondary ASCS instances, enabling automatic failover without losing transactional data. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding that high availability for SAP Central Services requires application-level clustering across AZs, not just instance recovery. A common trap is choosing CloudWatch alarms to recover the instance, but that only restarts within the same AZ and ignores the enqueue state, failing the sub-15-minute RTO. Another trap is using an Auto Scaling group, which cannot manage SAP’s application state. Remember the mnemonic: “Replicate the queue, cross the zone, use a health-check throne” to recall enqueue replication, multi-AZ deployment, and Route 53 virtual IP for failover.
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 running SAP Business Suite on AWS. The system includes a central services (ASCS) instance, a primary application server (PAS), and a database server running SAP HANA. The company recently experienced an outage when the EC2 instance hosting the ASCS instance failed due to a hardware issue. The system was down for 4 hours while the IT team manually recovered the ASCS instance from an AMI. The company wants to implement a highly available ASCS instance with automatic failover and a Recovery Time Objective (RTO) of less than 15 minutes. The system is currently running in a single Availability Zone. What should the company do to meet these requirements?

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
Deploy a second ASCS instance in a different Availability Zone, set up SAP enqueue replication, and use a virtual IP address with Route 53 health checks for failover.
Option A is correct because SAP's enqueue replication and ASCS clustering across AZs with a virtual hostname provides automatic failover. Option B is wrong because ASG does not provide application-level clustering. Option C is wrong because CloudWatch recoveries only restart the instance in the same AZ, not cross-AZ, and does not handle enqueue state. Option D is wrong because ELB is not for ASCS failover.
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.
