Quick Answer
The answer is Amazon Route 53 health checks with failover routing. This configuration provides high availability for SAP ASCS by continuously monitoring the primary ASCS instance and automatically redirecting traffic to a secondary, standby ASCS in a different Availability Zone if the primary fails. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that SAP ASCS is a stateful, single-point-of-failure service that cannot be load-balanced with an Elastic Load Balancer, which is a common trap—ELB is designed for stateless web tiers, not for the active-passive architecture required by SAP Central Services. Auto Scaling handles compute elasticity, not failover, and CloudFront is a CDN for content delivery. The key memory tip is to associate ASCS with active-passive failover, not active-active load balancing: think “ASCS = Route 53 failover, not ELB.”
This PAS-C01 practice question tests your understanding of migration. 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.
A company wants to migrate its SAP application to AWS and needs to ensure high availability for the SAP Central Services (ASCS). Which AWS feature should be used to achieve this?
Elastic Load Balancer (ELB)
Why wrong: ELB is not typically used for ASCS; Route 53 is more appropriate.
Auto Scaling groups
Why wrong: Auto Scaling is for horizontal scaling, not HA for stateful services like ASCS.
Amazon Route 53 health checks with failover routing
Route 53 can monitor ASCS health and failover to a standby instance.
Amazon CloudFront
Why wrong: CloudFront is a CDN for content delivery, not for HA.

Correct answer & explanation
Amazon Route 53 health checks with failover routing
Amazon Route 53 with health checks and failover routing can redirect traffic to a secondary ASCS in case of failure, providing high availability. Option B (Auto Scaling) is for compute scaling, not HA. Option C (ELB) is for load balancing but not typically used for ASCS. Option D (CloudFront) is a CDN.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Elastic Load Balancer (ELB)
Why it's wrong here
ELB is not typically used for ASCS; Route 53 is more appropriate.
Auto Scaling groups
Why it's wrong here
Auto Scaling is for horizontal scaling, not HA for stateful services like ASCS.
Amazon Route 53 health checks with failover routing
Why this is correct
Route 53 can monitor ASCS health and failover to a standby instance.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
