Quick Answer
The answer is Amazon Route 53, because it provides DNS-based failover routing combined with health checks to manage the floating IP address required for SAP ASCS high availability. In an SAP HA architecture, the ASCS instance relies on a virtual hostname that must automatically resolve to the healthy node after a failure; Route 53’s failover routing policy accomplishes this by directing traffic away from an unhealthy instance and toward the standby, effectively serving as a cloud-native floating IP manager without custom scripting. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of how to implement SAP HA patterns using native AWS services, often contrasting Route 53 with Elastic IPs—a common trap where candidates assume Elastic IPs are suitable, but they lack automatic reassignment without additional automation. Remember the mnemonic: “Route 53 routes around failure; Elastic IPs just sit there.”
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.
A company is migrating its SAP system to AWS and needs to ensure high availability for the SAP Central Services (ASCS/ERS) instance. The solution must support automatic failover in case of an instance failure. Which AWS service should be used to manage the floating IP address required for the SAP high availability setup?
Amazon Route 53
Route 53 with health checks and failover routing can manage floating IP via DNS.
Elastic IP address
Why wrong: Elastic IPs don't auto-failover without additional automation.
Amazon CloudFront
Why wrong: CloudFront is a CDN, not used for SAP HA failover.
AWS Global Accelerator
Why wrong: Global Accelerator provides static IPs but is not designed for SAP HA failover.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon Route 53
Amazon Route 53 with health checks and failover routing can be used to manage a DNS-based floating IP. Option B is correct. Elastic IP addresses are static public IPs but do not automatically reassign on instance failure without custom scripting. AWS Global Accelerator provides static IP addresses but is designed for traffic optimization, not SAP HA failover. Amazon CloudFront is a CDN service.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is deploying SAP NetWeaver on AWS and needs to configure high availability for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). The solution must use AWS native services. Which TWO actions should be taken?
mediumWhy A: Options B and D are correct: Use Amazon Route 53 with health checks for failover DNS routing; use an Elastic IP address for the virtual IP address that moves between instances. Option A is wrong: ELB is for HTTP/HTTPS; ASCS uses proprietary protocols. Option C is wrong: AWS Global Accelerator is for traffic routing, but not typically used for ASCS/ERS failover. Option E is wrong: AWS Direct Connect is for private connectivity, not high availability.
Variation 2. A company is running SAP on AWS and wants to ensure high availability for the SAP Central Services (ASCS) instance. They have two EC2 instances in different Availability Zones within a single AWS Region. Which AWS service should be used to automatically fail over the ASCS instance if the primary instance fails?
mediumWhy D: Option C is correct: Amazon Route 53 with health checks and failover routing policy can redirect traffic to the secondary ASCS instance. Option A is wrong: ELB is not suitable for ASCS because ASCS uses non-HTTP ports. Option B is wrong: AWS Auto Scaling does not handle failover of stateful services. Option D is wrong: AWS CloudFormation is for provisioning, not automatic failover.
