This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 planning to migrate its SAP HANA database to AWS. They require high availability with automatic failover in less than 30 seconds. Which AWS service should be used to meet this requirement?
Elastic Load Balancing
Why wrong: ELB is for HTTP/TCP traffic, not SAP HANA database connections.
AWS Direct Connect
Why wrong: Direct Connect is for dedicated network, not failover.
AWS Global Accelerator
Why wrong: Global Accelerator is for global traffic, not primary choice for database failover.
Amazon Route 53
Route 53 with failover routing can meet the sub-30-second failover requirement.
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 can be configured with health checks and DNS failover to automatically redirect traffic to a standby SAP HANA database in a different Availability Zone or region when the primary fails. With a low TTL (e.g., 5 seconds) and active-passive routing, failover can occur in under 30 seconds, meeting the high availability requirement.
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 Balancing
AWS Direct Connect
Why it's wrong here
Direct Connect is for dedicated network, not failover.
AWS Global Accelerator
Why it's wrong here
Global Accelerator is for global traffic, not primary choice for database failover.
Amazon Route 53
Why this is correct
Route 53 with failover routing can meet the sub-30-second failover requirement.

Common exam traps
The trap here is that candidates often confuse high-availability load balancing (ELB) with DNS-based failover (Route 53), assuming ELB can handle database failover, but ELB cannot redirect traffic to a standby database in a different AZ or region with sub-30-second failover timing.
Detailed technical explanation
Route 53 failover uses DNS resolution with health checks that monitor the primary database endpoint; when the health check fails, Route 53 immediately returns the IP of the standby endpoint. The failover time depends on the DNS TTL and health check interval—setting a TTL as low as 5 seconds and using a fast health check interval (e.g., 10 seconds) can achieve failover in under 30 seconds. In a real-world scenario, this is often combined with a multi-AZ SAP HANA deployment using HANA System Replication, where Route 53 routes clients to the active node.
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.
