An organization is planning to migrate its SAP landscape to AWS and needs to ensure high availability for the SAP Central Services (ASCS) instance. Which TWO AWS services can be used to implement a high-availability architecture for ASCS?
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
Options A and E are correct. Amazon EC2 Auto Recovery can automatically restart an ASCS instance if it fails due to underlying hardware issues, providing a basic level of high availability. Amazon Route 53 can be configured with DNS failover to route traffic to a standby ASCS instance in another Availability Zone, enabling multi-AZ resilience. Option B (CloudFront) is a content delivery network and not designed for SAP ASCS HA. Option C (DMS) is a database migration service, irrelevant for ASCS. Option D (ELB) is typically not used for ASCS because ASCS requires a single active node with a virtual IP or DNS name, not load-balanced traffic.
