Correct answer & explanation
✓
AWS Elastic Load Balancing (NLB)
AWS Route 53 provides DNS-based failover routing to redirect traffic to the DR region. AWS Elastic Load Balancing (NLB) is used to distribute traffic to the HANA instances and can be used with a floating IP. AWS Direct Connect is not required. AWS CloudFormation is not needed for automatic failover. AWS Shield is for DDoS protection.

AWS Elastic Load Balancing (NLB)
Why this is correct
NLB can be used with a static IP and health checks to route traffic to the active HANA instance.

Why it's wrong here
Direct Connect is a dedicated network connection, not used for automatic failover.
- ✗
AWS CloudFormation
Why it's wrong here
CloudFormation is for infrastructure as code, not for failover automation.
