Automatically adjusts capacity of SAP application servers
DNS failover and health checks
Distributes traffic across SAP instances
Infrastructure as code for multi-AZ deployment
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Elastic Load Balancing: Distributes incoming traffic across multiple EC2 instances in multiple Availability Zones.
In SAP on AWS, Elastic Load Balancing and Route 53 are key HA services. ELB distributes traffic across healthy instances, and Route 53 provides DNS failover. Auto Scaling helps maintain capacity but does not distribute traffic, and Lambda is not a primary HA component.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Elastic Load Balancing: Distributes incoming traffic across multiple EC2 instances in multiple Availability Zones.
Why this is correct
ELB distributes traffic across healthy instances in multiple AZs, supporting HA by routing requests away from failed instances.
Amazon Route 53: DNS-based failover routing to redirect traffic to a standby environment when primary fails.
Why this is correct
Route 53 health checks and failover routing enable automatic DNS failover to a standby environment for HA.
Amazon EC2 Auto Scaling: Distributes traffic to healthy EC2 instances.
Why it's wrong here
Incorrect — traffic distribution is the role of Elastic Load Balancing, not Auto Scaling.
AWS Lambda: Manages automatic failover of SAP applications across Availability Zones.
Why it's wrong here
Incorrect — Lambda is not typically used for SAP HA failover; that is managed by cluster software or other services.
