PAS-C01 Application Load Balancer Practice Question
A company runs SAP S/4HANA on AWS with a three-tier architecture. The operations team receives alerts that the application server's CPU utilization is consistently above 90%. The team wants to add an additional application server to distribute the load. Which AWS service should be used to register the new instance with the SAP system's load balancer?
⚠ Common exam trap
Candidates may confuse NLB with ALB. For SAP applications using HTTP/HTTPS, ALB is appropriate.

Correct answer & explanation
✓
Application Load Balancer (ALB)
(Application Load Balancer). ALB can register EC2 instances as targets and distribute incoming traffic across multiple instances, making it suitable for adding an additional application server to distribute the load. Option A (CloudFront) is a CDN service, not a load balancer. Option B (Network Load Balancer) operates at the transport layer (TCP/UDP) and is not ideal for application-level load balancing. Option C (Route 53) is a DNS service and does not register instances directly.
