SAP-C02 Design for New Solutions Practice Question
A company is designing a new application that will run on Amazon EC2 instances in an Auto Scaling group. The application must be able to distribute incoming traffic across multiple instances. Which TWO AWS services can be used for this purpose? (Choose TWO.)
⚠ Common exam trap
The SAP-C02 exam often tests the distinction between services that perform actual load balancing (ALB, NLB) versus services that provide DNS-based routing (Route 53) or content delivery (CloudFront) or global traffic optimization (Global Accelerator), leading candidates to mistakenly select Route 53 or CloudFront as load balancers.
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
✓
Network Load Balancer
Network Load Balancer (NLB) operates at Layer 4 (TCP/UDP) and can distribute incoming traffic across multiple EC2 instances in an Auto Scaling group with extremely low latency and high throughput. It is ideal for applications that require handling millions of requests per second while preserving the source IP address of clients.
