AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A SaaS company operates two identical stacks of microservices behind regional Application Load Balancers (ALBs) in us-east-1 and eu-west-1. Customers need to reach the service through a pair of static, globally anycast IP addresses that automatically route each client to the closest healthy region. Operations must continue to see the original client IP in the ALB access logs. Which configuration meets these requirements while using the fewest AWS resources?

  • Create a single AWS Global Accelerator with one TCP listener on port 443 and two endpoint groups (us-east-1 and eu-west-1) that reference the regional ALB endpoints; use the default health checks and no client affinity.

  • Deploy an Amazon CloudFront distribution that lists both ALBs as origins, enable Origin Failover, and rely on CloudFront edge locations for latency-based routing.

  • Provision two separate Global Accelerators-one per region-map each to its regional ALB, and use Route 53 weighted DNS records to balance traffic across the accelerators.

  • Configure Route 53 latency-based A records that point to the ALB DNS names, attach health checks to each record, and use a traffic policy to expose static IP addresses.
