SOA-C02 Networking and Content Delivery Practice Question
A SysOps administrator is designing a highly available web application across multiple AWS regions. The application uses an Application Load Balancer in each region. Which TWO services can be used to route traffic to the closest regional load balancer based on latency?

Correct answer & explanation
✓
AWS Global Accelerator
For routing traffic to the closest regional load balancer based on latency, two appropriate services are AWS Global Accelerator (option A) and Amazon Route 53 latency-based routing (option D). AWS Global Accelerator uses anycast IPs to direct users to the nearest edge location, then routes traffic over the AWS global network to the closest regional load balancer, providing latency-based routing. Amazon Route 53 latency-based routing directs traffic to the AWS region with the lowest latency for the user. Geoproximity routing (option B) routes based on geographic location, not primarily latency. Weighted routing (option C) distributes traffic by weight, and CloudFront with origin groups (option E) is for failover and content delivery, not latency-based routing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
AWS Global Accelerator
Why this is correct
Global Accelerator uses Anycast IPs, not latency routing.
- ✗
Amazon Route 53 geoproximity routing
Why it's wrong here
Geoproximity routing routes based on user location.
- ✗
Amazon Route 53 weighted routing
Why it's wrong here
Weighted routing distributes traffic by weight, not latency.
- ✓
Amazon Route 53 latency-based routing
Why this is correct
Latency routing routes to the region with lowest latency.
- ✗
Amazon CloudFront with origin groups
Why it's wrong here
Origin groups are for failover, not latency routing.
