AWS Certified SysOps Administrator – Associate (legacy) — Question 53

You have been asked to propose a multi-region deployment of a web-facing application where a controlled portion of your traffic is being processed by an alternate region.
Which configuration would achieve that goal?

Answer options

• A. Route53 record sets with weighted routing policy
• B. Route53 record sets with latency based routing policy
• C. Auto Scaling with scheduled scaling actions set
• D. Elastic Load Balancing with health checks enabled

Correct answer: A

Explanation

The correct answer is A because Route53's weighted routing policy allows you to direct a specified percentage of traffic to different resources, enabling controlled traffic distribution across regions. Option B, latency-based routing, focuses on directing traffic to the region with the lowest latency rather than controlled distribution. Options C and D do not address multi-region traffic management directly.
