Question 75 of 100 | ← Chapter 11

Q775. A company is deploying an application in three AWS Regions using an Application Load Balancer. Amazon Route 53 will be used to distribute traffic between these Regions.Which Route 53 configuration should a solutions architect use to provide the MOST high-performing experience?

• A. Create an A record with a latency policy. ✓
• B. Create an A record with a geolocation policy.
• C. Create a CNAME record with a failover policy.
• D. Create a CNAME record with a geoproximity policy.

Correct Answer: A. Create an A record with a latency policy.

Explanation

A OR B.By creating an A record with a latency policy, Route 53 can route traffic based on the lowest network latency to the available AWS Region. This ensures that users are directed to the Region that offers the best performance for their location.Here's why the other options are not the most suitable choices:B. Create an A record with a geolocation policy:A geolocation policy routes traffic based on the geographic location of the user making the request. While geolocation routing can be useful in certain scenarios, it does not necessarily guarantee the most high-performing experience, as it does not consider network latency.C. Create a CNAME record with a failover policy:A failover policy is used when there is a primary and secondary resource, and Route 53 automatically routes traffic to the secondary resource in case of a failure. However, it does not address the requirement of distributing traffic between three AWS Regions for high performance.D. Create a CNAME record with a geoproximity policy:Geoproximity routing policies allow you to route traffic based on the geographic location of the resource being accessed. While geoproximity routing can be beneficial in certain scenarios, it does not directly address the requirement of distributing traffic between three AWS Regions for the most high-performing experience.Therefore, the recommended Route 53 configuration to provide the most high-performing experience when distributing traffic between three AWS Regions using an Application Load Balancer is:A. Create an A record with a latency policy.
