Answer: Create Route 53 records for the Elastic Load Balancers in each Region. Specify a latency routing policy. Set the Region to the Region where the Elastic Load Balancer is deployed.
To ensure that user traffic is delivered to game servers with an optimal response time across multiple AWS Regions, the network engineer should use Amazon Route 53's latency-based routing policy. This policy directs traffic to the AWS Region that provides the lowest latency for the user, which is crucial for the responsiveness of an online game. Option B correctly suggests creating Route 53 records for the Elastic Load Balancers in each Region and specifying a latency routing policy. This approach automatically routes traffic to the Region that offers the best latency, improving the game's responsiveness and user experience. Options A, C, and D do not directly address the requirement for optimal response time based on latency. Weighted routing (A) distributes traffic based on assigned weights, not latency. Multivalue answer routing (C) returns multiple values for a DNS query but does not ensure the lowest latency. Geolocation routing (D) routes traffic based on the geographic location of the users, not necessarily the lowest latency.

A company is hosting a globally popular online game on AWS, with game servers located in the us-west-2 Region and an Elastic Load Balancer distributing client traffic. Users are experiencing responsiveness issues, leading to declining replay rates and subscriber loss. To address this, the company plans to deploy game servers across 11 additional AWS Regions to minimize network round-trip times for game clients.
What DNS solution using Amazon Route 53 should a network engineer implement to ensure user traffic is routed to game servers with the best possible response time?
A
Create Route 53 records for the Elastic Load Balancers in each Region. Specify a weighted routing policy. Calculate the weight by using the number of clients in each Region.
B
Create Route 53 records for the Elastic Load Balancers in each Region. Specify a latency routing policy. Set the Region to the Region where the Elastic Load Balancer is deployed.
C
Create Route 53 records for the Elastic Load Balancers in each Region. Specify a multivalue answer routing policy. Test latency from the game client, and connect to the server with the best response.
D
Create Route 53 records for the Elastic Load Balancers in each Region. Specify a geolocation routing policy. Set the location to the Region where the Elastic Load Balancer is deployed.
