AWS Certified Advanced Networking – Specialty (ANS-C01) — Question 117
A company is running an online game on AWS. The game is played globally and is gaining popularity. Users are reporting problems with the game's responsiveness. Replay rates are dropping, and the company is losing subscribers. Game servers are located in the us-west-2 Region and use an Elastic Load Balancer to distribute client traffic.
The company has decided to deploy game servers to 11 additional AWS Regions to reduce the round-trip times of network traffic to game clients. A network engineer must design a DNS solution that uses Amazon Route 53 to ensure that user traffic is delivered to game servers with an optimal response time.
What should the network engineer do to meet these requirements?
Answer options
- 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.
Correct answer: B
Explanation
The correct choice is B because a latency routing policy in Amazon Route 53 directs user traffic to the region with the lowest latency, ensuring faster response times for players. Option A is incorrect as a weighted routing policy does not guarantee optimal performance based on latency. Option C, while useful for redundancy, does not prioritize latency, and Option D focuses on geographical location rather than response time, which may not yield the best performance.
