Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 103 discussion

Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 103
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

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?

  • 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.

Route 53 multivalue answer option allows for checking for health status of backend resources, it can't test latencies.

Just a hint for exam readiness. If you are exam ready you should answer this question with way under 60 seconds. You should spot quickly that Global Accelerator is not an option and that this is just about Route53 policies. Then you should look out for the latency option. In case this was not available (well it is here) geolocation/proximity would be (not ideal but better than nothing) alternatives.

Selected Answer: C
Option C provides more flexibility by considering the actual response time from the game client's perspective. It allows the client to choose the server with the best response time based on latency tests. This approach can be more effective in situations where network latency alone may not accurately reflect the actual responsiveness of the game servers.
