AWS Certified Solutions Architect - Associate

  • Topic 1 Question 431

    A company has developed a new video game as a web application. The application is in a three-tier architecture in a VPC with Amazon RDS for MySQL in the database layer. Several players will compete concurrently online. The game’s developers want to display a top-10 scoreboard in near-real time and offer the ability to stop and restore the game while preserving the current scores.

    What should a solutions architect do to meet these requirements?

    • Set up an Amazon ElastiCache for Memcached cluster to cache the scores for the web application to display.

    • Set up an Amazon ElastiCache for Redis cluster to compute and cache the scores for the web application to display.

    • Place an Amazon CloudFront distribution in front of the web application to cache the scoreboard in a section of the application.

    • Create a read replica on Amazon RDS for MySQL to run queries to compute the scoreboard and serve the read traffic to the web application.
