Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 483
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company is migrating infrastructure for its massive multiplayer game to AWS. The game’s application features a leaderboard where players can see rankings in real time. The leaderboard requires microsecond reads and single-digit-millisecond write latencies. The datasets are single-digit terabytes in size and must be available to accept writes in less than a minute if a primary node failure occurs.

The company needs a solution in which data can persist for further analytical processing through a data pipeline.

Which solution will meet these requirements with the LEAST operational overhead?

  • B. Create an Amazon ROS database with a read replica. Configure the application to point writes to the writer endpoint. Configure the application to point reads to the reader endpoint.
  • C. Create an Amazon MemoryDB for Redis cluster in Muit-AZ mode Configure the application to interact with the primary node.
  • D. Create multiple Redis nodes on Amazon EC2 instances that are spread across multiple Availability Zones. Configure backups to Amazon S3.

C is right. Amazon MemoryDB for Redis is a fully managed, Redis-compatible, in-memory database service that delivers ultra-fast performance with microsecond read and single-digit millisecond write latencies. It supports Multi-AZ replication for high availability and durability. If the primary node fails, MemoryDB automatically fails over to a replica node in less than a minute.

To meet the requirements of low latency and high availability for a gaming leaderboard, Amazon MemoryDB for Redis is the best solution. It provides microsecond read latencies and single-digit millisecond write latencies, ensuring fast data access and updates, which is critical for real-time applications like leaderboards. This setup minimizes operational overhead compared to managing multiple EC2 instances or configuring a traditional RDS database
