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.

Selected Answer: B

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
