Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 726 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 726
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company has deployed a multiplayer game for mobile devices. The game requires live location tracking of players based on latitude and longitude. The data store for the game must support rapid updates and retrieval of locations.

The game uses an Amazon RDS for PostgreSQL DB instance with read replicas to store the location data. During peak usage periods, the database is unable to maintain the performance that is needed for reading and writing updates. The game's user base is increasing rapidly.

What should a solutions architect do to improve the performance of the data tier?

  • A. Take a snapshot of the existing DB instance. Restore the snapshot with Multi-AZ enabled.
  • B. Migrate from Amazon RDS to Amazon OpenSearch Service with OpenSearch Dashboards.
  • C. Deploy Amazon DynamoDB Accelerator (DAX) in front of the existing DB instance. Modify the game to use DAX.
  • D. Deploy an Amazon ElastiCache for Redis cluster in front of the existing DB instance. Modify the game to use Redis.

Why are people voting for C? PostgreSQL is a relational DB. DynamoDB is NoSQL. It makes no sense

Specific to Redis, ElastiCache lets you “scale in” or “scale out” both reads and writes. Cluster mode offers added shard support, enabling write scaling. https://aws.amazon.com/blogs/database/building-a-real-time-gaming-leaderboard-with-amazon-elasticache-for-redis/

The answer C is not making any sense with "Deploy Amazon DynamoDB Accelerator (DAX) in front of the existing DB instance.", because AWS DynamoDB is a DBaaS.

Vote for C (DAX) as ElastiCache for Redis cluster only helps on read operation but not white.

Yeah, but this is an online game that need to update everything instantly so i don't think that caching is the right method here think about it, you are making movments in the online game its like loading new data all the time, so each time you move you load the cache for next time usage. what if you dont need to use it again? i dont think elasticache is the right method here so it leave us with DAX what do you think?

i agree with DAX, but how it can be deploying in front of DB instance? Since that is a DBaaS.
