Answer: Establish an Amazon ElastiCache for Redis cluster with a caching strategy in the application code.
The correct answer is D: Establish an Amazon ElastiCache for Redis cluster with a caching strategy in the application code. This solution is optimal because Amazon ElastiCache for Redis can act as a high-performance, in-memory data store and cache, enabling fast access to frequently read data. Implementing a caching strategy, such as write-through caching, ensures that data is written to both the cache and the primary RDS database simultaneously, keeping the cache updated. This reduces latency and load on the RDS database, making it suitable for applications with high read demand and rapidly changing data.
