Selected Answer: A
Amazon DynamoDB Accelerator (DAX) is a fully managed, highly available, in-memory cache for Amazon DynamoDB that delivers up to a 10 times performance improvement—from milliseconds to microseconds—even at millions of requests per second. https://aws.amazon.com/dynamodb/dax/#:~:text=Amazon%20DynamoDB%20Accelerator%20(DAX)%20is,millions%20of%20requests%20per%20second.

Amazon ElastiCache for Redis would help with "caching requests", but not " improve database response" itself.

Selected Answer: A
DAX is least operations overhead. B: Redshift, although powerful, but is for analytics C: Downgrading to RDS won't help D: EC for Redis is more for persistent caching so would be good but lot of operational overhead
