B Though DynamoDB offers consistent single-digit-millisecond latency, DynamoDB + DAX takes performance to the next level with response times in microseconds for millions of requests per second for read-heavy workloads. With DAX, your applications remain fast and responsive, even when a popular event or news story drives unprecedented request volumes your way. No tuning required.

Similar question with different wordings was on my test that I passed on Nov 20 2021. I picked B. Roughly half of the questions are from this 500 examtopics dump. But other half were unheard of new and lengthy ones in my test. Some of those questions had similarities but had twisted options. Good luck ya'll.

B Because The organization lacks the people necessary to manage extra operational expenses... - You do not need to modify application logic because DAX is compatible with existing DynamoDB API calls https://aws.amazon.com/dynamodb/dax/

I will like to agree with Option D. Amazon ElastiCache for Memcached is a great choice for implementing an in-memory cache to decrease access latency, increase throughput, and ease the load off your relational or NoSQL database. Amazon ElastiCache can serve frequently requested items at sub-millisecond response times, and enables you to easily scale for higher loads without growing the costlier backend database layer. Database query results caching, persistent session caching, and full-page caching are all popular examples of caching with ElastiCache for Memcached. https://aws.amazon.com/elasticache/memcached/

Unfortunately ElastiCache would need App code modification to access the cache svc.
