A : Correct — ElastiCache for Redis supports encryption at rest and in transit (PHI requirement), AND supports sorted sets for ranking/sorting cached data. Exactly meets both requirements.
redis is having the sorting functionality
* Amazon ElastiCache service provide in-memory cache in the cloud. * Redis and MemCache are the 2 popular options which ElastiCache offerd for us. * Both support encryption at rest and transist (previously only redis supported this). * Redis offerd advance features like datastructures, transactions ,pub/sub etc. Since question is asking about most cost effective solution(already buit with MYSQL) , we have to ignore the DynamoDB option . Now we can pick Redis due to its natual sort facility.
