Topic 1 Question 22
A developer is creating an application that will store personal health information (PHI). The PHI needs to be encrypted at all times. An encrypted Amazon RDS for MySQL DB instance is storing the data. The developer wants to increase the performance of the application by caching frequently accessed data while adding the ability to sort or rank the cached datasets. Which solution will meet these requirements?
Create an Amazon ElastiCache for Redis instance. Enable encryption of data in transit and at rest. Store frequently accessed data in the cache.
Create an Amazon ElastiCache for Memcached instance. Enable encryption of data in transit and at rest. Store frequently accessed data in the cache.
Create an Amazon RDS for MySQL read replica. Connect to the read replica by using SSL. Configure the read replica to store frequently accessed data.
Create an Amazon DynamoDB table and a DynamoDB Accelerator (DAX) cluster for the table. Store frequently accessed data in the DynamoDB table.

A You can use Amazon Elasticache for Redis Sorted Sets to easily implement a dashboard that keeps a list of sorted data by their rank. https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/elasticache-use-cases.html#elasticache-for-redis-use-cases-gaming https://aws.amazon.com/elasticache/redis-vs-memcached/

ElastiCache for Redis also features Online Cluster Resizing, supports encryption, and is HIPAA eligible and PCI DSS compliant.

To meet the requirements of caching frequently accessed data while adding the ability to sort or rank cached datasets, a developer should choose Amazon ElastiCache for Redis. ElastiCache is a web service that provides an in-memory data store in the cloud, and it supports both Memcached and Redis engines. While both engines are suitable for caching frequently accessed data, Redis is a better choice for this use case because it provides sorted sets and other data structures that allow for sorting and ranking of cached datasets. The data in ElastiCache can be encrypted at rest and in transit, ensuring the security of the PHI. Therefore, option A is the correct answer.
