Question

A company is using Amazon RDS as the backend database for its application. After a recent marketing campaign, a surge of read requests to the database increased the latency of data retrieval from the database. The company has decided to implement a caching layer in front of the database. The cached content must be encrypted and must be highly available. Which solution will meet these requirements?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Amazon ElastiCache for Redis in cluster mode Amazon ElastiCache provides in-memory caching (Redis/Memcached) to reduce latency and offload the database. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
