Question

A company manages an application that uses Amazon ElastiCache for Redis with two extra-large nodes spread across two different Availability Zones. The company’s IT team discovers that the ElastiCache for Redis cluster has 75% freeable memory. The application must maintain high availability. What is the MOST cost-effective way to resize the cluster?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Perform an online resizing for the ElastiCache for Redis cluster. Change the node types from extra-large nodes to large nodes. Amazon ElastiCache provides in-memory caching (Redis/Memcached) to reduce latency and offload the database. This option delivers the requirement at the lowest cost.
