C. True, ElastiCache supports the Redis key-value store.
D. False, ElastiCache supports the Redis key-value store only if you are in a VPC environment.

Correct Answer: C

Explanation:

Explanation: This is true. ElastiCache supports two open-source in-memory caching engines:
1. Memcached – a widely adopted memory object caching system.
ElastiCache is protocol compliant with Memcached, so popular tools that you use today with existing Memcached environments will work seamlessly with the service.
2. Redis – a popular open-source in-memory key-value store that supports data structures such as sorted sets and lists.
ElastiCache supports Master / Slave replication and Multi-AZ which can be used to achieve cross AZ redundancy. Reference: https://aws.amazon.com/elasticache/
