AWS Certified Solutions Architect – Professional — Question 876

Which of the following cache engines does Amazon ElastiCache support?

Answer options

• A. Amazon ElastiCache supports Memcached and Redis.
• B. Amazon ElastiCache supports Redis and WinCache.
• C. Amazon ElastiCache supports Memcached and Hazelcast.
• D. Amazon ElastiCache supports Memcached only.

Correct answer: A

Explanation

Amazon ElastiCache is a fully managed in-memory data store service that natively supports two popular open-source engines: Redis and Memcached. Other caching engines like WinCache and Hazelcast are not supported by the service. Therefore, any option limiting support to just Memcached or including unsupported engines is incorrect.
