Topic 1 Question 169
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?
Amazon CloudFront
Amazon ElastiCache for Memcached
Amazon ElastiCache for Redis in cluster mode
Amazon DynamoDB Accelerator (DAX)

- 正解だと思う選択肢: C
Should be C since ElastiCache for Redis supports encryption at rest and in transit. ElastiCache for Memcached does not support encryption at rest. DynamoDB Accelerator is for DynamoDB and does not fit this case.
