Your application uses an Amazon DynamoDB table to serve user profile information. You notice an increase in the read load causing throttling issues due to repeated accesses to the same items. Which caching strategy should you implement to minimize read latency and reduce the load on the DynamoDB table while ensuring data consistency for frequently accessed items?
Use a write-through cache to preload user profiles into Amazon ElastiCache
Set a time-to-live (TTL) for user profiles to invalidate the cache periodically
Apply lazy loading to load user profiles into the cache only when updates occur
Store user profiles in Amazon S3 and synchronize them with DynamoDB
Implement a read-through cache using Amazon ElastiCache
Increase the read capacity units (RCUs) for the DynamoDB table to handle the higher load
