You develop a solution for an entertainment company. The company has built an app that uses an Azure SQL database.
You need to implement caching to improve the performance of all database queries by caching frequently accessed data while minimizing cost. The cache must be highly available and replicated for failover.
What should you create?

A. Azure Redis Cache Database using a Premium Tier configuration. Use Redis Clusters to shard data across multiple nodes.
B. Azure Redis Cache Database using a Basic Tier configuration.
C. Azure Redis Cache Database using a Standard Tier configuration.

B: Basic tier does not support cache replication.
D: Redis clusters are used to shard data, not to backup data.
