Option C is better as we need replication and snapshots

A - If the root cause is database-related (for example, read-heavy traffic), then OK. However, "Performance metrics indicate that simply scaling the database will not help." means that maybe caching is a more effective option. B - Migrating from a relational database to DynamoDB requires so much effort. Such a headache. C - ElastiCache for Redis supports replication and snapshots, and of course, sub-millisecond response times. D - Memcached lacks built-in persistence, which is why game applications rarely use it.

capabilities for snapshots, replication

Why I choose B? # 1 High-performance, low latency: DynamoDB is a NoSQL database designed for fast, sub-millisecond response times, which is crucial for handling the high volume of metadata requests from a popular mobile game. # 2 Scalability: DynamoDB scales automatically to handle fluctuating traffic without the need to manually manage database instances, making it ideal for a rapidly growing game. # 3 Global tables: This feature allows for geographically distributed data access, ensuring quick response times for players across different regions.

C is correct

Thinking the capabilities with "snapshots, replication, and sub-millisecond response times" is for the Database or selected solution(ElastiCache).

C is correct
