A user has a non-relational key-value database. The user is looking for a fully managed AWS service that will offload the administrative burdens of operating and scaling distributed databases. The solution must be cost-effective and able to handle unpredictable application traffic.
What should a Database Specialist recommend for this user?
- A . Create an Amazon DynamoDB table with provisioned capacity mode
- B . Create an Amazon DocumentDB cluster
- C . Create an Amazon DynamoDB table with on-demand capacity mode
- D . Create an Amazon Aurora Serverless DB cluster
Suggested Answer: C
Explanation:
Reference: https://aws.amazon.com/dynamodb/
Key-value database -> DynamoDB Capable of dealing with unexpected application traffic -> on-demand capacity mode
A key-value database is a type of nonrelational database that uses a simple key-value method to store data. A key-value database stores data as a collection of key-value pairs in which a key serves as a unique identifier. On-demand mode is a good option to create new tables with unknown workloads. https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.ReadWriteCapacityMode.html#HowItWorks.OnDemand
