Q85 — AWS DEA-C01 Ch.1

Question 85 of 100 | ← Chapter 1

A gaming company uses a NoSQL database to store customer information. The company is planning to migrate to AWS. The company needs a fully managed AWS solution that will handle high online transaction processing (OLTP) workload, provide single-digit Millisecond performance, and provide high availability around the world. Which solution will meet these requirements with the LEAST operational overhead?

• A. Amazon Keyspaces (for Apache Cassandra)
• B. Amazon DocumentDB (with MongoDB compatibility)
• C. Amazon DynamoDB ✓
• D. Amazon Timestream

Correct Answer: C. Amazon DynamoDB

Explanation

答案C正确。AmazonDynamoDB是一种完全托管的NoSQL数据库服务，专为处理高并发的在线事务处理(OLTP)工作负载而设计，能够提供低至个位数毫秒级的性能，并且具有全球范围内的高可用性。与其他选项相比，AmazonKeyspaces对于某些工作负载可能不太适用；AmazonDocumentDB主要针对与MongoDB兼容的场景；AmazonTimestream更侧重于时间序列数据的处理。综合考虑，AmazonDynamoDB能以最少的运营开销满足题中要求。
