Question #1088
Which AWS service enables the deployment of a fully managed, serverless NoSQL database with built-in scalability and high availability?
Amazon Aurora
Amazon DynamoDB
Amazon RDS
Amazon Redshift
Explanation
Amazon DynamoDB (B) is AWS's fully managed, serverless NoSQL database service. It automatically scales throughput and storage, handles replication across Availability Zones for high availability, and requires no server provisioning.
- Why other options are incorrect:
- A. Amazon Aurora: A managed relational database (SQL) compatible with MySQL/PostgreSQL, not NoSQL.
- C. Amazon RDS: A managed relational database service (supports MySQL, PostgreSQL, etc.), also not NoSQL.
- D. Amazon Redshift: A data warehousing service for analytics, not a NoSQL database.
Key Points: DynamoDB is serverless, NoSQL, and designed for seamless scalability and high availability. The other services are either SQL-based or serve different use cases.
Answer
The correct answer is: B
