The company is moving the database to AWS and needs to minimize the time that is required for those administration activitiesWhich AWS service should the company use to meet this requirement?
Amazon ElastiCache
Amazon EC2
Amazon RDS
Amazon DynamoDB
Explanations:
Amazon ElastiCache is a caching service designed to improve application performance by providing in-memory caching capabilities. It does not directly manage databases or reduce database administration tasks.
Amazon EC2 provides scalable computing capacity in the cloud but requires users to manage the underlying infrastructure, including database administration tasks. It does not minimize database administration time.
Amazon RDS (Relational Database Service) is a managed database service that automates database administration tasks such as backups, patching, monitoring, and scaling. This reduces the time spent on administration activities significantly.
Amazon DynamoDB is a fully managed NoSQL database service. While it minimizes operational overhead, it is not a direct replacement for an Oracle relational database and does not provide the same capabilities as Amazon RDS for Oracle databases.
