Which of the following statements about Oracle Autonomous Database is incorrect?

The statement regarding Oracle Autonomous Database that indicates it requires constant manual tuning is incorrect because one of the primary features of the Autonomous Database is its ability to automate many of the operational tasks that would traditionally require manual intervention. This includes performance tuning, where the database uses machine learning algorithms to optimize its performance without the need for continuous manual tuning by a database administrator.

In contrast, the other statements reflect true characteristics of Oracle Autonomous Database. It automates backups to ensure data protection without user input, provides scalability to handle varying workloads effectively, and incorporates automatic data security measures to protect sensitive data. The inherent design of the Autonomous Database allows it to operate efficiently and autonomously, minimizing the administration burden on users.
