Which statements are true about automated tuning? (Choose three)

Automated tuning refers to the features within the Oracle Autonomous Database that allow for performance enhancements without requiring significant manual intervention. The choice that highlights fast performance out of the box with zero tuning is accurate because one of the primary benefits of the Autonomous Database is its ability to automatically optimize itself for performance as workloads change. The system utilizes machine learning algorithms to adapt its performance settings, which is in line with the purpose of having an autonomous database.

The automatic adjustments made by Oracle's tuning mechanisms mean that users can often achieve optimal performance simply by using the database without needing to fine-tune their configurations manually. This results in a system that is not only efficient but also easier to manage, as it reduces the need for technical expertise in database tuning.

The other statements may not be correct or complete in capturing the essence of automated tuning. For instance, while web-based monitoring is a feature, it's not specifically a hallmark of automated tuning like the performance aspects are. Similarly, while resource management is a part of database operation, the focus of automated tuning is more on performance and optimization rather than just resource management plans. Lastly, monitoring parallel execution is typically done through automated means, contrasting with the notion that it needs to be monitored manually. Hence, the emphasis on zero tuning and
