Which statements are true about ADB? (Choose two)

The statement about ADB that highlights its ability to reduce data management costs is accurate because ADB, or Autonomous Database, is designed with built-in automation features that optimize resource usage and streamline data management processes. By leveraging advanced technologies such as machine learning, it minimizes the need for manual interventions and reduces the overhead associated with data handling, leading to a significant decrease in costs associated with data management tasks.

Additionally, the choice that mentions the complete automation of operations and tuning correctly reflects another significant benefit of ADB. This automation facilitates efficient administration by managing routine tasks without human intervention, thereby lowering operational costs. The self-driving capabilities ensure database performance is continually optimized, which can result in substantial savings related to both personnel and maintenance efforts.

The incorrect options indicate limitations or drawbacks of other systems or scenarios, contrasting with the advantages presented by ADB. Such systems may have longer provisioning times or be limited in scalability options, further underscoring the benefits promoted by the correct statements.
