Which two are true about the Data Catalog?
The 'OCI Data Catalog' has two true characteristics: 'Harvest object storage to derive schemas' (B), as it scans OCI Object Storage to extract metadata and schemas, and 'Discover data using powerful search' (C), offering robust search capabilities for data discovery. 'Management is required' (A) is vague and not a defining trait, and 'Data Catalog does not integrate with Autonomous Database' (D) is false, as it integrates seamlessly for metadata management. Oracle's documentation confirms these features.
