Identify two types of solutions in which you would need to use Active Data Guard and Golden Gate together.

A. a solution that provides zero-data-loss protection at any distance without impacting database performance

B. a solution for disaster protection and database rolling upgrades for a mission-critical OLTP database, where you also want to extract data from a data guard primary database for ETL update o' an enterprise data warehouse

C. a solution requiring minimal planned downtime and risk, using standby first patching, database rolling upgrades, and select platform migrations
