Oracle Cloud Infrastructure 2019 Architect Associate — Question 17

Your customer has upgraded their on premise 11.2 database to 12.2. During this migration the database was migrated to a pluggable database and is now in production.
How should the customer unplug their database to migrate to Autonomous Database (ADB)?

Answer options

• A. Pluggable databases cannot be migrated to ADB using plug, unplug or clone.
• B. Create a database link from source database to the ADB environment and clone the PDB.
• C. Unplug to an xml file so database files and xml file can be uploaded to object storage.
• D. Unplug into a pdb archive which can be uploaded to object storage.

Correct answer: B

Explanation

The correct answer is B because creating a database link and cloning the PDB is the supported method for migrating to ADB. Option A is incorrect as it misstates the capabilities of pluggable databases. Options C and D suggest methods that do not align with the migration process to ADB.
