Oracle Cloud Infrastructure 2020 Architect Associate — Question 52

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)? (Choose the best answer.)

Answer options

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

Correct answer: C

Explanation

The correct answer is C because pluggable databases cannot be directly migrated to Autonomous Database using unplug or clone methods. Options A, B, and D suggest processes that are not supported for migrating a pluggable database to ADB.
