Oracle Cloud Infrastructure 2023 Architect Associate — Question 4

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

Answer options

• A. PDBs cannot be migrated to an Autonomous Database using plug, unplug, or clone.
• B. Unplug into a PDB archive, which can be uploaded to Object Storage.
• C. Unplug into an XML file so that the database and XML files can be uploaded to Object Storage.
• D. Create a database link from the source database to the Autonomous Database environment and clone the PDB.

Correct answer: B

Explanation

The correct answer is B because the customer needs to unplug their PDB into an archive format that can be uploaded to Object Storage, which is compatible with Autonomous Database. Option A is incorrect as it misstates the capabilities of PDB migration to Autonomous Database. Option C is wrong because unplugging into an XML file does not meet the requirements for migration. Option D suggests cloning via a database link, which is not a valid method for this scenario.
