Oracle Cloud Infrastructure 2023 AI Foundations Associate — Question 34

Which two statements are true about online pluggable database (PDB) relocation? (Choose two.)

Answer options

• A. PDB relocation with no version change can be performed with near-zero downtime.
• B. PDB with the ASCII character set can be relocated to a container database (CDB) with the AL32UTF8 character set.
• C. Online PDB relocation can achieve a zero downtime upgrade.
• D. Database version downgrade can be achieved with PDB relocation.

Correct answer: A, B

Explanation

Option A is correct because PDB relocation without a version change can indeed be performed with near-zero downtime. Option B is also correct as it is permissible to relocate a PDB with the ASCII character set to a CDB configured with the AL32UTF8 character set. Options C and D are incorrect because online PDB relocation does not inherently provide zero downtime upgrades or allow for version downgrades.
