Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run the DBMS_CLOUD.PREPARE_FOR_AUTONOMOUS PL/SQL package on the source database
When migrating to Autonomous Database using Data Pump, you must run the DBMS_CLOUD.PREPARE_FOR_AUTONOMOUS procedure or use the Autonomous Database Migration tool to check and convert incompatible tablespaces, segments, and objects.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable Automatic Workload Repository (AWR) collection on the source database
Why it's wrong here
Incorrect. AWR collection is irrelevant to Data Pump migration compatibility.
- ✗
Convert the source database into an Oracle Multitenant Container Database with a single pluggable database
Why it's wrong here
Incorrect. While Autonomous Database uses PDB architecture under the hood, the migration source does not strictly need to be converted to a local multitenant container beforehand if Data Pump is used.
- ✓
Run the DBMS_CLOUD.PREPARE_FOR_AUTONOMOUS PL/SQL package on the source database
Why this is correct
Correct. This package performs necessary pre-checks and transformations to ensure compatibility with Autonomous Database.
- ✗
Manually drop all custom triggers and indexes to prevent import failures
Why it's wrong here
Incorrect. Custom indexes and triggers are supported and should not be dropped manually.
