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.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OCI Object Storage lifecycle policies exclusively
Why it's wrong here
Incorrect. Object storage is used for staging dumps, but the core migration engine relies on RMAN/Data Guard.
- ✓
Oracle RMAN and Oracle Data Guard
Why this is correct
Correct. For physical migrations, ZDM automates RMAN backup/restore and Data Guard setup for near-zero downtime transitions.
- ✗
Third-party ETL pipelines and CSV flat file generation
Why it's wrong here
Incorrect. ZDM automates native database engines, not third-party ETL tools.
- ✗
MySQL Enterprise Backup and InnoDB replication
Why it's wrong here
Incorrect. MySQL tools are irrelevant to migrating Oracle Databases.
