Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Full database backup
Why this is correct
A full backup is the last line of defense if the migration fails.
- ✗
Adding more memory to the server
Why it's wrong here
Memory adds are independent of schema upgrades.
- ✓
Migration script validation in a staging environment
Why this is correct
Verifying the script in staging prevents unexpected production failures.

OS updates are separate from database schema migrations.
