Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Modify the DB instance → Set backup retention period to a value greater than 0 → Apply the changes immediately → Confirm the modification
Why this is correct
This is correct because to enable automated backups, you must first modify the instance settings, set the backup retention period to a non-zero value, then apply the change immediately to take effect, and finally confirm the modification.
- ✗
Set backup retention period to a value greater than 0 → Modify the DB instance → Apply the changes immediately → Confirm the modification
Why it's wrong here
This is incorrect because you cannot set the backup retention period before entering the modification screen; the setting is part of the modify process.
- ✗
Modify the DB instance → Apply the changes immediately → Set backup retention period to a value greater than 0 → Confirm the modification
Why it's wrong here
This is incorrect because you must set the backup retention period before applying changes; applying first would not enable backups.
- ✗
Confirm the modification → Modify the DB instance → Set backup retention period to a value greater than 0 → Apply the changes immediately
Why it's wrong here
This is incorrect because confirmation should be the last step after all settings are applied.
