Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
One recovery point objective (RPO) of zero
Why it's wrong here
RPO is a recovery metric, not a backup storage location rule.
- ✗
One local copy
Why it's wrong here
Local copies are part of the '3' copies requirement.
- ✗
One full backup per day
Why it's wrong here
The frequency is independent of the 3-2-1 storage location rule.

One off-site copy
Why this is correct
The '1' represents an off-site, geographically isolated backup.
