Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Three copies on two different media types, with one copy stored offsite
Why this is correct
This follows the 3-2-1 backup rule.
- ✗
Three copies on three different external hard drives stored in the same building
Why it's wrong here
All copies are on the same type of medium and no offsite copy.
- ✗
Two copies on the same server, one on a different server
Why it's wrong here
Two copies on the same server use the same medium and do not meet the 'two different media' requirement.
- ✗
One copy on the same drive, one on an external drive, one in the cloud
Why it's wrong here
The first copy on the same drive is not a separate copy; all should be distinct.
