Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create at least three copies of your data, then store the copies on at least two different types of media, then ensure at least one copy is stored offsite, then regularly test your backups.
Why this is correct
This is the correct order because the 3-2-1 rule requires having three copies (step 1), on two different media (step 2), with one offsite (step 3), and testing ensures recoverability (step 4).
- ✗
Store the copies on at least two different types of media, then ensure at least one copy is stored offsite, then create at least three copies of your data, then regularly test your backups.
Why it's wrong here
This is incorrect because you must first have copies before you can decide on media types or offsite storage; creating copies after media selection is illogical.
- ✗
Create at least three copies of your data, then ensure at least one copy is stored offsite, then store the copies on at least two different types of media, then regularly test your backups.
Why it's wrong here
This is incorrect because the offsite copy should be stored on a specific media type; selecting media after offsite placement ignores the requirement to use different media for the copies.
- ✗
Regularly test your backups, then create at least three copies of your data, then store the copies on at least two different types of media, then ensure at least one copy is stored offsite.
Why it's wrong here
This is incorrect because testing can only occur after backups are created and stored; testing first provides no data to verify.
