ISC2 CC Practice Question: Business Continuity, Disaster Recovery, and Incident Response
A company follows the 3-2-1 backup rule. It has two full backups: one on an external hard drive in the server room and one on tape in a safe on-site. Which step should be taken to fully comply with the rule?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Store the tape copy in a secure offsite location
The 3-2-1 rule requires three copies of data (including the original), stored on at least two different media types, with at least one copy stored offsite. Currently, the company has the original data plus two backups (external HDD and tape) — three copies total — but both backups are on-site. To fully comply, one of the backup copies must be moved to an offsite location. Option B, storing the tape copy offsite, satisfies the '1 offsite' requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
No action needed; the rule is satisfied
Why it's wrong here
The rule requires an offsite copy, which is missing.
- ✓
Store the tape copy in a secure offsite location
Why this is correct
This ensures one copy is offsite.
- ✗
Use cloud storage as an additional copy
Why it's wrong here
While cloud can be offsite, the rule requires at least one offsite; moving the tape offsite also works.
- ✗
Add a third copy to the external hard drive
Why it's wrong here
This does not satisfy the offsite requirement.
