- A
Remove each drive and use a hammer to break the platters.
Why wrong: Removing drives violates the policy of not disassembling the array, and hammering may leave data recoverable on some platters.
- B
Use a degausser that can accommodate the entire array chassis.
A degausser can destroy data on all magnetic drives simultaneously without removal, though it may damage the controller—acceptable for decommissioning.
- C
Perform a secure erase on each drive via the RAID controller.
Why wrong: Secure erase commands may not be supported by all RAID controllers, and the process is time-consuming; also, it may not meet policy if drives are not individually removed.
- D
Reformat the array and reuse it for non-sensitive data.
Why wrong: Reformatting does not destroy data; it only resets the file system, leaving data recoverable.
220-1202 Data Destruction and Disposal Practice Question
This 220-1202 practice question tests your understanding of data destruction and disposal. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is decommissioning a RAID array of 10 hard drives that contained sensitive HR data. The company policy requires that data be destroyed without removing individual drives from the array. Which method is most appropriate?
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
Use a degausser that can accommodate the entire array chassis.
The correct answer is to use a degausser designed for large media, which can destroy data on all drives simultaneously without disassembly. However, this may damage the RAID controller. Alternatively, a bulk eraser could be used. This question tests understanding of bulk destruction methods for RAID arrays.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
Quick reference
RAID Level Comparison
| RAID Level | Min Disks | Fault Tolerance | Read | Write | Usable Capacity |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Good | Moderate | 50% |
| RAID 5 | 3 | 1 disk | Good | Moderate | 67–94% |
| RAID 6 | 4 | 2 disks | Good | Lower | 50–88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
RAID is not a backup strategy — it protects against disk failure but not against accidental deletion, ransomware, or site-level events.
