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 server that uses a hardware RAID controller. The company policy requires that all data be destroyed, but the drives must be returned to the leasing company. Which method ensures data is unrecoverable while preserving the drives?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the RAID controller's built-in 'secure erase' or 'low-level format' command.
Hardware RAID controllers often use non-standard sector layouts, making software-based wiping unreliable. The best approach is to use the RAID controller's own low-level format or secure erase utility, which understands the controller's geometry.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Remove the drives and use a degausser on each one.
Why it's wrong here
Degaussing may damage the drives and could void the lease agreement. It also may not be effective on all drive types.
✗
Perform a secure erase using a bootable utility like DBAN.
Why it's wrong here
DBAN may not correctly address RAID controller translation, leaving data in hidden areas. It is not reliable for hardware RAID.
✓
Use the RAID controller's built-in 'secure erase' or 'low-level format' command.
Why this is correct
The controller's utility can access all sectors, ensuring complete data removal while keeping drives functional for return.

✗
Physically drill through the drive enclosures.
Why it's wrong here
Drilling damages the drives, violating the lease requirement to return functional drives.

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.
