Actual exam question for CompTIA's 220-1202 exam
Question #: 129
Topic #: 1
Which of the following methods would make data unrecoverable but allow the drive to be repurposed?

Suggested Answer: C Vote an answer

Comprehensive and Detailed Explanation From Exact Extract:
A low-level format (also referred to as a zero-fill or full format) writes over every sector on a storage device, effectively destroying the existing data and making recovery nearly impossible. Unlike degaussing, which renders the drive unusable, a low-level format maintains the integrity of the device, allowing it to be repurposed or reused.
A: Deleting partitions does not fully erase data; it only removes references in the partition table.
B: EFS (Encrypting File System) encrypts files but does not securely wipe them.
D: Degaussing destroys the magnetic structure of a drive, making it inoperable and not reusable.
