Objective 2.9
220-1202Compare and contrast common data destruction and disposal methods.
Objective 2.9 sits in Security, which carries 28% of the A+ Core 2 exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A technician sanitizes a retired drive with the standard write commands the device already exposes, guarding only against simple noninvasive recovery. Which category of sanitization is that?
Correct.
Checked against learn.microsoft.com, August 2026Concept
Sanitization is graded by the recovery effort it defeats, not by the tool used. The weakest grade defeats ordinary software recovery, the middle grade defeats laboratory recovery, and the strongest also ends the media's usefulness.
Why C
Logical techniques driven through the device's own read and write interface, such as rewriting every user-addressable location or resetting to factory state, sit at the first grade and stop only simple noninvasive recovery.

Now you: objective 2.9 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
Failed solid-state drives in a datacenter cannot complete a clear operation, so they must be purged on site before disposal. Which treatment suits chip-based media?
Sample question 2 of 3
An audit requires you to show that each retired drive was accounted for from the moment it left the rack until it was destroyed, with no unexplained gap. Which control provides that record?
Sample question 3 of 3
Confidential files were deleted from an NTFS volume that stays in production. Which cipher parameter overwrites the free space those files used to hold?
