During the decommissioning phase of a hardware project, a security administrator is tasked with ensuring no sensitive data is released inadvertently. All paper records are scheduled to be shredded in a crosscut shredded, and the waste will be burned. The system drives and removable media have been removed prior to e-cycling the hardware.
Which of the following would ensure no data is recovered from the system droves once they are disposed of?
A. Overwriting all HDD blocks with an alternating series of data.
B. Physically disabling the HDDs by removing the dive head.
C. Demagnetizing the hard drive using a degausser.
D. Deleting the UEFI boot loaders from each HDD.

I found this online.
Unfortuna degaussertely, degaussing does not work. It sounds so simple. You take a giant electromagnet, put your hard disk inside and you are done. And we call it a degausser. The hard disk manufacturers, however, have ensured that magnetic disks are protected by something called a Faraday cage. This enclosure protects the place where the disks storing information is located from all kinds of radiation. The manufacturer of the degausser promises that HIS degausser is actually strong enough and reliable. But you can never really be sure. Back-up tapes, VHS tapes, and bank cards seem to be more appropriate media to erase using a degausser, but even then there are no guarantees. A number of experiments in our data security centre in Uden have confirmed this. It is true that a hard disk will fail immediately if even held near a degausser. However, this is because the electronics, which are outside the Faraday cage, are damaged by the magnetic field. If you simply replace the circuit board, the hard disk works as if it were new, and all the data will still be in place! Conclusion: degausser does not work

So based on the above, shouldn’t it be based on A if we are going to apply real life scenario here?
Anybody else tracking A here?
Depending on the sensitivity of the information, wiping a drive may be sufficient.
Both A & C are good answers depending how you interpret the question.
Since they mentioned that “No data is recovered from the system drives once they are disposed of” “A” would be the best choice.
They also mention e-cycling, this would mean the drives will no longer be in service, making C a good choice.
CompTIA takes the medal for the most jacked up questions.
I see why you are looking at A, but consider this, the questions asks:
Which of the following would ensure no data is recovered from the system droves once they are disposed of?
Overwriting the drives implies they can be used again for another purpose, the question talks about disposal or e-cycling and here the best practice is C, demagnetize and e-cycle…. this both destroys the data and it is ready for disposal.
You finally got one right
hahahahah
