Exam CAS-004 topic 1 question 128 discussion

If you totally destroy the drive or whatever, there is no chance of recovery. I think this is the BEST method.

Just remember that scene from Office Space... that printer is never coming back online

B Going with B here team. A destroyed or even shredded Disk Drive can still hold embedded strips of electronic DATA on it. even a shredded piece of HDD can still retrieve a small amount of data from the disk. Degaussing them will ensure that there is no data whatsoever.

BEST is to DESTROY. Crush into stardust!

Sybex Official Text Page 235: "The only way to ensure that there are not data remnants is through physical destruction of the media"

hmm Physical destruction is the best method to ensure no data remnants can be recovered. Drive wiping, degaussing, and purging are all methods of data erasure, but they may not be able to completely erase all data remnants. Physical destruction is the only method that can guarantee no data remains. so correct answer is D

B and C make sense for hard drives but since its a server hardware then the answer is D because it may contain SSD or bios or any ROM What is the best way to destroy electronic data? Shredding Another form of physical destruction, shredding may be the most secure and cost-effective way to destroy electronic data in any media that contain hard drives or solid state drives and have reached their end-of-life

Very poorly written. Either C or D. However SSD cannot be degaussed, only physical destruction. I would go with D for all circumstances.

CompTIA book does not talk about degaussing but it describes purging as the solution prior to disposal

Does purging apply to HDD?

Physical destruction will ensure and render the drive unusable to even attempt to access the data in it. Degaussing destroys the drive as well but bcos it renders the item inoperable, u can not tell whether it has completely removed all data. Purging is not enough...purging is just wiping. information can be retrieved using very good tools.

Purging data is meant to eliminate information from being feasibly recovered even in a laboratory environment. Conventional methods include degaussing (for magnetic media) and, where data is encrypted, using a method called Cryptographic Erasure to sanitize the cryptographic key rather than the related data. Since comptia doesn't say what type of drives they are, Purging will erase all

Not A because is not the best and data can be recovered. Not physical destruction since the team is disposing of the hardware in a none destruction so is the step prior to disposal. Purging data is meant to eliminate information from being feasibly recovered even in a laboratory environment. So C is the best answer.

Just another special CompTIA question, I picked physical destruction on my first go around and failed... probably pick it again this time.

C. Purging; Purge: a type of sanitization that provides effective protection from all recovery methods, including clean-room methods

It says "PRIOR TO DISPOSAL" so B is correct
