Question 5
A company is retiring old workstations and needs a certificate of destruction for all hard drives.
Which of the following would be BEST to perform on the hard drives to ensure the data is unrecoverable? (Select TWO).
  1. Standard formatting
  2. Drilling
  3. Erasing
  4. Recycling
  5. Incinerating 
  6. Low-level formatting
Correct answer: BE
Explanation:
Drilling and incinerating are physical destruction methods that make the data on hard drives unrecoverable. Standard formatting, erasing and low-level formatting are logical methods that can be reversed with data recovery tools. Recycling is not a destruction method at all. Verified Reference:https://www.comptia.org/blog/what-is-a-certificate-of-destructionhttps://www.comptia.org/certifications/a
