Correct answer: Securely wipe, degauss, or physically destroy them and obtain a certificate of destruction
Secure wiping or physical destruction with documented certification prevents data recovery.
Question 2: Which data type is used to store whole numbers in programming?
- String
- Float
- Integer (Correct answer)
- Boolean
Correct answer: Integer
In programming, the `Integer` data type is specifically used to store whole numbers, which are numbers without any fractional or decimal components. Examples include -10, 0, and 1000. Other data types like `Float` store decimal numbers, `String` stores text, and `Boolean` stores true/false values.
Question 3: Which scan type uses valid login credentials to give a more accurate picture of a host's vulnerabilities?
- Credentialed scan (Correct answer)
- Banner grab
- Non-credentialed scan
- Ping sweep
Correct answer: Credentialed scan
