Question

A) They should be changed only by the administrator.
B) They must be no more than eight characters in length.
C) They are requested by CAPTCHAs.
D) They are most secure when they consist of letters, numbers, and special characters.
E) They are required to be unique.

Answer 1

User passwords are most secure when they consist of letters, numbers, and special characters. They should not be limited to eight characters, changed by an administrator, or requested by CAPTCHAs. While unique passwords are recommended, they are not required.

The correct answer is D) They are most secure when they consist of letters, numbers, and special characters.

Step-by-step explanation:

The correct answer is D) They are most secure when they consist of letters, numbers, and special characters. Passwords that incorporate a combination of uppercase and lowercase letters, numbers, and special characters are generally more difficult to guess or crack.

Option A is incorrect because users should have the ability to change their passwords on their own without relying on an administrator. Option B is incorrect because there is no specific limit on the length of a password, and longer passwords are generally considered more secure.

Option C is incorrect because CAPTCHAs are used to verify that a user is human, not specifically to request passwords. Option E is incorrect because while it is good practice to have unique passwords for different accounts, it is not a requirement.
