You have asked your users to avoid using passwords that use letters only. Which of the following policies would help enforce this?

Question

Password complexity requirements

Enforce password history

Minimum password length

Maximum password age.

Answer 1

The policy that would help enforce the requirement to avoid using passwords that use letters only is Password complexity requirements.

Password complexity requirements typically include stipulations that passwords must contain a mix of character types, such as uppercase letters, lowercase letters, numbers, and special characters. This would effectively prevent users from creating passwords that consist of letters only.

The other options (enforce password history, minimum password length, maximum password age) do not directly address the issue of character variety in passwords.
