  • B. Allow at least one number
  • C. Allow at least one non-alphanumeric character

Answer: D

Explanation:
AWS IAM allows an orgAMzation to create multiple users and provide them access to various AWS services. By default when the user is created, he does not have password enabled and can not login to AWS console. If the orgAMzation wants to allow the users to login to AWS console, they can enable password for each user. It is required that IAM users follow certain guidelines to set their IAM login password. For this IAM provides root account owner to setup passwrod policy. The password policy also lets the specify whether all IAM users can change their own passwords. As part of policy, orgAMzation can specify that passwords for IAM users must be of a certain minimum length, must include certain characters, and a few more criteria such as below.
One upper/ lower or both letters One alpha numeric
