An orgAMzation has enabled a strict password policy for its IAM users. The orgAMzation is taking help from the IAM console to set the password policy. Which of the below mentioned rules cannot be specified by the user as a part of the policy?

1. A. Allow at least one lower case letter
2. B. Allow at least one number
3. C. Allow at least one non-alphanumeric character
4. D. Do not allow the user to use the password from the last three passwords

Correct Answer: D
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
One number

Which of the below mentioned options is a possible solution to avoid any security threat?

1. A. Use the IAM role and assign it to the instance.
2. B. Since the application is hosted on EC2, it does not need credentials to access S3.
3. C. Use the X.509 certificates instead of the access and the secret access keys.
4. D. Use the IAM based single sign between the AWS resources and the orgAMzation applicatio
