After creating a new IAM user which of the following must be done before they can successfully make API
calls?
A.
Add a password to the user.
B.
Enable Multi-Factor Authentication for the user.
C.
Assign a Password Policy to the user.
D.
Create a set of Access Keys for the user.
Explanation:
http://docs.aws.amazon.com/IAM/latest/UserGuide/Using_SettingUpUser.html
C: By default, a brand new IAM user has no password and no access key (neither an access key ID nor a secret access key)—no credentials of any kind. You must create the type of credentials for an IAM user based on what the user will be doing.
but it is not always the best to use access keys so rather give user permissions to make API calls
