A user is trying to create a list of IAM users with the AWS console. When the IAM users are created which of the below
mentioned credentials will be enabled by default for the user?

A.
IAM access key and secret access key

B.
IAM X.509 certificates

C.
Nothing. Everything is disabled by default

D.
IAM passwords

Explanation:
Newly created IAM users have no password and no access key (access key ID and secret access key). If the user needs
to administer your AWS resources using the AWS Management Console, you can create a password for the user. If the
user needs to interact with AWS programmatically (using the command line interface (CLI), the AWS SDK, or servicespecific APIs), you can create an access key for that user. The credentials you create for users are what they use to
uniquely identify themselves to AWS.
