AWS Certified SysOps Administrator – Associate (legacy) — Question 608

ABC has three AWS accounts. They have created separate IAM users within each account.
ABC wants a single IAM login URL such as https://abc.signin.aws.amazon.com/console/ for use by IAM users in all three accounts.
How can this be achieved?

Answer options

• A. Merge all the accounts with consolidated billing
• B. Create the S3 bucket with an alias name and use the redirect rule to forward requests to various accounts
• C. Create the same account alias with each account ID
• D. It is not possible to have the same IAM account login URL for separate AWS accounts

Correct answer: D

Explanation

AWS IAM account aliases must be globally unique across all of AWS, meaning that no two accounts can share the exact same alias. Because of this restriction, it is impossible to configure a single custom sign-in URL for three different AWS accounts. Therefore, users must use the unique sign-in URL associated with their specific AWS account.
