Question

A company that uses AWS Organizations is using AWS IAM Identity Center to administer access to AWS accounts. A security engineer is creating a custom permission set in IAM Identity Center. The company will use the permission set across multiple accounts. An AWS managed policy and a customer managed policy are attached to the permission set.

When assigning a permission set across multiple accounts, Identity Center attempts to attach the fails. Creating the same customer managed policy with identical name and permissions in every target account resolves the issue. Option B increases complexity. Option C does not address the root cause. Option D violates Identity Center management best practices. AWS documentation clearly states that customer managed policies must be present in all accounts where permission sets are applied.
