[All AWS Certified Security - Specialty Questions]

A company uses SAML federation with AWS Identity and Access Management (IAM) to provide internal users with SSO for their AWS accounts. The company's identity provider certificate was rotated as part of its normal lifecycle. Shortly after, users started receiving the following error when attempting to log in:

"Error: Response Signature Invalid (Service: AWSSecurityTokenService; Status Code: 400; Error Code: InvalidIdentityToken)"

A security engineer needs to address the immediate issue and ensure that it will not occur again.

Which combination of steps should the security engineer take to accomplish this? (Choose two.)

A. Download a new copy of the SAML metadata file from the identity provider. Create a new IAM identity provider entity. Upload the new metadata file to the new IAM identity provider entity.
B. During the next certificate rotation period and before the current certificate expires, add a new certificate as the secondary to the identity provider. Generate a new metadata file and upload it to the IAM identity provider entity. Perform automated or manual rotation of the certificate when required.
C. Download a new copy of the SAML metadata file from the identity provider. Upload the new metadata to the IAM identity provider entity configured for the SAML integration in question.
D. During the next certificate rotation period and before the current certificate expires, add a new certificate as the secondary to the identity provider. Generate a new copy of the metadata file and create a new IAM identity provider entity. Upload the metadata file to the new IAM identity provider entity. Perform automated or manual rotation of the certificate when required.
E. Download a new copy of the SAML metadata file from the identity provider. Create a new IAM identity provider entity. Upload the new metadata file to the new IAM identity provider entity. Update the identity provider configurations to pass a new IAM identity provider entity name in the SAML assertion.

Reason for not choosing A and D; It is not correct creating a --"new"-- IAM identity provider --"entity"-- , cos that would require updating all IAM roles that --"trust"-- the ---"old identity provider entity " ---.

B and C provides a viable solution for outdate meta data or invalid certificates used during the authentication process for SAML.
