Question 270
A security change request has one specific goal: restore federated login after an identity provider rotates its SAML signing certificate. Which option should the engineer select?
Explanation
Correct Answer
IdP signing-certificate rollover is appropriate because Zscaler SAML assertion validation relies on a trusted current IdP signing certificate and configuration. That directly serves the stated need to restore federated login after an identity provider rotates its SAML signing certificate. Its boundary is that an expired or mismatched IdP signing certificate can block login despite correct user credentials.
Incorrect Answers
SAML identity provider is used to allow employees to sign in to Zscaler using their enterprise identity provider rather than a second password. It works because SAML federation carries signed authentication assertions from the configured identity provider to the service, but does not directly implement the named need for IdP signing-certificate rollover.
SAML assertion attributes is used to make department or group claims from a completed sign-in available as policy context. It works because the identity provider sends mapped claims in the SAML assertion for authorized policy use, but does not directly implement the named need for IdP signing-certificate rollover.
SCIM provisioning is used to keep users and groups provisioned without relying on an interactive login to create records. It works because SCIM exchanges user and group lifecycle changes through a provisioning integration, but does not directly implement the named need for IdP signing-certificate rollover.
