SCIM is the open standard for automated identity provisioning and attribute synchronization. It keeps user, group, and department information updated from the IdP into Zscaler without requiring manual edits or waiting for a new SAML login. Option C (SCIM) is correct because SCIM handles automatic updates to identity attributes.

Why the other options are incorrect:

A. Import: Import is a one-time or manual data-load action. SCIM provides ongoing automated provisioning and synchronization.

B. LDAP Sync: LDAP queries read structured directory data from Active Directory, such as users, groups, and permissions.

D. SAML: SAML provides browser-based federation by carrying signed assertions from the identity provider to the service provider.
