What is the purpose of the Zscaler Client Connector providing the authentication token to the...

After ZIA validates the user's authentication, Client Connector provides the authentication token to the Client Connector Portal so the device can be registered. That registration ties the authenticated user, device, and enrollment state together for policy, posture, and service entitlement decisions. Option C (To enable the portal to register the user’s device and pass the registration to Zscaler Internet Access) is correct because the token enables device registration and passes that registration to ZIA.

Why the other options are incorrect:

A. To bypass multifactor authentication (MFA) during the enrollment process: Bypassing MFA would weaken assurance. The token exchange registers the device/session with Zscaler; it is not a shortcut around the IdP or MFA policy.

B. To immediately grant the user access to Zscaler Private Access resources: A valid login proves identity, but it does not grant every private resource. ZPA still applies access policy, posture, and app-segment entitlement.

D. To share the authentication token with the SAML IdP to validate the user session: The SAML IdP issues the authentication assertion. Device registration after that belongs to the Zscaler Client Connector Portal and ZIA token workflow.
