Is SCIM mandatory for ZIA?

SCIM is useful for automated provisioning, group synchronization, and lifecycle management, but it is not mandatory for ZIA authentication. ZIA can authenticate users through SAML and other supported identity methods even if SCIM is not deployed. Option A (No) is correct because SCIM is optional for ZIA, not required.

Why the other options are incorrect:

B. Depends: Depends would only be acceptable if the question were asking for design preference. The direct fact tested here is that SCIM is not mandatory for ZIA.

C. Yes: Yes would make SCIM a hard requirement. ZIA can authenticate and apply policy without mandatory SCIM provisioning.

D. Maybe: Maybe is not a platform behavior. SCIM is optional for ZIA, even though it is useful for automated lifecycle management.
