An engineer is setting up provisioning in VCS. Which two components must be in place? (Choose two.)

The no-charge provisioning option key must be installed on the VCS Control appliance to enable the provisioning service, as VCS provisioning is a licensed feature even though the key itself is free. Without this key, the provisioning subsystem on VCS Control cannot be activated.

One or more Movi option keys are required because each Movi (Jabber Video) client that connects via VCS provisioning consumes a Movi option key license - without them, clients cannot be provisioned.

An SMTP server is used for email-based notifications, not a prerequisite for enabling VCS provisioning itself.

An Active Directory service account may be used for LDAP integration but is not a required component specifically for enabling VCS provisioning.

An external AD server with secure connections is an optional LDAP integration component and is not a mandatory requirement for VCS provisioning setup.
