What are two valid privilege levels for subscribers on Cisco Unity Express? (Choose two.)

Superuser is a valid CUE subscriber privilege level that grants elevated administrative rights within the voicemail system, allowing the subscriber to manage greetings, mailboxes, and system-level settings.

Admin is not a recognized subscriber privilege level in Cisco Unity Express; it is a role used in other Cisco platforms but does not exist in the CUE subscriber privilege model.

Guest is not a defined privilege level for CUE subscribers; CUE does not use guest-level access when configuring subscriber accounts.

Broadcast is a valid CUE subscriber privilege level that permits the subscriber to send broadcast messages to all mailboxes in the system.

Root is a Linux/Unix operating system concept and is not a valid or configurable privilege level within Cisco Unity Express subscriber settings.
