Which type of user in Cisco Unified Communications Manager has an interactive login?

A.
administrator

B.
end user

C.
application user

D.
phone user

Explanation:
End users — End users are associated with an individual and have an interactive login. End users
can have administrative roles based on the user group role configuration.
Application users — Application users are associated with applications such as Cisco Unified
Attendant Console, Cisco Unified Contact Center Express (UCCX), or Cisco Unified Manager
Assistant. The mentioned applications need to authenticate with CUCM, but application users do
not have the ability to interactively log in. Application users are leveraged for internal process-level
communications between applications.
