You are the administrator for your company’s UCM network. Examine the exhibit below, and answer the
question:

Which of the following is not true of the end-user configuration?

A.
The end user’s primary extension is 65501.

B.
The end user is not configured to control a desk phone from Cisco Jabber.

C.
The end user can log in to a temporary IP phone as if it were a permanent workstation.

D.
The end user cannot currently use Cisco Jabber for IM and Presence information.

Explanation:
The end user cannot log in to a temporary IP phone as if it were a permanent workstation, because Extension
Mobility has not been configured for this user. Extension Mobility enables a user who works at a shared
workstation to log in to and use an IP phone as if the phone were at a permanent workstation. For example, if
the user programmed speed-dial options on an IP phone, those options would be stored in the user’s device
profile and made available to the user at any IP phone that is subscribed to Extension Mobility, as long as the
user is able to log in to that IP phone.
In order for an Extension Mobility user to properly log in to and log out of an IP phone, both the IP phone and
the device profile that stores the user’s preferences must be subscribed to the Extension Mobility service. In
this scenario, no device profile has been associated with the end user. In addition, if the IP phone is not
subscribed to Extension Mobility, the user will not be able to log in to Extension Mobility from the IP phone and
an error message will appear on the IP phone’s display. In addition, if the Extension Mobility Uniform Resource
Locator (URL) is not correctly configured in UCM, the user will not be able to log in to Extension Mobility from
the IP phone and an error message will appear on the IP phone’s display.
The end user cannot currently use Cisco Jabber for IM and Presence information. Cisco Jabber relies on Cisco
Unified Presence (CUPS) and the Extensible Messaging and Presence Protocol (XMPP) for instant messaging
(IM) and Presence functionality. However, in this scenario, Cisco Jabber is unable to connect to a CUPS server.
There is not enough information in this scenario to determine whether the end user has been configured to
control a desk phone from Cisco Jabber. Based on the Connection Status window, you can determine only that
the Cisco Jabber client is not currently connected to a desk phone.
The end user’s primary extension is 65501. The 65501 value has been configured in the Primary Extension
field.
