Refer to the exhibit. You have created a profile in the Cisco Unified Communications Manager for a new Telepresence room with the MAC address 00:19:AA:04:4E:AE. You log into the Cisco Telepresence Manager and you enter the Discovery Service and select the Discover Rooms button. When you check the Rooms listing under the Cisco Telepresence Manager, you do not see the new room listed. You then inspect the DiscoveryMgr_audit.log file. Which is the cause of the problem?
A.
The device profile for the Cisco CTS-3000 codec was set up with the incorrect CiscoTelepresence system type and this is causing the Cisco Telepresence Manager to ignore and delete the profile when it detects it is incorrect.
B.
The device profile for the Cisco CTS-3000 codec was incomplete and this is causing the CiscoTelepresence Manager to ignore and delete the profile when it detects it is incorrect.
C.
The device profile for the Cisco CTS-3000 codec was set up, but the device profile did not have a directory number assigned to it, therefore the device is unregistered.
D.
You have not created an application user for the CiscoTelepresence endpoint in the Unified CM.
E.
You have not assigned the MAC address of thisTelepresence device to the Cisco Telepresence Manager’s application user account in the Unified CM.
F.
The CiscoTelepresence Manager has an existing room with the MAC address
00:19:AA:04:4E:AE. This will prevent the Cisco Telepresence Manager from saving this room
in its database.
