You administer the VoIP network above.
The VoIP network is divided into four partitions. Two of the partitions are in Los Angeles, and two are in New
York.
Which of the following are true? (Choose two.)

A.
The dn 6545 is not shared.

B.
The dn 6545 is shared within LA1000PT.

C.
The dn 6545 is shared between LA1000PT and LA2000PT.

D.
The dn 6546 is not shared.

E.
The dn 6546 is shared within NY1000PT.

F.
The dn 6546 is shared between NY1000PT and NY2000PT.

Explanation:
The directory number (dn) 6546 is not shared. However, the dn 6545 is shared within the LA1000PT partition.
You can segregate a Voice over IP (VoIP) network into partitions in order to facilitate the use of different route
patterns for different subsets of users. For example, if users in the LA1000PT partition should not be allowed to
make long distance phone calls, you can restrict long distance phone calls in LA1000PT without affecting the
route patterns in the other three partitions.Any dn that is configured in more than one partition will not be shared between the two partitions, because the
partitions are treated as individual VoIP networks. Because a dn can be configured in more than one partition,
the same dn can present different line identification information depending on its configuration within the given
partition. By contrast, a dn that is configured on multiple devices within the same partition is considered to be a
shared dn, or a shared line.
The dn 6545 has been configured in all four partitions of the VoIP network. However, dn 6545 has been
configured multiple times in only two of the partitions: LA1000PT and NY2000PT. Therefore, dn 6545 has been
configured as a shared line in both the LA1000PT partition and the NY2000PT partition of the VoIP network. In
Cisco Unified Communications Manager (UCM) Administration, you can configure a dn as a shared line by
navigating to the device on which you want the shared line to appear and adding the dn for the shared line to
that device.
The dn 6546 has been configured in two of the four partitions of the VoIP network. However, dn 6546 has not
been configured more than once in the same partition. The dn 6546 is configured on one device in the
LA2000PT partition and on one device in the NY1000PT partition. Because it is not configured more than once
within the same partition, dn 6546 is not a shared dn.
