Which Applications Should Connect to a Leaf Cluster in Cisco Unified Communications Manager Session Management Edition Deployment?

BE.

The deployment of a Unified CM Session Management Edition enables commonly used applications, such as conferencing or videoconferencing to connect directly to the session management cluster, which reduces the overhead of managing multiple trunks to leaf systems.

Unified CM Session Management Edition supports the following applications: Unity, Unity Connection.

Meeting Place, Meeting Place Express.

SIP and H.323-based video conferencing systems.

Third Party voice mail systems.

Fax servers.

Cisco Unified Mobility.

The following applications must connect to the leaf cluster: Unified Contact Centre, CUCM, Unified Contact Centre Express.

Cisco Unified Presence Server.

Attendant Console.

Manager Assistant.

IP IVR.

Cisco Voice Portal.

In a Cisco Unified Communications Manager Session Management Edition (SME) deployment, leaf clusters are used to provide redundancy and load balancing capabilities. Leaf clusters are a group of Cisco Unified Communications Manager (CUCM) clusters that are connected through a SIP trunk.

To answer the question, we need to identify the applications that must be connected to a leaf cluster. These applications are typically integrated with CUCM and use it for call control.

The correct answers are E. Cisco Unified Communications Manager and F. fax servers.

Explanation:

A. Cisco Unified Meeting Place is an audio and video conferencing solution that integrates with CUCM. However, it is not mandatory for Meeting Place to be connected to a leaf cluster. It can be connected to any CUCM cluster within the deployment.

B. Cisco Unified Contact Center Express is a contact center solution that integrates with CUCM. Similar to Meeting Place, it is not mandatory for Contact Center Express to be connected to a leaf cluster. It can be connected to any CUCM cluster within the deployment.

C. H.323-based video conferencing systems are not integrated with CUCM. They use a separate gatekeeper for call control.

D. Cisco Unity is a voicemail and unified messaging solution that integrates with CUCM. However, it is not mandatory for Unity to be connected to a leaf cluster. It can be connected to any CUCM cluster within the deployment.

E. Cisco Unified Communications Manager (CUCM) is the call control component in a Cisco UC deployment. CUCM must be connected to a leaf cluster to provide redundancy and load balancing capabilities.

F. Fax servers, such as Cisco Fax Server, integrate with CUCM and use it for call control. Therefore, they must be connected to a leaf cluster for redundancy and load balancing purposes.

In summary, only Cisco Unified Communications Manager and fax servers must be connected to a leaf cluster in a Cisco Unified Communications Manager Session Management Edition deployment.
