A. B. C. D. E. F.BE.
In a Cisco Unified Communications Manager Session Management Edition (SME) deployment, the Session Management Edition provides call control for multiple Cisco Unified Communications Manager (CUCM) clusters. The CUCM clusters are connected to the Session Management Edition by using SIP trunks.
When it comes to applications that need to be connected to a leaf cluster in this deployment model, there are two key considerations:
The leaf cluster is a CUCM cluster that is directly connected to the Session Management Edition. It serves as the primary point of entry for calls into and out of the SME deployment.
Applications that require access to call control services, such as call routing, call admission control, and call processing, must be connected to a CUCM cluster in the SME deployment.
Based on these considerations, the two applications that must be connected to a leaf cluster in a Cisco Unified Communications Manager Session Management Edition deployment are:
B. Cisco Unified Contact Center Express: This application requires call control services for call routing and processing. It should be connected to a CUCM cluster in the SME deployment.
E. Cisco Unified Communications Manager Attendant Console: This application also requires call control services for call routing and processing. It should also be connected to a CUCM cluster in the SME deployment.
The other options listed in the question do not necessarily require access to call control services from a CUCM cluster in the SME deployment. Here is a brief explanation of each:
A. Cisco Unified Meeting Place: This application provides audio and web conferencing services. It does not necessarily require call control services from a CUCM cluster in the SME deployment, as it can use SIP trunks to connect to the Session Management Edition directly.
C. H.323-based video conferencing systems: These systems use H.323 protocols for call signaling and media transport. They can connect to the Session Management Edition directly using SIP trunks, and do not require call control services from a CUCM cluster.
D. Cisco Unity: This application provides voicemail and unified messaging services. It can be connected to a CUCM cluster in the SME deployment, but it does not necessarily require access to call control services.
F. Fax servers: These servers provide fax services over IP networks. They can be connected to the Session Management Edition directly using SIP trunks, and do not require call control services from a CUCM cluster.
