Which two features are advantages of deploying a cluster over WAN? (Choose two.)

The correct answer is A. shared line appearances C. extension mobility within the cluster. A Cisco Unified Communications Manager cluster over WAN (also called a multi-site WAN deployment with centralized call processing) allows all phones across all sites to be members of the same cluster. This enables shared line appearances (A) - multiple phones at different sites…

Explanation

A Cisco Unified Communications Manager cluster over WAN (also called a multi-site WAN deployment with centralized call processing) allows all phones across all sites to be members of the same cluster. This enables shared line appearances (A) - multiple phones at different sites can share the same directory number and ring simultaneously. It also enables extension mobility within the cluster (C) - users can log in to any IP phone at any site and retrieve their profile. Centralized DSP resources (B) are a benefit of centralized SRST/gateway design, not a cluster-over-WAN feature. Scalability to 20 sites (D) is not a defined limit for this deployment model. Failover to CME (E) is a separate SRST/CME feature, not a cluster advantage.
