Explanation

A Cisco Unified CM group is a prioritized list of up to three Cisco Unified CM servers (primary, secondary, tertiary) assigned to devices. It provides two key features: (D) redundancy - if the primary CM server becomes unavailable, phones automatically fail over to the next server in the group; and (E) call load balancing - phones registering to the group are distributed across the CM servers to spread processing load. Option A is incorrect because CM groups operate within a single cluster, not across clusters. Option B is incorrect as system IP address is not a function of a CM group. Option C is incorrect because a CM group supports up to three servers, not two.
