Which two of these are characteristics of a Cisco Unified Communications Manager software conference resource? (Choose two)

Question

Options

• AIt supports both unicast and multicast audio streams
• BIt supports only unicast audio streams
• CThe number of participants is based on the number of DSP resources available
• DAny combination of G.711 mu-law, G.711 a-law, or wideband audio streams may be connected.
• EIt supports any combination of codec types.

• A
  2% (1)
• B
  93% (40)
• C
  5% (2)

Explanation

A CUCM software conference resource runs on the CUCM server itself (as opposed to hardware DSP-based resources on media servers). (B) It supports ONLY unicast audio streams - multicast is not supported by the software conference bridge; hardware-based resources (like those on Cisco IOS gateways or media servers) are required for multicast. (D) Any combination of G.711 mu-law, G.711 a-law, or wideband audio streams may be connected - the software conference bridge natively supports these specific codec types and can mix them. It does NOT support arbitrary codec combinations (ruling out E), so codecs like G.729 require a transcoder. The number of conference participants is limited by server CPU/memory, not DSP resources (ruling out C).
