Cisco Implementing Cisco Unified Communications Voice over IP and QoS v8.0 (CVOICE v8.0) Sample Questions:

1. You are configuring a network to support voice to the PSTN. One important aspect to the configuration is to be able to determine the individual slot, subunit, and port number from the gateway endpoint identifier. Which signaling protocol is appropriate for this situation?

A) SCCP
B) MGCP
C) SIP
D) H.323

2. DRAG DROP
The voice gateway selects an inbound VoIP dial peer by matching the information elements in the setup message with the dial peer attributes. From the list on the left, drag the elements to the right and drop them in the order in which a voice gateway matches inbound calls. Not all options are used.

3. In a voice gateway, the configured codec complexity of the DSPs on a voice card can be changed. What is the impact on the DSPs if high codec complexity is configured?

A) Lower codec complexity supports the fewest number of voice channels, provided that the lower complexity is compatible with the particular codecs that are in use.
B) The codec complexity affects call density, which is the number of calls that are reconciled on the DSPs. This results in lower call density when high complexity is configured.
C) The DSP will process codecs that support high complexity transparently and shift to flex mode for those codecs that are not high complexity.
D) With higher codec complexity, more calls can be processed.
