• Question 328:

  Which two parameters influence the total number of supported conference participants on a Cisco IOS XE router that has DSP modules? (Choose two.)

  A. voice codec
  B. session capacity of the PVDM module
  C. number of protocol data units
  D. software version Of the router
  E. license types
  A. voice codec
  B. session capacity of the PVDM module

  ---

  Explanation

  These are two parameters that influence the total number of supported conference participants on a Cisco IOS XE router that has DSP modules. A voice codec is a software algorithm that compresses and decompresses voice signals for transmission over a network. Different voice codecs have different bandwidth requirements and quality levels. A PVDM module is a hardware component that provides digital signal processing (DSP) resources for voice applications such as conferencing and transcoding. A PVDM module has a fixed session capacity, which is the maximum number of voice channels that it can support simultaneously.

• Question 329:

  Which configuration concept allows for high-availability on IM and Presence services in a UC environment?

  A. IM and Presence subclusters (configured on Cisco UCM)
  B. Presence Redundancy Groups (configured on Cisco Unified IM and Presence)
  C. IM and Presence subclusters (configured on Cisco Unified IM and Presence)
  D. Presence Redundancy Groups (configured on Cisco UCM)
  D. Presence Redundancy Groups (configured on Cisco UCM)
