Question

A customer is using Cisco MCU cascading with Cisco TelePresence Conductor 3.0 and Cisco Video Communication Server in B2BUA mode. How does Cisco TelePresence Conductor choose the bridges in a conference cascading scenario?

Options

  • AIt chooses one bridge from each available bridge pool, to optimize load balancing
  • BIt tries to use a bridge in the preferred bridge pool first, then it cascades to bridges in other bridge
  • CIt tries to use a bridge in the preferred bridge pool first, then it cascades to bridges in the same
  • DIt chooses the first available bridge that meets all conference resource requirements, regardless of

Why each option

Cisco TelePresence Conductor selects bridges in a cascading scenario by preferring a bridge in the designated preferred pool first, then expanding to bridges in the same pool before going elsewhere.

AIt chooses one bridge from each available bridge pool, to optimize load balancing

Conductor does not select one bridge from each available pool by default; it targets a preferred pool first rather than spreading load across all pools simultaneously.

BIt tries to use a bridge in the preferred bridge pool first, then it cascades to bridges in other bridge

Cascading to bridges in other pools is a secondary fallback behavior, not the primary cascade path, which stays within the same pool first.

CIt tries to use a bridge in the preferred bridge pool first, then it cascades to bridges in the sameCorrect

Conductor's bridge selection logic prioritizes the preferred bridge pool for a conference, and when additional capacity is needed for cascading, it expands within that same pool before looking at other pools. This behavior ensures resource locality and predictable load distribution within a defined pool boundary.

DIt chooses the first available bridge that meets all conference resource requirements, regardless of

Conductor does not ignore pool membership and simply pick the first available bridge; pool preference is a deliberate part of the selection algorithm.
