Question

An engineer deployed two Cisco TelePresence MCU 5320 Servers in a stacked deployment. Each server has 20 HD Port licenses installed. During a 20-party 720p 30-fps conference, eight additional parties attempt to join the conference. What are the two characteristics of this scenario? (Choose two.)

  • AThe Cisco 5320 MCU in a stacked deployment is capable of supporting 720p 30-fps without
  • BWhen the 21st party joins, the call is declined because all ports are already in use on the first
  • CThe 21st party is cascaded into the conference, and the 22nd and additional parties are declined
  • Dthe additional conference attendees are able to join the conference in the same manner and
  • EThe Cisco TelePresence MCU 5320 is capable of supporting a maximum of twenty 720p 30-fps
  • FThe conference is auto-balanced and resources are re-optimized via the MCU API. Parties 1

Why each option

In a stacked Cisco TelePresence MCU 5320 deployment with 40 total HD port licenses, all 28 parties can join the conference, with the first 20 hosted on the primary MCU and the remaining 8 automatically cascaded to the second MCU.

AThe Cisco 5320 MCU in a stacked deployment is capable of supporting 720p 30-fps without

While the MCU 5320 stacked deployment does support 720p 30-fps, this option is incomplete and does not address the overflow handling behavior central to the scenario.

BWhen the 21st party joins, the call is declined because all ports are already in use on the first

The 21st party is not declined - the stacking feature cascades overflow participants to the second MCU rather than rejecting them.

CThe 21st party is cascaded into the conference, and the 22nd and additional parties are declined

Only the 21st party being cascaded while the 22nd and subsequent parties are declined is incorrect - the combined 40-port stacked capacity accommodates all 28 participants.

Dthe additional conference attendees are able to join the conference in the same manner andCorrect

In a stacked MCU deployment, both units function as a single logical resource pool, so the additional attendees experience the same conferencing quality and joining behavior as the initial 20 participants. The stacking feature is specifically designed to extend capacity beyond a single MCU's limit without degrading the participant experience.

EThe Cisco TelePresence MCU 5320 is capable of supporting a maximum of twenty 720p 30-fps

The 20-port HD maximum applies to a single standalone MCU 5320 - in a stacked deployment, the combined capacity is 40 HD ports.

FThe conference is auto-balanced and resources are re-optimized via the MCU API. Parties 1

Cisco MCU stacking documentation does not describe an auto-balancing mechanism via the MCU API - cascading is automatic based on port capacity, not an API-driven rebalancing operation.

GThe additional eight parties are cascaded into the conference on the second 5320 MCU, and anCorrect

When the primary MCU 5320 reaches its 20-port capacity, the stacking feature automatically cascades overflow participants to the second MCU 5320. All eight additional parties can join because the combined stacked capacity of 40 HD ports exceeds the 28 total participants in this scenario.
