IP Services

SIP-based Call Admission Control must be configured in the Cisco WLC GUI, and SIP call-snooping ports have already been configured.

Which two actions must be completed next?

Choose two
  • A Set the QoS level to silver or greater for voice traffic.
  • B Configure two different QoS roles for data and voice traffic.
  • C Enable Media Session Snooping on the WLAN.
  • D Set the QoS level to platinum for voice traffic.
  • E Enable traffic shaping for the LAN interface of the WLC.
Explanation

Cisco WLC SIP-based CAC requires the voice WLAN to use the Platinum QoS profile and requires call/media session snooping to be enabled on the WLAN so the controller can detect SIP call establishment and enforce admission control. Cisco documentation explicitly identifies Platinum QoS as a prerequisite for CAC and SIP snooping as required for SIP-based CAC; Silver is not sufficient, and separate QoS roles or LAN traffic shaping are not mandatory steps for this feature.
