C. On both a gatekeeper and a gateway

Correct Answer: B
Explanation/Reference:
Explanation:
To allow gatekeepers to make intelligent call routing decisions, the gateway reports the status of its resource availability to its gatekeeper. Resources that are monitored are DS0 channels and DSP channels.
The gateway reports its resource status to the gatekeeper with the use of RAS Resource Availability Indication (RAI). When a monitored resource falls below a configurable threshold, the gateway sends an RAI to the gatekeeper that indicates that the gateway is almost out of resources. When the available resources then cross above another configurable threshold, the gateway sends an RAI that indicates that the resource depletion condition no longer exists.
This feature was included in Cisco IOS Software Release 12.0(5)T on the Cisco AS5300 gateway, and Cisco IOS Software Release 12.1(1)T for other gateways in H.323 version 2 http://www.cisco.com/en/US/tech/tk1077/technologies_tech_note09186a0080093f67.shtml
