An engineer is designing a wireless deployment for a university auditorium. Which two features can be used to help deal with the issues introduced by high AP count? (Choose two.)

TPC (Transmit Power Control) is a Cisco RRM mechanism that automatically reduces AP transmit power in dense environments to minimize co-channel interference between neighboring APs, preventing the coverage overlap and contention that comes from having many APs in close proximity.

LSS (Location-based Services System) is a location tracking and services framework and has no function related to managing RF interference or channel assignment in dense deployments.

RXSOP (Receive Start of Packet) raises the minimum RSSI threshold at which an AP begins processing a packet, which can filter out weak interferers in dense environments, but it is not one of the two coordinated RRM features specifically designed to address inter-AP interference from high AP count.

TSPEC (Traffic Specification) is a QoS admission control element used for voice and video stream negotiation and does not address RF interference or channel planning issues introduced by deploying many APs.

DFS (Dynamic Frequency Selection) expands the usable 5GHz channel pool by enabling radar-avoidance DFS channels, giving RRM significantly more non-overlapping channels to distribute across a high-density AP deployment and reducing co-channel contention at a system level.
