When configuring Auto TX Power control on an AP radio, which two statements best describe how the radio responds? (Choose two.)

When configuring Auto TX Power control on an AP radio, which two statements best describe how the radio responds? (Choose two.)
A . When the AP detects any other wireless signal stronger that -70 dBm, it will reduce its transmission power until it reaches the minimum configured TX power limit.
B . When the AP detects PF Interference from an unknown source such as a cordless phone with a signal stronger that -70 dBm, it will increase its transmission power until it reaches the maximum configured TX power limit.
C . When the AP detects any wireless client signal weaker than -70 dBm, it will reduce its transmission power until it reaches the maximum configured TX power limit.
D . When the AP detects any interference from a trusted neighboring AP stronger that -70 dBm, it will reduce its transmission power until it reaches the minimum configured TX power limit.

Answer: A, D

Explanation:

According to the web search results, Auto TX Power control is a feature that allows the AP to automatically adjust its transmission power based on the RF environment. The goal is to minimize interference and optimize coverage cells for roaming. When the AP detects any other wireless signal stronger than -70 dBm, it means that there is a potential source of interference nearby, so it will reduce its transmission power until it reaches the minimum configured TX power limit. This will reduce the interference and improve coexistence with other devices. When the AP detects any interference from a trusted neighboring AP stronger than -70 dBm, it means that there is a high density of APs in the area, so it will also reduce its transmission power until it reaches the minimum configured TX power limit. This will balance the load and avoid overlapping coverage areas.
