The correct answer is B. local power 5. A site survey must be conducted at the transmit power of the weakest client, so the survey AP mimics what the weakest device will actually experience. 12 mW ≈ 10.8 dBm ≈ 11 dBm.

Explanation

A site survey must be conducted at the transmit power of the weakest client, so the survey AP mimics what the weakest device will actually experience. 12 mW ≈ 10.8 dBm ≈ 11 dBm. On Cisco APs, 'local power 5' corresponds to approximately 11 dBm, which is the closest match to the 12 mW limit of the tracking tags. Using a higher power level (e.g., local power 1–4) would produce an overly optimistic survey that doesn't reflect the real coverage the low-power tags will see. Configuring the survey AP to match the weakest client ensures the coverage map is accurate for all devices in the deployment.
