not sure about the answers

how bout you sniff theez nutz Cisco?

Why are there so many wireless questions?

one of those: is the cup half empty or half full questions

From Cert guide, nothing about sensor in the book. Monitor: The AP does not transmit at all, but its receiver is enabled to act as a dedicated sensor. The AP checks for IDS events, detects rogue access points, and determines the position of stations through location-based services. Sniffer: An AP dedicates its radios to receiving 802.11 traffic from other sources, much like a sniffer or packet capture device. The captured traffic is then forwarded to a PC running network analyzer software such as Wildpackets OmniPeek or WireShark, where it can be analyzed further.

wth air-quality? Ci$co is selling air purifier now?

Don't think that "sensor" is an official AP mode, but by elimination and using below sources i came to this result (please correct if wrong) Monitor It supports analytics for wireless performance testing It supports software that analyzes wireless frames on a remote device Sensor It enables RFID-tag location tracking It enables air-quality data and interference detection across all enabled devices Sniffer it supports real time wifi client troubleshooting when network engineers are offline it captures and forwards packets on a specific wireless channel https://community.cisco.com/t5/wireless/access-point-modes/td-p/1154701 https://study-ccnp.com/cisco-wireless-access-point-ap-modes-explained/ https://networklessons.com/cisco/ccna-200-301/cisco-wireless-ap-modes

Sniffer, huh? Maybe some folks at Cisco could do with one of those. Might help them sniff out the BS that's clearly leaking through into the CCNA exam.

Below is just one article I found. But I could not find anything about "sensor mode" https://ipcisco.com/lesson/wireless-access-point-modes/
