300-425 · Question #103

An engineer performs a Layer 1 survey by using Metageek Chanatyzer only on the current operating channel. Which operating mode is configured for a Cisco CleanAir AP?

The correct answer is A. local. A Cisco CleanAir AP in local mode performs spectrum analysis exclusively on its assigned serving channel, matching the single-channel Chanalyzer survey described.

Why each option

A Cisco CleanAir AP in local mode performs spectrum analysis exclusively on its assigned serving channel, matching the single-channel Chanalyzer survey described.

AlocalCorrect

In local mode, a CleanAir-enabled AP simultaneously serves wireless clients and performs CleanAir interference detection confined to its assigned operating channel. Because the AP does not perform off-channel scanning for spectrum purposes, Chanalyzer receives Layer 1 spectrum data only for the channel the AP is currently serving, which is exactly the single-channel survey behavior described in the question.

Bsniffer

Sniffer mode captures 802.11 frame data and forwards packets to a protocol analyzer such as Wireshark; it does not provide Layer 1 RF energy or spectrum data to Chanalyzer.

Cmonitor

Monitor mode dedicates the AP to scanning all channels for rogue detection and wireless IDS functions, not to single-channel spectrum analysis on one serving channel.

DSE-connect

SE-Connect mode connects the AP to an external spectrum analyzer like Chanalyzer for dedicated spectrum analysis, but in this mode the AP stops serving clients and is not restricted to a single current operating channel.
