How does a Cisco Unified Wireless network respond to Wi-Fi channel overlap?

Question

Options

• AIt alternates automatically between 2.4 GHz and 5 GHz on adjacent access points
• BIt allows the administrator to assign channels on a per-device or per-interface basis.
• CIt segregates devices from different manufacturers onto different channels.
• DIt analyzes client load and background noise and dynamically assigns a channel.

• A
  2% (1)
• B
  8% (4)
• C
  4% (2)
• D
  87% (46)

Explanation

Cisco's Radio Resource Management (RRM) feature continuously monitors RF conditions - including client load, interference, and background noise - and dynamically assigns the least congested channel to each access point, which is exactly what option D describes. Option A is wrong because alternating frequencies between adjacent APs is not how channel overlap is handled; frequency band selection and channel assignment are separate concerns. Option B is wrong because while manual channel assignment is possible, it's not the defining response to overlap - the power of Cisco's unified architecture is its automated optimization. Option C is wrong because channel assignment is based on RF conditions, not device manufacturer.

Memory tip: Think of RRM as a "smart DJ" - it's always listening to the room (background noise) and watching the crowd (client load) to pick the best channel automatically, so no one has to manually manage the playlist.
