N10-005 Question #726: Real Exam Question with Answer & Explanation
The correct answer is C: Channel bonding. Channel bonding combines two adjacent 20 MHz wireless channels into a single 40 MHz channel, effectively doubling the available bandwidth on the wireless network.
Question
An administrator would like to get more speed out of a wireless network. The administrator decides to configure the AP with a frequency width of 40MHz. Which of the following features is the administrator MOST likely using?
Options
- AMIMO
- BAP isolation
- CChannel bonding
- DBurst mode
Explanation
Channel bonding combines two adjacent 20 MHz wireless channels into a single 40 MHz channel, effectively doubling the available bandwidth on the wireless network.
Common mistakes.
- A. MIMO (Multiple Input Multiple Output) uses multiple antennas to transmit and receive several data streams simultaneously, improving throughput through spatial multiplexing rather than by widening the channel frequency.
- B. AP isolation is a security feature that prevents wireless clients on the same access point from communicating directly with each other; it has no effect on channel width or network speed.
- D. Burst mode is a proprietary or vendor-specific feature that allows temporary exceedance of normal data rate limits for short intervals; it is not related to configuring a specific 40 MHz channel width on an AP.
Concept tested. Channel bonding to achieve 40 MHz channel width
