• A. 450 Mbps throughput is the client max for 5-GHz radio.
• B. Channel bonding on 5 GHz is required for a client to have a 300 Mbps WiFi link.
• C. 300 Mbps throughput is the client max for 2.4-GHz radio.
• D. The remaining bandwidth is divided per device when more clients are connected to one AP.
• E. 100 Mbps Ethernet switch port is a potential bottleneck.
• F. CleanAir helps clear noise for 802.11n channel bonding to work.

Answer: ACE

NEW QUESTION 7
Which option is an advantage at using Cisco CleanAir technology in your wireless network?

• A. CleanAir can be used on an AP in monitor mode so that the AP serves client traffic and monitors for interference simultaneously.
• B. A single CleanAir AP can be used to analyze RF traffic from many APs
• C. CleanAir is a software feature that can be added to arty AP to start monitoring interference and air quality.
• D. CleanAir operates 24/7 and constantly monitors for interference and air quality issues.

Answer: D

Explanation: An advantage of CleanAir technology is that it operates 24/7, constantly monitoring for interference and air quality issues (see Figure 2). This allows IT to take a more proactive approach to spectrum management.
Instead of waiting for interference to be reported by an end user (in the form of a trouble ticket) and then dispatching a tool to analyze the problem, IT can find interference as soon as it occurs and take immediate action. Having a 24/7 history also makes it possible to look back in time. Using historical data, it's easy to perform analyses of trends over time.
