Question 136
After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor performance in the 2.4 GHz band. Primarily, you've designed the WLAN for 5 GHz and 2.4 GHz as a best effort. You found out that the implementers didn't follow your guidelines when configuring the WLAN infrastructure. What can you do to minimize as much as possible the CCI impact in the 2.4 GHz band?
Question 137
During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is intermittent.
Every other time of the day, it works fine.
What's the likely cause of this issue?

Question 138
What are the two most common industry-standard protocols used to transport data from an AP to a Wireless LAN Controller?
Question 139
In a manufacturing facility with highly reflective materials, you are planning an upgrade to your existing
802.11b WLAN implementation. You have chosen a dual-band 802.11n infrastructure product for this purpose. Your client applications include:
Handheld scanners for inventory management
Toughbooks (laptops) mounted on forklifts for inventory and workflow management VoWiFi phones used by select employees throughout the facility You are evaluating all of the 802.11n enhancements and determining which features to enable for your environment and applications.
In this scenario, what 802.11n enhancement typically should NOT be enabled on the 2.4 GHz radio of the new APs?
