ABC Manufacturing has a heavily-used dual-band (2.4 / 5 GHz) WLAN, but sporadic RF interference across the 2.4 GHz band is causing dropped VoWiFi calls and leading to data connectivity and throughput problems.
In addition to avoiding 2.4 GHz channels and installing a distributed spectrum analyzer to locate RF interference sources, what should the implementer do to resolve the problem fully?

• A.Implement WPA-PSK everywhere in the network.
• B.Use captive portals for guest authentication in 5 GHz.
• C.Have only guest access on the 5 GHz channels.
• D.Move all corporate data clients and VoWiFi devices to the 5 GHz channels appropriate for their regulatory domain.

While using a USB adapter attached to a USB hub and your laptop for protocol analysts you notice that the SNR is lower than expected. The USB adapter is an 802 11 ac 3x3 3 adapter and is connected to a USB 3 hub.
What is likely causing the SNR variation?

• A.EMI from the battery in the device
• B.USB 3 0 interference
• C.USB 20 interference
• D.RF incidental energy generated by the cooling fans in the laptop

In what circumstance would you not enable DFS channels on a WLAN infrastructure?

• A.In an airport
• B.In any office complex
• C.In any stadium
• D.In any home office

What action should be taken after implementing a WLAN based on the design developed from the site survey process?

• A.Gathering facility documentation
• B.Design the infrastructure services
• C.Post-installation survey
• D.Requirements analysis

Which definition correctly describes the "local MAC" variation of the centralized WLAN architecture?

• A.The AP provides the RF termination point for the WLAN, but performs very few of the WLAN functions or services. The WLAN controller performs all MAC functions and the AP is very simple and lightweight.
• B.All RF-, data-, and control-related WLAN functions are performed by the AP. APs coordinate network services with one another and are managed by a WNMS,
• C.PHY functions are performed directly by the AP. MAC functions are divided almost equally between the WLAN controller and the AP, according to the time sensitivity of the feature or service.
• D.All MAC functions are performed by the AP. A minimal subset of network control is offloaded to the WLAN controller along with management and monitoring functions.
