CWNA-107 Exam Dumps - Certified Wireless Network Administrator
You recently purchased four laptops containing dual-band 802.11ac adapters. The laptops can connect to your 2.4 GHz network, but they cannot connect to the 5 GHz network. The laptops do not show the 5 GHz SSIDs, which are different than the 2.4 GHz SSIDs. Existing devices can connect to the 5 GHz SSIDs with no difficulty. What is the likely problem?
You are troubleshooting a WLAN problem and you suspect hidden node as the cause. What should you look for in a protocol analyzer?
What 802.11 network configuration would result in multiple stations broadcasting Beacon frames with the same BSSID but with different source addresses?
What standard is referenced in the 802.11-2016 specification and is recommended for robust WLAN client security?
A WLAN is implemented using wireless controllers. The APs must locate the controllers when powered on and connected to the network. Which one of the following methods is commonly used to locate the controllers by the APs?
Three access points are used within a facility. One access point is on channel 11 and the other two are on channel 1. The two access points using channel 1 are on either side of the access point using channel 11 and sufficiently apart so that they do not interfere each other when they transmit frames. Assuming no other Aps are in the vicinity, is CCI still a possibility in this network and why?
The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The user indicate that they need more throughput and all stations are 5 GHz capable 802.11ac clients. The current AP configuration uses 20 MHz channels in both 2.4 GHz and 5 GHz. What is the least expensive solution available for increasing throughput for these users without implementing configuration options that are not recommended?
You are configuring an access point to use channel 128. What important fact should be considered about this channels?
You are attempting to explain RF shadow and how it can cause lack of coverage. What common building item frequently causes RF shadow and must be accounted for in coverage plans?
What ID is typically mapped to an AP’s MAC address if a single BSS is implemented?
Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?
A natural disaster has occurred in a remote area that is approximately 40 miles from the response team headquarters. The response team must setup a local wireless network using 802.11 WLAN access points. What is the best method, of those listed, for implementation of network backhaul for communications across the Internet in this scenario?
You administer a WLAN that offers a guest SSID of GUESTNWORK. Users connect to the GUESTNWORK SSID, but report that they cannot browse the Internet. The devices simply report no Internet connection. What common problem causes this scenario?
What wireless networking term describes the increase of RF energy in an intentional direction with the use of an antenna?
An RF sigma sometimes bends as it passes through some material other than free space. What is the term that describes this behavior?
A dual-band 802.11ac AP must be powered by PoE. As a class 4 device, what power level should be received at the AP?
