Online Access Free CWAP-405 Exam Questions

During an initial install of a controller-based WLAN, the APs are not locating the WLAN controller. The controller is two router hops away from the nearest AP. DHCP is not used. When performing a packet trace, you see a DNS response code of 3 targeted at one of the APs.
What is the problem?

• A.The controller host record has not been created in the DNS server
• B.The authentication to the DNS server failed
• C.The router is not forwarding packets to the DNS server
• D.The DNS server is not authoritative for the domain

You are concerned about attackers gaining access to your WLAN from outside the facility.
Why does reducing the output power on the APs not provide sufficient certainty that an attacker outside the facility cannot gain access?

• A.Because the attacker can simply use high gain antennas
• B.Because the attacker can increase the output power of the radio on the client
• C.Because the attacker will simplify use a lower gain antenna and a radio with higher receive sensitivity
• D.Because RF signals can be received even when weak if using a Mac OS X computer

You are using a Wireless Aggregator utility to combine multiple packet captures. One capture exists for each of channels 1, 6 and 11.
What kind of troubleshooting are you likely performing with such a tool?

• A.Fast secure roaming problems.
• B.Narrowband DoS attack detection.
• C.Interference source location.
• D.Wireless adapter failure analysis.

Which one of the following is not a valid acknowledgement frame?

• A.CTS
• B.Ack
• C.Block Ack
• D.RTS

You need to determine RF activity over time in a spectrum analyzer. It is to be able to see the activity and the amplitude of that activity.
What kind of view should be used?

• A.Channel listing
• B.Swept spectrogram
• C.Real-time FFT
• D.Device listing
