최신 CWAP Certification CWAP-402 무료샘플문제:
1. When evaluating modulation and coding schemes, you must determine the best coding rate available. In 802.11 MCS tables, what is the best coding rate from the perspective of highest data rates?
A) 5/6
B) 1/2
C) 2/3
D) 3/4
2. You have captured 802.11 traffic using an adapter that includes the radio tap header. You see several frames often called announcement frames in the capture.
What best describes these types of frames?
A) They only include beacon and probe response frames
B) They are used to allow a STA to awake from sleep and for no other reason
C) They only include beacon and probe request frames
D) They are meant to provide information to the network that may result in state changes, but they are not open for rejection
3. You are using the real-time FFT display of a spectrum analyzer.
In what domain does this show the RF energy detected in the swept frequencies?
A) Frequency
B) Time
C) Length
D) Phase
4. While troubleshooting DHCP issues, you perform a protocol capture in order to determine if the DNCP pool is depleted. The capture does not show DHCPnak messages.
Where else could you look to determine if the pool is depleted?
A) Spectrum analyzer
B) Switch logs
C) DHCP server logs
D) AP logs
5. You are considering disabling the data rates of 1, 2, 5.5 and 11 in the 2.4 GHz band.
What advantage might this provide to the networks operating in this band?
A) The range of the PHY preamble and header will be reduced
B) Frames that must be transmitted at the lowest common data rate can be transmitted at higher data rates after the change
C) The antennas will be able to zero in on the higher data rates better
D) The RF signals will not travel as far
