Question No. 2

Which one of the best following is an advantage of using display filters instead of capture-time filters?

ADisplay filters allow for focused analysis on just the packets of interest

BOnce created display filters are reusable for later captures

CDisplay filters only hide the packets from view and the filtered packets can be enabled for view later

DMultiple display filters can be applied simultaneously

Show Answer

Correct Answer: A

display filters allow you to focus on things of interest and to ignore things you don't care about.

Question No. 3

Using a portable analyzer you perform a packet capture next to a client STA and you can see that the STA is associated to a BSS. You observe the STA sending packets to the AP and the AP sending packets to the ST

ALess the 2% of all packets are retransmissions. You move to capture packets by the AP and, while the retry rate is still very low, you now only see unidirectional traffic from the AP to the client. How do you explain this behavior?

AThere is a transmit power mismatch between the client and the AP and while the client can hear the Aps traffic, the AP cannot hear the client.

BThe portable analyzer has a lower receive sensitivity than the AP and while it can't capture the packets
from the client STA, the AP can receive them OK.

CThe STA is transmitting data using more spatial streams than the potable analyzer can support

DThe portable analyzer is too close to the AP causing CCI, blinding the AP to the client's packets

Correct Answer: B

Question No. 4

C4-Way Handshake

DProbe Response
