CWNP CWSP-207 Exam - Topic 2 Question 39 Discussion

Given: In XYZ's small business, two autonomous 802.11ac APs and 12 client devices are in use with WPA2-Personal.What statement about the WLAN security of this company is true?
B) A successful attack against all unicast traffic on the network would require a weak passphrase dictionary attack and the capture of the latest 4-Way Handshake for each client.
A) Intruders may obtain the passphrase with an offline dictionary attack and gain network access, but will be unable to decrypt the data traffic of other users.
C) An unauthorized wireless client device cannot associate, but can eavesdrop on some data because WPA2-Personal does not encrypt multicast or broadcast traffic.
D) An unauthorized WLAN user with a protocol analyzer can decode data frames of authorized users if he captures the BSSID, client MAC address, and a user's 4-Way Handshake.
E) Because WPA2-Personal uses Open System authentication followed by a 4-Way Handshake, hijacking attacks are easily performed.

Wait, can unauthorized users really eavesdrop? Sounds sketchy.

I’m a bit confused about option D. I thought capturing the BSSID and MAC address was important, but does that really allow decoding of all data frames?

I feel like option C might be correct since I recall that WPA2-Personal doesn't encrypt multicast or broadcast traffic, allowing some eavesdropping.

I think option B sounds familiar from practice questions. It mentioned needing the 4-Way Handshake, which is crucial for attacks on unicast traffic.

I remember studying that WPA2-Personal can be vulnerable to dictionary attacks, but I'm not sure if that means intruders can decrypt all traffic.
