According to page no: 348 WPA/WPA2-Preshared Keys is crackable means TKIP and CCMP passphrase can be compromised. If real exam ask the question related to this?..what should I select (different practice test have different answers)?.Kindly advice me.

Please advice me.

Someone swiped my CWSP book, so I can't read the original text you are referencing, but

WPA when used with WMM is showing weaknesses, but is not yet broken.

WPA2 with CCMP - not yet, nor probably for a long time to come.

All IMHO.

But page no: 348 says same......WPA/WPA2-PSK is particularly susceptible to dictionary attacks against weak passphrases.

There are some article on net regarding WPA2 cracking.

Also found this, but is it an article or an advertisement?:

WPA/WPA2 passphrases are definitely crackable if they are not sufficiently long and complex. If you capture the 4-way handshake, you can run it against a dictionary file and recover the passphrase.

What is sufficiently long and complex? Most researchers recommend 20+ mixed characters.

OOPS,

Too tired last night. Forgot about capturing the WPA handshake. My bad.
