The following are some wireless networking interview questions
Interview question 1
Which protocol does WEP use for encrypting data.
WEP uses RC4 for encryption.
Interview question 2
Name two protocols which are used by wireless clients in a 802.1x authentication
EAP-TLS and PEAP-MSCHAP v2.
Interview question 3
Is 802.11 wireless communication full or half duplex
802.11 uses half duplex communication.
Interview question 4
Name two radius servers which can be used for setting up a secure wireless network.
IAS and Freeradius
Interview question 5
At which layer does WPA encrypt data
It encrypts data at the data link layer.
Interview question 6
If three wireless stations communicate with an access point which supports 54 Mbps, what would be the theoretical bandwidth for each user.
802.11 is a shared medium. All users share the bandwidth. So it would be 54/3 per station.
Interview question 7
Why is mac-filtering an insecure form of authentication in a wireless network.
A wireless network uses a shared medium, which makes it possible for any user on the wireless network to sniff for valid mac-addresses on the network.
Interview question 8
Which protocol does PEAP use to derive session encryption keys.
It uses TLS.
Interview question 9
At which layer of the OSI model does WPA handshake work on
