  1. Answer B is correct. Wireless clients typically use Diffie-Hellman Group 7 for small processor devices such as wireless devices. Answers A, C, and D are incorrect because these groups would not typically be found on wireless or other small processor devices.

  2. Not sure where DH 7 comes from ?

    IPSec IKE uses Diffie-Hellman groups to block easily-decrypted keys. Enter these commands to configure the Diffie-Hellman group on a wireless LAN with IPSec enabled:

    •config wlan security ipsec ike DH-Group wlan-id group-id

    –For group-id, enter group-1, group-2 (this is the default setting), or group-5.

    •Enter show wlan to verify that IPSec IKE DH group is configured.
