B.

Explanation:
Enabling EAP on the Access Point
Follow these steps to enable EAP on the Access Point:
1. Follow the link path to the Authentication Server Setup page.
2. Enter the name or IP address of the RADIUS server in the Server Name/IP entry field.
3. Enter the port number your RADIUS server uses for authentication. The default setting, 1812, is the port setting
for many RAFIUS servers;
1645 is the port setting for Cisco’s RADIUS server, the Cisco Secure Access Control Server (ACS).
Check your server’s product documentation to find the correct port setting.
4. Enter the shared secret used by your RADIUS server in the Shared Secret entry field. The shared secret on the
Access Point must match the shared secret on the
RADIUS server.
5. Enter the number of seconds the Access Point should wait before authentication fails.
6. Click OK. Returns to the Security Setup page.
7. On the Security Setup page, click Radio Data
Encryption (WEP) to browse to the AP Radio Data
Encryption
page.
8. Select Network-EAP for the Authentication Type
setting. You can also enter this setting on the AP Radio
Advanced page.
9. Check that at least one WEP key has been assigned a key size and has been selected as the transmit key. If a WEP
key has been set up, skip to Step 13. If no WEP key has been set up, proceed to Step 10.
10. Enter a WEP key in one of the Encryption Key
fields. The Access Point uses this key for multicast data signals
(signals sent from the Access Point to several client devices at once). This key does not need to be set on client
devices.
11. Select 128-bit encryption from the Key Size
pull-down menu.
12. Select the key as the transmit key.
13. Click OK. Return automatically to the Security Setup page.
