NO.10 You have just installed two ProCurve 5406zl switches, one on the second floor and one on the third
floor of your office. You are using 802.1X for port-access authentication. All users have an 802.1X
supplicant installed on their computers and you have configured a RADIUS server with a remote access
policy for each floor. Shortly after connecting the computers, users on the second floor report that they
cannot access any network resources. You can ping the RADIUS server from both switches, but when
you check the RADIUS log, you see authentication requests coming only from the third floor switch. Why
are the second floor users unable to connect to the network?
A. The IP address of the RADIUS server has not been configured on the second floor switch.
B. The second floor computers are using the wrong EAP type for authentication with the RADIUS server.
C. The shared secret configured on the second floor switch does not match the shared secret configured
on the RADIUS server.
D. No default gateway has been configured on the second floor switch, therefore no authentication
requests can reach the RADIUS server.
