Company XYZ needs to establish network connectivity to a newly acquired, adjacent building less than 1 kilometer (3280 feet) away. The project calls forimplementing a wireless solution using autonomous access points in a point-to-point bridging solution using external antennas on interface dot11radio1.You need to secure the bridge link with strong EAP, DOT1x, and WPA methods, using a local RADIUS server. However, the link cannot be establishedand the following message is observed in the logs: “DOT1X_SHIM-3-SUPP_START_FAIL: Unable to start supplicant on Dot11Radio1.” What is mostlikely the root cause?
A. The non-root bridge is not configured for WPA key management.
B. There is RF interference corrupting the 802.11b/g RF signal.
C. The non-root bridge does not have the correct authentication credentials configured.
D. The RADIUS service on the root bridge is not started or needs to be restarted.
