Question
Company XYZ needs to establish network connectivity to a newly acquired, adjacent building less than 1 kilometer (3280 feet) away. The project calls for implementing 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 established and the following message is observed in the logs: "DOT1X_SHIM-3-SUPP_START_FAIL: Unable to start supplicant on Dot11Radio1." What is most likely the root cause?
Options
- AThe non-root bridge is not configured for WPA key management.
- BThere is RF interference corrupting the 802.11b/g RF signal.
- CThe non-root bridge does not have the correct authentication credentials configured.
- DThe RADIUS service on the root bridge is not started or needs to be restarted.
