Question: What does the 'failureWlanRadioLink' value of the WLAN-Status Information Element (IE) in a Radio Resource Control (RRC) protocol typically indicate about a User Equipment's (UE) WLAN connection?
Option 1: The UE has successfully associated with a WLAN network.
Option 2: A radio link failure occurred during the UE's attempt to connect to a WLAN.
Option 3: The UE's WLAN connection is currently suspended due to inactivity.
Option 4: The WLAN network is unavailable due to external factors (e.g., maintenance, out of range).
Explanation: The 'failureWlanRadioLink' value specifically points to an issue at the radio link layer during the connection attempt. This suggests a problem with the wireless communication link between the UE and the WLAN access point, rather than higher-layer association issues, suspension due to inactivity, or the network being unavailable for other reasons.
