Question: Under what condition(s) will an eNodeB (eNB) NOT broadcast a received warning message when the Concurrent Warning Message Indicator IE is included, but the Repetition Period IE is set to '0'?
Option 1: Always, regardless of other IE settings
Option 2: Unless the Number of Broadcast Requested IE is specifically set to '1'
Option 3: If the Concurrent Warning Message Indicator IE's presence is accompanied by any value in the Number of Broadcast Requested IE other than '0'
Option 4: Never, it will always broadcast at least once
Explanation: When the Concurrent Warning Message Indicator IE is included but the Repetition Period IE is set to '0', the eNB will not broadcast the warning message except if the Number of Broadcast Requested IE is set to '1'. This highlights the importance of precise settings interactions in determining eNB behavior for broadcasting warnings.
