Question: What action should the User Equipment (UE) take upon receiving an RRC Release message from the eNodeB?
Option 1: Perform the actions as specified for connection release.
Option 2: Ignore the message and continue with the existing configuration.
Option 3: Send a request to re-establish the connection.
Option 4: Enter a dormant state until further instructions are received.
Explanation: Upon receiving an RRC Release message, the UE should perform the actions as specified for connection release. This is because the RRC Release message indicates that the eNodeB is releasing the connection with the UE, and the UE needs to take necessary steps to release resources and enter a state where it can re-establish the connection if needed.
