Question: In a typical E-UTRA and EPC conformance testing setup for User Equipment (UE), what is the expected state of the UE before commencing tests?
Option 1: The UE is in state Registered, Idle Mode
Option 2: The UE is in state Deregistered, Connected Mode
Option 3: The UE is in state Registered, Connected Mode
Option 4: The UE is in Power Off State
Explanation: Starting from a known, stable state is crucial for E-UTRA and EPC conformance testing. Being 'Registered' ensures the UE has completed authentication and attachment procedures with the network. The 'Idle Mode' signifies no active connection, providing a baseline state for initiating test scenarios without pre-existing session influences, allowing evaluation of the UE's behavior from a well-defined starting point.
