Question: In a single cell environment for UE conformance testing, as per default initial conditions, what is the expected state of the User Equipment (UE) in relation to both HRPD and E-UTRAN?
Option 1: HRPD Active Mode, E-UTRAN Deregistered State
Option 2: HRPD Registered, Dormant Mode, pre-registered on E-UTRAN State (State H2A)
Option 3: HRPD Registered, Active Mode, E-UTRAN Registered State
Option 4: HRPD Deregistered, E-UTRAN Registered, Connected State
Explanation: This correct answer reflects the specified initial conditions for UE conformance testing in a single cell environment. Being in 'HRPD Registered, Dormant Mode' indicates the UE is registered with the High Rate Packet Data (HRPD) network but is currently not actively transferring data, conserving resources. Meanwhile, being 'pre-registered on E-UTRAN state (State H2A)' signifies the UE's readiness to quickly transition to active use on the Evolved UTRA Network (E-UTRAN) when needed, aligning with efficient network attachment protocols for seamless user experience in telecom networks.
