Question: For a test case specifically applying to Terminals accessing the Narrowband Internet of Things (NB-IoT) network, which 3GPP Technical Specification provides the basis for all performed procedures during the test?
Option 1: TS 34.108 (UTRAN)
Option 2: TS 51.010-1 (GERAN)
Option 3: TS 36.508
Option 4: TS 38.508-1 (5G-NR)
Explanation: This is because, for Terminals accessing NB-IoT, the procedures in TS 36.508 serve as the basis for all performed test procedures, detailing default behavior for NB-IoT.
