Question: In RF testing for User Equipment (UE) as per 3GPP specifications, from which of the following UE States can the RB (Radio Bearer) Test Mode State NOT be directly reached, according to the defined test environments?
Option 1: UE State 2
Option 2: UE State 5
Option 3: UE State 6
Option 4: UE State 7
Explanation: The RB Test Mode State can be directly reached from UE States 2, and 7. Since UE State 6 is not among these, it stands out as the correct answer because it was not listed as one of the states from which the RB Test Mode State can be directly reached.
