Question: When a UE capable of simultaneously connecting to an SNPN and a PLMN is not set to operate in SNPN access mode, what procedure does it perform using the corresponding interface for connection to the PLMN?
Option 1: The UE performs SNPN selection procedures.
Option 2: The UE only performs PLMN selection procedures.
Option 3: The UE performs both SNPN and PLMN selection procedures simultaneously.
Option 4: The UE does not perform any network selection procedure.
Explanation: According to the 3GPP specification, when a UE capable of simultaneously connecting to an SNPN and a PLMN is not set to operate in SNPN access mode for any of the Uu/Yt/NWu interfaces, it only performs PLMN selection procedures using the corresponding interface for connection to the PLMN.
