Question: What is the correct format for constructing an SMF Set FQDN within an operator's PLMN?
Option 1: set<Set Id>.smfset.5gc.mnc<MNC>.mcc<MCC>.3gppnetwork.org
Option 2: smfset.set<Set Id>.5gc.mnc<MNC>.mcc<MCC>.3gppnetwork.org
Option 3: <MNC>.mcc<MCC>.smfset.set<Set Id>.5gc.3gppnetwork.org
Option 4: set<Set Id>.5gc.smfset.mnc<MNC>.mcc<MCC>.3gppnetwork.org
Explanation: According to the specification, an SMF Set FQDN within an operator's PLMN is constructed by adding the label "smfset" to the beginning of the Home Network Realm/Domain, resulting in the format set<Set Id>.smfset.5gc.mnc<MNC>.mcc<MCC>.3gppnetwork.org. This ensures a unique and standardized identifier for each SMF Set within an operator's network.
