Question: In an Isolated Operation for Public Safety (IOPS) mode, what is the primary role of an IOPS MC Connectivity Function supporting IP connectivity functionality for Mission Critical (MC) services?
Option 1: To provide MC services directly to User Equipment (UEs)
Option 2: To discover MC service users and facilitate IP connectivity among them via unicast and/or multicast transmissions
Option 3: To manage the prioritization of MC services over non-MC traffic in the IOPS network
Option 4: To handle the authentication of MC service UEs before allowing access to the IOPS network
Explanation: The correct answer is actually Option 2 because, according to the specifications for IOPS mode operation, an IOPS MC Connectivity Function that supports IP connectivity functionality does not directly provide Mission Critical services. Instead, its primary role is to enable the discovery of MC service users and to provide IP connectivity for communication among these discovered users by distributing related IP traffic over IP unicast and/or multicast transmissions.
