Question: In the context of Telecommunication Management (PS Domain), what protocol is mandated for the network IP layer beneath the Path Protocol, as per STD compliance?
Option 1: Transmission Control Protocol (TCP)
Option 2: Internet Protocol (IP) compliant with STD 0005
Option 3: User Datagram Protocol (UDP)
Option 4: Hypertext Transfer Protocol (HTTP)
Explanation: The correct answer is IP compliant with STD 0005, as specified in the network layer requirements. This ensures interoperability and standardization across different network implementations. IP is a fundamental protocol for routing data packets between networks, making it the appropriate choice beneath the Path Protocol for managing PS domain charging data.
