Question: Which of the following types of network functions are the requirements for Power Energy Efficiency (PEE) measurement control, data file reporting and streaming, fault supervision, and configuration management specifically applicable to?
Option 1: All 4G and 5G logical network functions
Option 2: 5GS physical network functions
Option 3: Both 4G and 5G virtual network functions
Option 4: Only 4G physical network functions
Explanation: This is correct because the specified requirements (PEE measurement control, data file reporting and streaming, fault supervision, and configuration management) are explicitly stated to be valid only for 5GS (Fifth Generation Core Network) physical network functions, highlighting a focus on the energy efficiency aspects unique to the physical infrastructure of 5G networks.
