Question: What is the primary method for estimating the energy consumption of a Virtualized Network Function (VNF) in terms of its constituent components?
Option 1: By measuring the total power supply to the physical servers hosting the VNF.
Option 2: Through direct measurement of each Virtualized Network Function Component's (VNFC) energy usage.
Option 3: By summing up the estimated energy consumption of its constituent Virtualized Network Function Components (VNFC).
Option 4: Based on the mean network traffic handled by the VNF.
Explanation: This is correct because, in the telecom domain's approach to virtualized network management, estimating a VNF's energy consumption involves breaking down the calculation to its constituent VNFCs. This method allows for more granular and accurate estimation of energy usage within virtualized environments, reflecting how resources are allocated and utilized in such setups.
