Question: What action can a Network Operator take with edge User Plane Functions (UPFs) in a 5G Core network during off-peak traffic hours to achieve energy savings, considering non-latency demanding traffic?
Option 1: Upgrade the edge UPFs to handle increased future demand.
Option 2: Redirect latency-demanding traffic to central UPFs while keeping edge UPFs active for all users.
Option 3: Maintain all edge UPFs in an active state to ensure constant network visibility.
Option 4: Redirect non-latency demanding traffic to central UPFs and decommission, scale down, or put out of service the edge UPFs.
Explanation: This action aligns with energy efficiency strategies by optimizing resource utilization based on demand. By redirecting non-latency sensitive traffic to central UPFs, the Network Operator can safely decommission or scale down edge UPFs during off-peak hours, reducing energy consumption without compromising service quality for users not requiring low latency services at that time.
