   A service provider is deploying a VNF that must be scaled out during peak hours and scaled in during off-peak hours. The provider wants to automate this process based on CPU utilization. Which approach is the most appropriate?

   • AManually scale the VNF by creating new instances during peak hours.
   • BConfigure the VNF Manager to monitor CPU utilization and trigger scaling operations based on predefined thresholds.
   • CUse the VIM to automatically scale the VNF based on CPU utilization.
   • DUse the NFV Orchestrator to define scaling policies that instruct the VNF Manager to scale based on CPU utilization.

   A network operator is comparing a virtual router (VNF) with a traditional hardware router for a new customer edge deployment. The operator's primary concern is the ability to quickly scale capacity during peak hours. Which advantage of the VNF best addresses this concern?

   • AThe VNF provides higher throughput than the hardware router because it uses the CPU more efficiently.
   • BThe VNF can be cloned and instantiated on additional compute resources within minutes, providing rapid scale-out.
   • CThe VNF has a lower per-packet latency than the hardware router because it runs in software.
   • DThe VNF does not require any management or orchestration, simplifying operations.
