During a routine network check at an enterprise, the network administrator notices that network performance degrades every day between 3 PM and 5 PM. After some initial checks, they identify that the traffic during this period consistently exceeds the available bandwidth due to high video streaming usage. What is the most effective solution to mitigate this performance issue while maintaining essential services?
Change the work hours to distribute the load more evenly throughout the day.
Implement Quality of Service (QoS) to prioritize critical business applications.
Increase the overall bandwidth of the internet connection.
Completely restrict access to video streaming sites during peak hours.
