After confirming that the slow network performance is due to non-essential traffic overloading the company's main data link during peak hours, what is the BEST next step to resolve this issue?
Throttle all non-essential traffic to reduce its bandwidth consumption
Implement Quality of Service (QoS) measures to prioritize essential operations
Expand the data link capacity to handle increased traffic volume
Establish a VPN for all external communications to improve security
Implementing Quality of Service (QoS) measures to prioritize essential operations over non-critical traffic ensures that crucial services receive the necessary bandwidth. This approach directly targets the congestion source and is typically more cost-effective and immediate than expanding link capacity, which may still leave critical traffic competing with bulk transfers. Blanket throttling of all non-essential services can unduly restrict legitimate usage, and establishing a VPN addresses security rather than bandwidth prioritization.
