A company is looking to modernize its networking infrastructure to improve management efficiency and better control network traffic flows. Which type of network architecture should they implement to allow central control of network traffic without requiring physical access to the network switches?
Managed switches offer wide configuration options but do not centralize control to the extent of abstracting control functions from hardware devices.
A network interface card manages connections for an individual device but does not control network traffic flow across the entire network.
A virtual LAN can help segment the network traffic but does not by itself offer centralized control of the entire network infrastructure.
Software-defined networking would provide central control and dynamic traffic management capabilities.
