The major component of network virtualization architecture that isolates users according to policy is policy enforcement, which is option A.
Policy enforcement involves implementing policies across the network to ensure that traffic is only allowed to flow between authorized sources and destinations. This is achieved by defining and enforcing access control policies, which dictate what traffic is allowed to pass through the network.
Access control is another component of the network virtualization architecture, which controls and manages access to network resources based on policies. Access control is typically implemented through the use of firewalls, intrusion detection and prevention systems, and other security technologies.
Network services virtualization is the process of abstracting and virtualizing network services, such as routing, switching, and firewalls, so that they can be easily deployed and managed in a virtualized environment.
Path isolation is a technique used in network virtualization to ensure that traffic flows only along authorized paths in the network. This is achieved by creating virtual network segments or tunnels that isolate traffic from different parts of the network.
In summary, policy enforcement is the major component of the network virtualization architecture that isolates users according to policy by implementing access control policies to regulate traffic flow across the network.
