企業は、論理トポロジやデバイスの動作および管理方法を変更することなく、内部物理ネットワークのレプリカを仮想化する必要があります。この要件を満たすテクノロジーは次のうちどれですか?
正解:A
NFV allows network functions, such as firewalls, routers, and load balancers, to be virtualized and run on industry-standard servers instead of having dedicated hardware appliances. This approach enables network services to be rapidly deployed, scaled, and managed in a more flexible and cost-effective manner. By using NFV, the company can create a virtual replica of its physical network, with the same logical topology and behavior, while running network functions as virtualized instances.
