What is true of Software Defined Network firewalls?
Software Defined Network (SDN) firewalls are characterized by their flexibility and are not limited based on physical topology. Unlike traditional hardware firewalls that depend on the physical network layout, SDN firewalls operate based on the software-defined network policies, making them more adaptable to dynamic networking environments.
they aren’t limited based on physical topology
E. They are not limited based on physical topology
Option A SDN firewalls (e.g., security groups) can apply to assets based on more flexible criteria than hardware-based firewalls, since they aren’t limited based on physical topology. (Note that this is true of many types of software firewalls, but is distinct from hardware firewalls). SDN firewalls are typically policy sets that define ingress and egress rules that can apply to single assets or groups of assets, regardless of network location (within a given virtual network). For example, you can create a set of firewall rules that apply to any asset with a particular tag. Keep in mind this gets slightly difficult to discuss, since different platforms use different terminology and have different capabilities to support this kind of capability, so we are trying to keep things at a conceptual level.
I don't with A, since it's clearly saying SG Page#81 "SDN firewalls (e.g., security groups) can apply to assets based on more flexible criteria than hardware-based firewalls, since they aren’t limited based on physical topology." Correct answer is E
