Which statement describes the traffic throughput of the NSX Distributed Firewall?

By decoupling the firewall services from the virtualization layer, traffic is directed to the distribution layer for firewall processing within a service module. ✘ By deploying firewall software on a per virtual machine basis, firewall services will be distributed across multiple compute nodes. ✘ Firewall services are implemented as kernel modules and provide traffic filtering between the virtual machine's vNIC and the vSwitch. ✘ Firewall services are distributed as a software firewall appliance and may be deployed on more than one ESXi host for scalability and high availability. ✔

How does NSX simplify physical network design?

VLANs are moved into the virtual network for virtual machine traffic, eliminating the need to use PVLANs on the physical network. ✘ Network administrators only need to configure routing on the physical network for virtual machine traffic since all other network functions are moved to thevirtual network. ✘ Transport zones are created in the virtual network for virtual machine traffic, removing the need to make changes to the physical network. ✘ Virtual network integration can make changes to the physical network programmatically using REST API calls which automates network changes and increasesagility. ✔

How does NSX simplify the underlying physical network?

All configuration and state information is available via the REST APIs to automate the configuration of the physical network. ✘ All configuration and state information are readily accessible, as is the mapping between virtual network topologies and the physical network. ✘ All configuration and state information is stored in the local NSX BPDU database, eliminating the need for Spanning Tree Protocol (STP) on the physicalnetwork. ✘ All configuration and state information is cached by the NSX controllers, reducing the number of MAC/ARP table entries on the physical network. ✔
