With software-defined networking (SDN), which two types of network operations are segregated to allow for granularity and delegation of administrative access and functions? 

Answer options:

A. Filtering and forwarding
B. Filtering and firewalling
C. Firewalling and forwarding
D. Forwarding and protocol

A

With SDN, the filtering and forwarding capabilities and administration are separated. This allows the cloud provider to build interfaces and management tools for administrative delegation of filtering configuration, without having to allow direct access to underlying network equipment. Firewalling and protocols are both terms related to networks, but they are not components SDN is concerned with.
