What are the 3 layers that make up SDN Architecture?
1) Application layer, 2) Control layer, and 3) Infrastructure layer

1) Application layer, 2) Session layer, and 3) Presentation layer
Which of the following is NOT an advantage of SDN?
Network is programmable hence can easily be modified via the controller rather than individual switches
Switch hardware becomes cheaper since each switch only needs a data plane
The central dependency of the network means single point of failure, i.e. if the controller gets corrupted, the entire network will be affected.
Provides better security since the controller can monitor traffic and deploy security policies
In SDN, ________ consists of physical switches which forms the data plane and carries out actual movement of data packets
Session Layer
Infrastructure Layer
Control Layer
Application Layer
