Question 1

What functionality does the control layer provide in a software-defined networking architecture?

    Correct Answer: B

    The control layer in a software-defined networking (SDN) architecture is responsible for establishing communication between the infrastructure layer (where the physical network devices reside) and the interface layer (which interacts with applications and users). It serves as the central intelligence and management point of the SDN, controlling the behavior and operation of the network.

Discussion
johnsonlddddOption: D

D. The middle layer of the SDN has two main tasks. One of them is to transfer and communicate with the application layer using the APIs and the next task is to receive the instructions from the networking devices present in the last layer. The controller receives the information from the hardware and sends it to the application layer after extracting the information. Here, when the information is received from the hardware, an abstract view is formed before it gets transferred to the application layer. This is the main task of the layer.

CA14Option: C

Control layer: It is responsible for making decisions such as how the packets should be forwarded based on the requirements Application layer: It communicates the requirements through the APIs to the control layer.

AynanalkadyOption: D

It also extracts the information about the network from the data plane and communicates it to the application layer.

d_g_talOption: B

the control layer is responsible for managing the communication between the infrastructure layer (where the physical network devices reside) and the interface layer (which interacts with applications and users).

MohamedFouadZOption: D

Consists of controllers and acts as a brain of the SDN architecture. It is responsible for making decisions such as how the packets should be forwarded based on the requirements, and relays the decisions to the networking devices (data plane) for execution

SherryVJOption: B

B. Establishes communication between the infrastructure and interface layers In a software-defined networking (SDN) architecture, the control layer is responsible for establishing communication between the infrastructure layer (data plane) and the interface layer (application layer). The control layer serves as the central intelligence and management point of the SDN, controlling the behavior and operation of the network.

Axterix2612Option: D

2: Consists of controllers and acts as a brain of the SDN architecture. It is responsible for making decisions such as how the packets should be forwarded based on the requirements, and relays the decisions to the networking devices (data plane) for execution. It also extracts the information about the network from the data plane and communicates it to the application layer. This layer forms the control plane.

AndreaszOption: D

D - making decisions. Data plane forwards packets

WazBlackOption: D

Control layer acts as a brain of the SDN architecture. It is responsible for making decisions such as how the packets should be forwarded based on the requirements, and relays the decisions to the networking devices (data plane) for execution. It also extracts the information about the network from the data plane and communicates it to the application layer.

Sk_44Option: D

answer is D

HhamdyOption: D

answer is D

vilokkumarOption: B

The control layer represents the centralized SDN controller software that acts as the brain of the software-defined network. This controller resides on a server and manages policies and traffic flows throughout the network.

Norbert_PueschelOption: D

Clearly this the only answer that makes sense. Data is moved by the infrastructure layer.
