Exam 200-301 topic 1 question 767 discussion

In a controller-based network, `off-the-shelf` switches primarily function to **forward packets**. They are controlled by an SDN controller, which takes the computational complexity away from the SDN network devices. This makes the switches more "commoditized", which is a synonym for lower costs. Therefore, the correct answer is **B. forwarding packets**.

B is correct

A. Forwarding packets

Look at question 789, it makes it clear. Both A and D are controller based. A. setting packet-handling policies D. making routing decisions

packet-handling policies is another name for QOS and it's done by the control plane, not the data plane. The control plane performs forwarding decisions and other functions, like quality of service (QoS). https://www.splunk.com/en_us/blog/learn/control-plane-vs-data-plane.html#:~:text=The%20control%20plane%20performs%20forwarding,inputs%20from%20the%20control%20plane. https://marco.uminho.pt/disciplinas/ST/st0304/packethandling.pdf

In SDN's purest form, the controller has all the intelligence: Switches are dumb, commercial off- the-shelf (COTS) devices that are managed by the controllers. Therefore we can deduce "off-the-shelf" switches are only used to forward packets. https://quizlet.com/761289670/6-automation-virtualization-cloud-sdn-dna_14548715_2023_01_05_20_24-flash-cards/

The answer is B, A is wrong as. The controller is responsible for setting packet-handling policies, making routing decisions, and providing a central view of the deployed network.

A Control Plane: All activities that are necessary to perform data plane activities but do not involve end-user data packets Making routing tables Setting packet handling policies (e.g., security) Base station beacons announcing availability of services

just trying to confuse you with controller based network. Doesn't matter

Correct answer is A

Shouldn't the correct answer be D. Please let me know if it's wrong.

Newbie here, got answer A from other dumps, can anyone clarify? Please and thank you.
