Question 17

An architect designs a multi-controller network architecture with these requirements:

* Achieve fast failover to control traffic when controllers fail.

* Yield a short distance and high resiliency in the connection between the switches and the controller.

* Reduce connectivity loss and enable smart recovery to improve the SDN survivability.

* Improve connectivity by adding path diversity and capacity awareness for controllers.

Which control plane component of the multi-controller must be built to meet the requirements?

    Correct Answer: B

    To achieve fast failover, short distance, high resiliency, path diversity, and capacity awareness in a multi-controller network architecture, building control path reliability is crucial. This ensures that even if some controllers fail, the remaining controllers can manage the network effectively by leveraging diverse and redundant paths. Control path reliability optimizes the connection between switches and controllers, ensuring that the network can recover swiftly and maintain connectivity, thereby enhancing SDN survivability.

i agree that SURVIVOR meets most of the given keywords and hints. Answer B seems correct to me too

exmjameOption: C

C. Look at the "FIGURE 7. The multi-controller consistency solutions" in this ieee reference doco - https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=8314783

gohorOption: C

C should be the correct answer

Redrum702Option: B

My revised answer is B: disregard my previous answer of D.

Redrum702Option: D

Answer is D: Controller Clustering - involves grouping multiple SDN controllers to work together as a single logical unit. This approach enhances the reliability, scalability, and fault tolerance of the network control plane.

walkwolf3Option: B

The answer is between controller path and node, controller path reliability is a better option.
