The controller has a global view of the network, and it can easily ensure that the network is in a consistent and optimal configuration. Which two statements describe a centralized SDN control path? (Choose two.)

• A.Scaling of the centralized controller cluster is challenging for services like DHCP and load-balancing.
• B.It is highly-available by design with no single-point-of-failure risks present.
• C.Integrating smart NIC capabilities on the local host level is made easier through REST APIs.
• D.It significantly improves the latency when performing reactive handling of PACKET_IN events.
• E.The centralized controller can support all southbound APIs, which allows for easy integration with legacy equipment.
