What are two functionalities of SDN Northbound APIs? (Choose two.)
What are two functionalities of SDN Northbound APIs? (Choose two.)
Northbound APIs form the interface between the SDN controller and business applications, allowing these applications to communicate their requirements and obtain resources from the network. Additionally, Northbound APIs provide a programmable interface for applications to dynamically configure the network, enabling greater flexibility and automation. These functions are critical for the operational efficiency and adaptability of Software-Defined Networking (SDN).
B and C. E can't be correct as NETCONF is a southbound API
It must be BC Netconf is southbound and Openflow too
I will go with B and C OpenFlow and NetConf I think are southbound protocols,
B&C only
B & C....
BC other answers incorrect
What is the function of a northbound API? Northbound APIs are the link between the applications and the SDN controller. The applications can tell the network what they need (data, storage, bandwidth, and so on) and the network can deliver those resources, or communicate what it has.
NETCONF is southbound not northbound
this must be bc
C tricked me. If it was "Northbound APIs provide a programmable interface for applications" it would have been less tricky.
"NETCONF (RFC 6241) is an XML-based protocol that client applications use to request information from AND make configuration changes to the device." from: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/168/b_168_programmability_cg/NETCONG_YANG.pdf
I agree, must be B and C imo
