Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 415

What are two functionalities of northbound and southbound APIs within Cisco SDN architecture? (Choose two.)

Answer options

• A. Northbound APIs utilize RESTful API methods such as GET, POST, and DELETE
• B. Southbound APIs utilize CLI, SNMP, and RESTCONF
• C. Southbound APIs are used to define how SDN controllers integrate with applications
• D. Northbound interfaces utilize OpenFlow and OpFlex to integrate with network devices
• E. Southbound interfaces utilize device configurations such as VLANs and IP addresses

Correct answer: A, B

Explanation

Option A is correct because northbound APIs indeed use RESTful methods like GET, POST, and DELETE to communicate with applications. Option B is also correct, as southbound APIs utilize protocols such as CLI, SNMP, and RESTCONF to interact with network devices. The other options are incorrect; C mischaracterizes the purpose of southbound APIs, D incorrectly states the functionalities of northbound interfaces, and E does not accurately describe the role of southbound interfaces.
