Answer options

• A. The southbound interface connects to routers and switches using IS-IS, OSPFv2, BGP-LS, and PCEP protocols
• B. The southbound interface is a RESTful implementation that can be programmed with a programming language
• C. The northbound interface connects to routers and switches using IS-IS, OSPFv2, BGP-LS, and PCEP protocols
• D. The northbound interface is a RESTful implementation that can be programmed with a programming language

Correct answer: A, D

Explanation

Option A is correct because the southbound interface indeed uses IS-IS, OSPFv2, BGP-LS, and PCEP protocols to connect with routers and switches. Option D is also correct as the northbound interface is a RESTful implementation that allows for programming. Options B and C are incorrect; B mischaracterizes the southbound interface and C incorrectly describes the northbound interface's connection methods.
