Certified Information Systems Security Professional (CISSP) — Question 325

What are the three key benefits that application developers should derive from the northbound application programming interface (API) of software defined networking (SDN)?

Answer options

• A. Network syntax, abstraction of network flow, and abstraction of network protocols
• B. Network syntax, abstraction of network commands, and abstraction of network protocols
• C. Familiar syntax, abstraction of network topology, and definition of network protocols
• D. Familiar syntax, abstraction of network topology, and abstraction of network protocols

Correct answer: D

Explanation

The correct answer, D, highlights the importance of familiar syntax for developers, which simplifies integration, along with abstraction of network topology and protocols that allows for flexible network management. Options A and B include incorrect terms like 'network flow' and 'network commands' that do not align with the benefits of the northbound API. Option C incorrectly states 'definition of network protocols' instead of the correct abstraction.
