You are developing a distributed software system. Which of the following is least likely a constituent system element? (Wentz QOTD)
A. Application programming interface (API)
B. Software development kit (SDK)
C. Interface description language (IDL)
D. Dependent processes using static libraries

Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is B. Software development kit (SDK).

Wentz’s book, The Effective CISSP: Security and Risk Management, helps CISSP and CISM aspirants build a solid conceptual security model. It is a tutorial for information security and a supplement to the official study guides for the CISSP and CISM exams and an informative reference for security professionals.

A software development kit (SDK) is a collection of software development tools in one installable package. They facilitate the creation of applications by having a compiler, debugger and perhaps a software framework. They are normally specific to a hardware platform and operating system combination. To create applications with advanced functionalities such as advertisements, push notifications, etc; most application software developers use specific software development kits.

Elements of a distributed software system typically communicate through defined application programming interfaces (API).

An SDK is a collection of software development tools. It’s not a constituent system element.

Dependent processes are part of the distributed software system. It doesn’t matter if they use static or dynamic libraries.

An interface description language (IDL) is used to define interfaces that are then translated into specific programming languages.
