Explanation:

Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.

Some of the models used in the software development life cycle (SDLC) are;

I. A waterfall model.

II. An incremental model.

III. A spiral model.

Also, programming refers to a software development process which typically involves writing the sets of instructions (codes) that are responsible for the proper functioning of a software.

In this scenario, Brian is a computer engineer who writes security software for a banking system.

Thus, the pathway in the Information Technology career cluster that Brian's job falls into is Programming & Software Development.
