What is a layer that is redundant for a Solution Architect to take into account when designing the Reusable Components for a project?
A . Logic layer
B . Persistence layer (saving data)
C . Process steps that are not part of the User Interlace interaction layer or the Logic layer or the Persistence layer
D . User interface interaction layer (interact with applications)

Answer: C

Explanation:

A reusable component is a workflow that can be compiled and packaged as an activity and reused in multiple processes. A reusable component should be designed with a clear purpose, input and output parameters, and error handling. A reusable component should also follow the best practices of modularity, reusability, maintainability, and scalability. A reusable component can be categorized into three layers: User Interface interaction layer, Logic layer, and Persistence layer. The User Interface interaction layer is responsible for interacting with applications, such as clicking, typing, or scraping data. The Logic layer is responsible for implementing the business logic, such as calculations, validations, or decision making. The Persistence layer is responsible for saving or retrieving data, such as using databases, files, or queues. These three layers are essential for designing reusable components, as they represent the common functionalities that can be shared across different processes. However, process steps that are not part of these three layers are redundant for a Solution Architect to take into account when designing the reusable components for a project. Process steps that are not part of these three layers are specific to a particular process or scenario, and they may not be applicable or compatible with other processes. For example, a process step that involves sending an email notification to a specific recipient or group may not be relevant or suitable for another process that uses the same reusable component. Therefore, such process steps should be avoided or separated from the reusable components, and instead be implemented in the main workflow of the process that requires them.
