Answer options:

A.…to present the minimally tailored standard solution that reflects the requirements, you need to prepare a Prototype demo
B.…to illustrate the implementation of the particular requirements, you need to prepare a Prebuilt demo.
C.…to present the current functionality of the standard solution, you need to prepare an Out-of-the-box demo
D.…to customize a standard solution for a particular vertical, you need to prepare a Proof of concept demo

Correct Answers: A and C 
Visual presentation of the requirements is a vital communication step between a Solution Architect and a customer. There are several types of demos that you can use along with your story presentation to the stakeholders: Out-of-the-box — this demo presents the capabilities of the out-of-the-box solution without any customizations. It provides information to the stakeholders about the system`s current functionality. The out-of-the-box demo does not illustrate the requirements but only familiarizes customers with the core features.
Prebuilt — this demo is tailored to the particular vertical and provides more specific to the stakeholders` business information than an out-of-the-box demo.
Prototype — this demo presents the minimally tailored out-of-the-box solution that reflects the customer`s needs or requirements.
Proof of concept — this demo focuses on illustrating the implementation of the particular requirements, components, or technical solutions.
Option B is incorrect because an illustration of the implementation of the particular requirements is a Proof of concept demo but not a Prebuilt demo.
Option D is incorrect because customization of a standard solution for a particular vertical is a Prebuilt demo but not a Proof of concept demo.
