You need to build a new PCF grid component with the name “NewPCFComponent” for a model-driven app. 
You create a directory for your project and define the namespace “PCFSpace” for the component. 
What will be your next two steps to create a PCF component?

Answer options:

A.npm run build
B.pac pcf new --namespace PCFSpace --name NewPCFComponent --template dataset
C.pac pcf init --namespace PCFSpace --name NewPCFComponent --template field
D.npm install
E.pac pcf init --namespace PCFSpace --name NewPCFComponent --template dataset
F.npm start
G.pac pcf new --namespace PCFSpace --name NewPCFComponent --template field

Correct Answers: D and E 
The Components are reusable blocks that you can use for Power Apps applications. Power Apps provides out-of-the-box standard controls (components) for creating applications, like HTML Text, Vertical Gallery, or Edit Form. If your Power Platform solution requires more than standard controls, Power Apps also provides tools to create and reuse the custom components. Power Apps Component Framework (PCF) helps you to create these components. You can import and export components from other applications or store them in the Components Library. 
To create a PCF component, Microsoft provides three simple steps: Create a project directory
Create a new component from the template in a project directory
Install all dependencies required for your component
First, you create a directory for your component project. You can use the mkdir command, like 
 mkdir NewPCFComponent. 
The second step is to create a new component from the template.Microsoft provides two templates for model-driven apps: field and dataset. 
A field template is for replacing the field on the form. A dataset template is for creating a view, grid, or dataset. 
In our case, you should use the following expression (Number 1): 
 pac pcf init --namespace PCFSpace --name NewPCFComponent --template dataset 
The pac is the Power Apps CLI (pac) command for the initialization of the pcf component. The pac creates a set of files and directories. 
And the third step is to install all dependencies that you need to run your component (Number 2): 
 npm install 

After these three steps, you can code your component. 
Before you run pac and npm commands, you need to install Npm or Node.js. It is required to run Microsoft Power Apps CLI. And then, you can install Microsoft Power Apps CLI. 
All other options are incorrect.
