You create a site map for your model-driven app. 
What table assets can you use for building your app?

Answer options:

A.Charts
B.Forms
C.Business Process Flows
D.Dashboards
E.Entities

Correct Answers: A, B, D and E 
The Power Apps Designer provides two types of components for creating model-driven apps: Artifacts and Table (Entity) assets. 
Artifacts include Tables (Entities), Dashboards, and Business Process Flow (Number 5). 
The Table (Entity) assets include Forms, Views, Charts, and Dashboards (Number 6). 
The designer defines the places on a canvas for placing the assets. There are several zones: Site Map with a tag for creating a Site Map (Number 1), Dashboards (Number 2), Business Process flows (Number 3), and Table (Entity) View (Number 4). 
When you select a Table (Entity) from the Artifacts, the designer allocates the tags with the name of the Table (Entity) on a canvas in Table (Entity) View zone and for all Table (Entity) Assets: Forms, Views, Charts, and Dashboards. By clicking on the asset tags, you can select more specific assets, like a particular form or a view. 

All other options are incorrect.
