A. B. C. D. E.

Correct Answer: D

Dataverse provides the three types of tables (entities): Standard - this is a usual custom table type that users can create.

These tables store data and navigation for model-driven apps.

Activity - this is a special custom table type for storing activity information like appointments, phone calls, emails, tasks, etc.

Virtual - this custom table type has columns that bring data from external sources, like Azure SQL Database or Azure Cosmos DB.

Virtual tables have a list of limitations.

There are two most important limitations: data in these tables are read-only, and users cannot create or update records.

You need to use a classic interface for the creation of the virtual table.

From the Power Apps portal, you can access Advanced settings, and then on the Administration screen, select Virtual Entity Data Sources.

There you can create a new data source you would use for the virtual table creation (Number 2)

Then from the Solutions/Default Solutions on the Power Apps portal screen, you can select the “Switch to classic” option.

Portal will open the Dynamics 365 Default Solution screen.

In the menu tree, you choose Entities and push the New button on the tab toolbar.

You need to provide a name for the new table, check the Virtual Entity box (Number 1), and select a Data Source (Number 2).

It is important to remember that you cannot change the table type after table creation.

All other options are incorrect.

The correct answer to the question is D. Virtual.

When creating a new table in Dataverse, you have the option to specify the data storage mode for that table. There are two main types of storage modes available in Dataverse: standard and external. Standard tables are stored within the Dataverse database, while external tables store data in an external system and provide a virtual representation of that data in Dataverse.

In the case of the question, the table has external data storage, meaning that it is a virtual table. Virtual tables are read-only by default and can be used to access data from external sources such as SQL Server, SharePoint, or Dynamics 365.

The other answer options are:

A. Standard: This option refers to tables that are stored within the Dataverse database.

B. Relational: This option is not related to the storage mode of a table. Instead, it refers to the way tables are related to each other through common fields.

C. Activity: This option is not related to the storage mode of a table. Instead, it refers to a specific type of table that is used to track activities in Dataverse.

E. System: This option refers to system tables that are used by Dataverse to manage data and metadata.
