When should a developer consider using an elastic table in Microsoft Dataverse?

When the data is stored in an external SQL database

When the data requires complex relational queries

When the data must be accessed through a virtual table

When storing large volumes of data that do not require relational operations

A company needs to integrate its Dataverse environment with an external HR system that exposes employee data via a REST API. The HR data is read-only and must appear as a table in Dataverse so users can use it in model-driven apps and Power BI. The external API does not support change tracking or bulk operations. What should you use?

Create a virtual table that maps to the external API and configure the data source.

Use an elastic table to store the external data and update it via a custom connector.

Use a custom connector and display the data in a canvas app instead of Dataverse.

Create a standard table and use a Power Automate flow to synchronize data from the API periodically.

A company needs to store IoT sensor readings that arrive every second. Each reading is a small JSON payload. The data will be analyzed by Power BI and rarely updated. The company wants to minimize storage cost and avoid performance degradation. What should you recommend?

Store the readings in Azure Blob Storage and use a virtual table to query them.

Use a custom connector to write directly to an external database.

Use an elastic table in Dataverse to store the sensor readings.

Use a standard Dataverse table to store the readings.

A company has a Power Apps app that allows managers to approve expense reports. The approval should be recorded in Dataverse. The company wants to ensure that only managers in the Finance department can approve and that the approval history is auditable. What should you configure?

Use a business unit for Finance and grant all users in that business unit approve permission.

Create a security role for Finance managers with approve permission on the expense report table and enable auditing on the table.

Use row sharing to share each expense report with the Finance manager.

Use a Power Automate flow to send approval requests and record the outcome in a custom table.

A company has a Power Apps canvas app that submits customer feedback. The feedback must be validated (e.g., required fields, email format) before saving. The validation should work even if the app is offline. What should you use?

Use a business rule in Dataverse to validate the data.

Use a Power Automate flow to validate the data after submission.

Use canvas app formulas to validate the data before submitting.

Use a plug-in to validate the data on the server.
