1. What is Slicer Filtering?

Slicer is a simple type of filtering that you can use directly on the report page. Slicers provide cues to ways you can filter the results in the visuals on a report page. There are several different types of slicers: numeric, categorical, and date. Slicers make it easy to filter all the visuals on the page at once.

2. What are the four types of filters?

The four types of filters are:

  • Report – Applies to all pages in the report.
  • Page – Applies to all the visuals on the current report page.
  • Visual – Applies to a single visual on a report page. You only see visual level filters if you’ve selected a visual on the report canvas.
  • Drillthrough – Allows you to explore successively more detailed views within a single visual.

3. What are Power Apps?

Power Apps is a suite of apps, services, connectors and data platform that provides a rapid application development environment to build custom apps for your business needs. Using Power Apps, you can quickly build custom business apps that connect to your business data. They  also provides an extensible platform that lets pro developers programmatically interact with data and metadata, apply business logic, create custom connectors, and integrate with external data.

4. What are model-driven apps in Power Apps?

Model-driven app design is a component-focused approach to app development. Model-driven app design doesn’t require code and the apps you make can be simple or very complex. In model-driven apps much of the layout is determined for you and largely designated by the components you add to the app.

5. What are the benefits of Model-driven app designs?

Model-driven app design provides the following benefits:

  • Rich component-focused no-code design environments
  • Create complex responsive apps with a similar UI across a variety of devices from desktop to mobile
  • Rich design capability
  • Your app can be distributed as a solution

6. What are the focus areas in the making of model driven apps?

Model-driven app making consists of three key focus areas.

  • Modeling business data
  • Defining business processes
  • Composing the app

7. What are the key aspects you should keep in mind while designing model driven apps?

Defining and enforcing consistent business processes is a key aspect of model-driven app design. Consistent processes help make sure your app users focus on their work and not on remembering to perform a set of manual steps. Processes can be simple or complex and often change over time.

8. What is an app module?

The term app module has been used to describe model-driven apps, and app module is the name referenced in the Microsoft Dataverse and customer engagement apps schema. 

9. What is a Trigger?

A trigger is an event that starts a cloud flow. For example, if you want to get a notification in Microsoft Teams when someone sends you an email, in this case, you receiving an email is the trigger that starts this flow.

10. In what ways can you share a flow in Power Automate?

here are three primary ways to share a cloud flow in Power Automate:

  • Add an owner to a cloud flow.
  • Share a cloud flow with run-only privileges.
  • Share a copy of a cloud flow.

11. What is a Button Flow?

Button Flows help you easily run repetitive tasks from any place, at any time. Running buttons saves you time and, since the tasks they perform are automated, there will be fewer errors than if you manually did them.

12. What are button trigger tokens?

Button trigger tokens are data points that are known and available to the device on which a button flow is running. These tokens change based on factors such as the current time or the geographic location of the device at a given moment.

13. What is AI Builder in Power Automate?

AI Builder is a new Microsoft Power Platform capability that enables you to add intelligence to your automated processes, predict outcomes, and help improve business performance. AI Builder is a turnkey solution that brings the power of Microsoft AI through a point-and-click experience and is directly integrated into Power Apps and Power Automate. 

14. What are the key benefits of entity extraction models?

AI Builder entity extraction models recognize specific data in text that you target based on your business needs. The model identifies key elements in the text and then classifies them into predefined categories. This can help you transform unstructured data into structured data that’s machine-readable. You can then apply processing to retrieve information, extract facts, and answer questions.

15. How many types of entity extraction models are there?

AI Builder features two types of entity extraction models: prebuilt and custom. Prebuilt models are ready to use, don’t require training or publishing, and are appropriate for many uses where customization isn’t needed. Custom entity extraction models must be built, trained, and published before you can use them.

16. What are the benefits of object detection model?

Object detection can help expedite or automate business processes. In retail, it can help streamline inventory management, allowing retail leaders to focus on onsite customer relationships. In manufacturing, technicians can use it to speed the repair process by quickly accessing the manual for a piece of machinery.

17. Explain Form processing Model?

Form processing lets you read and save information from standard documents such as invoices or tax documents. When you automate this process, you can save valuable time by reviewing, extracting, organizing, and saving the data automatically by using Power Automate and Power Apps.

18. Define Underfit models.

An underfit model is a model that actually performs worse than a random guess. If your model consistently performs poorly, it’s probably an indication that there’s a problem with your training data.

19. Define Overfit Models.

An overfit model appears to perform very well—if not perfectly—when run on your training data. That can be because there’s a column in your training data that directly corresponds to outcome. For example, let’s say you have a prediction model that predicts whether a shipment will arrive on time. If your historical data includes the actual delivery date, your model would predict perfectly when run against your historical data. It probably wouldn’t do so well when run on real data in your business environment, because the delivery date column wouldn’t be populated yet.

20. What are the benefits of using a no-code graphical interface?

The benefits of using a no-code graphical interface help to:

  • Eliminate the gap between subject matter experts and development teams building the bots
  • Reduce the time from when bot builders and owners recognize an issue to when it can be updated
  • Remove the need to understand complex conversational AI systems and methodologies
  • Simplify the need for complex code
  • Minimize the IT effort needed to deploy and maintain a custom conversational solution

21. Define Security Model with respect to Dataverse.

Microsoft Dataverse provides a security model that protects data integrity and privacy, and supports efficient data access and collaboration. The goals of the model are as follows:

  • Provide users with access only to the appropriate levels of information that is required to do their jobs.
  • Categorize users by role and restrict access based on those roles.
  • Support data sharing so that users and teams can be granted access to records that they do not own for a specified collaborative effort.
  • Prevent a user’s access to records the user does not own or share.

22. Define Environment.

An environment is a space to store, manage, and share your organization’s business data, apps, chatbots, and flows. It also serves as a container to separate apps that might have different roles, security requirements, or target audiences.

23. What is GDPR?

 GDPR defines personal data as any data that relates to an identified or identifiable natural person. The GDPR gives people (known as data subjects) rights to manage the personal data that’s collected by an employer, agency, or organization.

24. What is Common Data Model?

Common Data Model includes a set of standardized, extensible data schemas that Microsoft and its partners have published. This collection of predefined schemas includes entities, attributes, semantic metadata, and relationships. 

25. Describe Entities?

The primary object described by Common Data Model is the entity. An entity describes the structural shape and semantic meaning for records of data. Entities can represent physical objects, locations, interactions, individuals, point-in-time measurements, and more.

26. What are the two types of attributes?

. There are two kinds of attributes: the atomic, simple type and the more complex, composite type.

27. What are Traits?

trait is a simple object that describes a semantic meaning, settings, or measurement.

28. Describe a Polling Trigger?

A polling trigger is basically an event that periodically makes a call to your service to look for new data. Polling triggers differ from webhooks in that a polling trigger initiates an event to determine if new data is available, whereas webhooks respond to a push of new data from the service. Once the flow determines that new data is available, you can then perform an action with that data. 

29. When should Operations be versioned?

 Operations should be versioned whenever:

  • A new revision of an operation is added
  • An existing operation adds or removes parameters
  • An existing operation changes input or output significantly

30. What is the Form Processing model?

Form processing lets you read and save information from standard documents such as invoices or tax documents. When you automate this process, you can save valuable time by reviewing, extracting, organizing, and saving the data automatically by using Power Automate and Power Apps.

31. What is AI Builder receipt processor?

The AI Builder receipt processor component scans and extracts information from receipts. 

32. Define Automatic Filters?

Automatic filters are the filters that get automatically added to the visual level of the filter pane when you build a visual. These filters are based on the fields that make up your visual. Users with edit permission to the report can edit, clear, hide, lock, rename, or sort this filter in the pane.

33. What are Manual filters?

Manual filters are the filters that you drag and drop in any section of the filter pane when you’re editing a report. If you have edit permission to the report, you can edit, delete, clear, hide, lock, rename, or sort this filter in the pane.

34. How do Drill-Down Filters work?

Drill-down filters get automatically added to the filter pane when you use the drill-down functionality for a visual in your report. If you can edit a report, you can edit or clear the filter in the pane. You can’t delete, hide, lock, rename, or sort this filter because it’s associated with the drill-down functionality of visuals.

35. What are the different types of Drill-Through Filters?

Drill-through filters get passed from one page to another via the drill-through feature. They show up in the Drill-through pane. There are two types of drill through filters. The first type is the one that invokes the drill-through. If you can edit a report, you can edit, delete, clear, hide, or lock this type of filter. The second type is the drill-through filter that gets passed to the target, based on the page-level filters of the source page. You can edit, delete, or clear this transient type of drill-through filter.

36. Give some limitations of relative date range slicer.

The following limitations and considerations currently apply to the relative date range slicer and filter.

  • The data type for the field in the slicer must be a date, and not the default of text. Otherwise, the relative options don’t show up in the slicer.
  • Data models in Power BI don’t include time zone info. The models can store times, but there’s no indication of the time zone they’re in.
  • The slicer and filter are always based on the time in UTC. If you set up a filter in a report and send it to a colleague in a different time zone, you both see the same data. 

37. What do you mean by Shaping Data?

Shaping data means transforming the data: renaming columns or tables, changing text to numbers, removing rows, setting the first row as headers, and so on.

38. What do you mean by Combining Data?

Combining data means connecting to two or more data sources, shaping them as needed, then consolidating them into a useful query.

39. What is an on-premises data gateway?

The on-premises data gateway acts as a bridge to provide quick and secure data transfer between on-premises data (data that isn’t in the cloud) and several Microsoft cloud services. By using a gateway, organizations can keep databases and other data sources on their on-premises networks, yet securely use that on-premises data in cloud services.

40. What are Connectors?

A connector is a proxy or a wrapper around an API that allows the underlying service to talk to Microsoft Power Automate, Microsoft Power Apps, and Azure Logic Apps. It provides a way for users to connect their accounts and leverage a set of prebuilt actions and triggers to build their apps and workflows.
