Question 31.
You need to create a solution where users can scan barcodes using their mobile device camera in a canvas app. Which control should you use?
A) Barcode scanner control
B) Camera control with custom barcode library
C) Text input control with manual entry
D) Image control with upload functionality
Answer: A
Explanation:
The barcode scanner control is a built-in Power Apps control specifically designed for scanning barcodes using device cameras. This control provides native barcode scanning functionality in canvas apps running on mobile devices, supporting various barcode formats including QR codes, UPC, EAN, Code 39, Code 128, and many others. It provides a seamless, professional user experience optimized for mobile scanning scenarios.
When a user activates the barcode scanner control, it opens the device camera with specialized barcode detection algorithms that automatically recognize and decode barcodes in the camera view. Once a barcode is successfully scanned, the control returns the decoded value which can be used in your app logic to look up products, validate inventory, process transactions, or perform other barcode-dependent operations.
The barcode scanner control handles all the complexity of barcode recognition including focus, lighting adjustment, and decoding multiple barcode formats. It works consistently across iOS and Android devices in the Power Apps Mobile application and provides properties for controlling the scanning experience, handling scan results, and managing error conditions. This is the recommended approach for any barcode scanning requirement in canvas apps.
B) While you could technically use the Camera control to capture images and then implement custom barcode decoding using external libraries or services, this approach is unnecessarily complex, requires significant custom development, introduces dependencies on external services, and provides a worse user experience compared to the dedicated barcode scanner control.
C) A text input control with manual barcode entry defeats the purpose of mobile barcode scanning. Manual entry is slow, error-prone, and eliminates the efficiency benefits of barcode technology. While it could serve as a fallback option when camera scanning isn’t available, it’s not the solution for the stated requirement.
D) An image control with upload functionality would require users to first capture a barcode image using their device’s camera app, then upload it to the canvas app, and then process it for barcode recognition. This workflow is cumbersome, slow, and provides poor user experience compared to real-time barcode scanning.
Question 32.
You are developing a plugin that updates currency values on a record. The values need to be calculated using the current exchange rate. Which API should you use to retrieve the exchange rate?
A) RetrieveExchangeRateRequest
B) Query the transactioncurrency table directly
C) Use a third-party currency API
D) Retrieve the organization’s base currency
Answer: A
Explanation:
RetrieveExchangeRateRequest is the appropriate Dataverse API for retrieving the exchange rate between two currencies. This request returns the current exchange rate defined in the system for converting between a transaction currency and the base currency. It ensures that currency calculations in your plugin use the same exchange rates that Dataverse uses internally for currency field calculations.
When working with money fields in Dataverse, the platform stores values in both the transaction currency and the base currency, automatically calculating the base currency value using defined exchange rates. By using RetrieveExchangeRateRequest in your plugin, you ensure consistency between your calculations and Dataverse’s built-in currency handling, maintaining data integrity and accuracy.
The request takes the transaction currency ID as input and returns the exchange rate to the base currency. You can then use this exchange rate to convert values between currencies in your business logic. This approach leverages Dataverse’s currency management infrastructure rather than implementing separate currency conversion logic, ensuring that your plugin behaves consistently with the platform’s currency features.
B) While you can query the transactioncurrency table directly to get currency information including exchange rates, this approach requires more code and doesn’t provide the structured API that RetrieveExchangeRateRequest offers. The dedicated request is more efficient, clearer in intent, and follows best practices for working with Dataverse’s currency features.
C) Using a third-party currency API introduces external dependencies, requires managing API credentials and connectivity, creates potential inconsistencies with Dataverse’s configured exchange rates, and adds unnecessary complexity. Dataverse has built-in exchange rate management that should be used rather than external services.
D) Retrieving the organization’s base currency tells you which currency is the base but doesn’t provide the exchange rate for converting from transaction currencies to the base currency. You need the actual exchange rate value to perform calculations, which requires RetrieveExchangeRateRequest or querying the exchange rate data.
Question 33.
You need to implement a solution where a Power Apps portal displays different content based on the user’s role. Which feature should you configure?
A) Web roles with page permissions
B) Table permissions only
C) Entity forms with conditional visibility
D) Site settings
Answer: A
Explanation:
Web roles with page permissions provide the mechanism for controlling which portal users can access specific pages and content based on their assigned roles. Web roles are security constructs in Power Apps portals that group users and define what they can access within the portal. By configuring page permissions associated with web roles, you can show different pages, navigation items, and content to users based on their role membership.
When a portal user is assigned to one or more web roles, the portal evaluates page permissions to determine which pages that user can access. You can configure inheritance rules where child pages inherit permissions from parent pages, create rule-based permissions that evaluate conditions, and associate multiple web roles with different access levels on the same page. This provides flexible, role-based content display without requiring custom code.
Page permissions work in conjunction with other portal security features like table permissions (for data access) and web page access control rules. Together, these features create a comprehensive security model where you can control both what users see (pages and navigation) and what data they can access (records and fields), all based on their web role assignments.
B) Table permissions control access to Dataverse data records but do not control which pages or content users can view in the portal. While important for data security, table permissions alone don’t provide the page-level access control needed to display different portal content based on user roles.
C) Entity forms with conditional visibility can show or hide specific form elements based on conditions, but this operates at the form field level rather than controlling entire pages or content sections. This approach is too granular and doesn’t provide the comprehensive role-based page access control required.
D) Site settings are configuration values that control various portal behaviors and features like authentication providers, search settings, and feature flags. They are not designed for role-based access control and cannot determine which content users see based on their roles. They serve an entirely different purpose.
Question 34.
You are developing a canvas app that needs to display a signature pad for users to sign documents digitally. Which control should you use?
A) Pen input control
B) Text input control
C) Image control
D) Custom PCF control for signatures
Answer: A
Explanation:
The pen input control in canvas apps is specifically designed for capturing freehand drawing and signatures. This control provides a canvas where users can draw using touch, stylus, or mouse input, making it perfect for digital signature capture scenarios. The control captures the signature as an image that can be saved to Dataverse or other data sources.
When a user draws their signature using the pen input control, the control stores the signature as a data URL (Base64-encoded image). You can then save this to an image field in Dataverse using the Patch function, attach it to records, include it in generated documents, or display it for verification. The control provides properties for controlling pen color, thickness, and background, allowing you to customize the signature experience.
The pen input control handles all the complexity of touch and pointer input across different devices and browsers. It works consistently on desktop computers with mouse input, tablets with stylus input, and smartphones with touch input. The control also provides a Clear method to reset the signature pad if users want to redo their signature, making it a complete solution for signature capture.
B) Text input controls are for typed text entry and cannot capture handwritten signatures or drawings. While you could ask users to type their name, this doesn’t provide the non-repudiation and authenticity benefits of actual signature capture. Typed names are not legally equivalent to signatures in most contexts.
C) Image controls display images but don’t provide drawing or signature capture capabilities. Users would need to create a signature image externally and upload it, which is cumbersome and doesn’t provide the integrated signature capture experience needed for digital signing workflows.
D) While custom PCF controls for signatures could be developed or installed from third parties, the built-in pen input control already provides the necessary functionality for signature capture. Using a custom control adds unnecessary complexity when native functionality exists that meets the requirement.
Question 35.
You need to create a plugin that executes different logic based on whether it’s running in pre-operation or post-operation stage. How should you determine the current execution stage in the plugin code?
A) Check the Stage property of the plugin execution context
B) Check the MessageName property
C) Check the Depth property
D) Check the Mode property
Answer: A
Explanation:
The Stage property of the IPluginExecutionContext provides the execution stage information that indicates when in the event pipeline your plugin is executing. The Stage property returns an integer value where 10 represents PreValidation, 20 represents PreOperation, and 40 represents PostOperation. By checking this property in your plugin code, you can implement conditional logic that executes different operations based on the current stage.
Checking the execution stage is important when you register the same plugin class on multiple stages and want to use different logic for each stage. For example, you might perform validation in PreValidation, set calculated field values in PreOperation, and create related records in PostOperation, all from the same plugin class by branching on the Stage property value.
The execution context provides comprehensive information about the current execution environment including stage, message name, entity name, user context, and more. The Stage property specifically tells you where in the event pipeline you’re executing, allowing you to write stage-aware plugins that behave appropriately for their position in the transaction lifecycle.
B) The MessageName property indicates which operation triggered the plugin (Create, Update, Delete, custom action, etc.) but doesn’t tell you which stage of execution you’re in. A plugin could be registered on the Update message in both PreOperation and PostOperation stages, so MessageName alone doesn’t distinguish between stages.
C) The Depth property indicates how many levels deep in the plugin execution stack you are, which helps prevent infinite loops when plugins trigger other plugins. While important for recursion detection, it doesn’t indicate the execution stage. A plugin could have depth 1 in any stage.
D) The Mode property indicates whether the plugin is executing synchronously (mode 0) or asynchronously (mode 1). This tells you about the execution mode but not the stage. An asynchronous plugin always runs in PostOperation, but synchronous plugins can run in any stage, so Mode doesn’t definitively identify the stage.
Question 36.
You are implementing a solution where canvas apps need to execute complex server-side business logic that involves multiple Dataverse tables and external API calls. What approach provides the best performance and maintainability?
A) Implement all logic in the canvas app using Power Fx formulas
B) Create a custom Dataverse plugin with the business logic
C) Create an unbound custom action with a plugin for the logic
D) Use multiple Power Automate flows chained together
Answer: C
Explanation:
Creating an unbound custom action with a plugin that implements the business logic is the optimal approach for complex server-side operations that need to be called from canvas apps. This pattern provides a clean API contract through the custom action while leveraging the performance and transaction management capabilities of plugins for complex business logic involving multiple tables and external API calls.
The custom action defines the interface with clear input and output parameters, making it easy to call from canvas apps through the Dataverse connector. The plugin registered on the custom action message contains the actual business logic, which can perform multiple database operations within a transaction, call external APIs, implement error handling, and return structured results through the action’s output parameters.
This architecture separates the API contract (custom action) from the implementation (plugin), providing flexibility to change the implementation without affecting consuming apps. It ensures that complex logic executes server-side where it has full database access and transaction support, provides better performance than client-side execution, maintains security by keeping sensitive logic on the server, and allows reuse across multiple apps and integration scenarios.
A) Implementing complex logic involving multiple tables and external API calls in Power Fx formulas is inefficient, difficult to maintain, and may not be fully possible due to delegation limitations and lack of transaction support. Complex business logic belongs on the server where it can be properly managed, tested, and reused.
B) While creating a plugin with business logic is part of the solution, registering it on a standard message like Create or Update doesn’t provide a clean, dedicated API for canvas apps to call. Custom actions provide better semantic clarity, explicit input/output contracts, and clearer intent than overloading standard CRUD operations.
D) Using multiple chained Power Automate flows introduces latency, complexity in error handling, and potential reliability issues. Flows are asynchronous by nature and don’t provide the synchronous, transactional execution model needed for complex business operations. They’re better suited for workflow automation than complex business logic.
Question 37.
You need to implement a solution where users can upload and download files from SharePoint directly within a model-driven app form. Which integration method should you use?
A) Configure SharePoint document management integration
B) Create a JavaScript web resource with SharePoint API calls
C) Use Power Automate to copy files between systems
D) Create an embedded canvas app with SharePoint connector
Answer: A
Explanation:
SharePoint document management integration is the native Dataverse feature designed specifically for integrating SharePoint document libraries with model-driven app forms. When properly configured, this integration provides seamless file upload, download, and management capabilities directly within forms without requiring custom code or separate interfaces.
The integration creates dedicated SharePoint folders for each Dataverse record, automatically manages permissions based on Dataverse security roles, and provides standard document management operations like check-in/check-out, versioning, and co-authoring. Users see a familiar document grid control on forms where they can upload files by dragging and dropping, download files by clicking, and manage documents without leaving the form context.
Configuration involves setting up server-based SharePoint integration in Dataverse settings, enabling document management for specific tables, and adding the documents subgrid control to forms. Once configured, the integration handles all the complexity of authentication, folder management, permission synchronization, and document operations, providing enterprise-grade document management without custom development.
B) Creating JavaScript web resources with SharePoint API calls is a custom development approach that requires significant coding, authentication management, error handling, and ongoing maintenance. It doesn’t leverage the built-in document management capabilities that Dataverse provides and creates unnecessary technical debt.
C) Using Power Automate to copy files between systems creates data duplication and doesn’t provide the seamless in-form document experience that users need. Files would need to be managed separately in SharePoint and then manually triggered flows would copy them, creating delays, complexity, and potential synchronization issues.
D) While an embedded canvas app could provide document management functionality through the SharePoint connector, this approach is more complex than using native SharePoint integration, provides a different user experience than model-driven apps, and doesn’t leverage the built-in document management features that already exist in the platform.
Question 38.
You are developing a plugin that needs to prevent a record from being deleted if it has related child records. Which stage and mode should you use to register the plugin?
A) PreValidation stage, synchronous mode
B) PostOperation stage, synchronous mode
C) PreOperation stage, asynchronous mode
D) PreOperation stage, synchronous mode
Answer: D
Explanation:
PreOperation stage with synchronous mode is the correct configuration for validation logic that needs to prevent operations from completing. The PreOperation stage executes after security checks but before the database transaction commits, providing the perfect opportunity to validate conditions and throw exceptions that prevent the operation from proceeding. Synchronous mode ensures that the plugin executes inline with the user’s request and can block the delete operation immediately.
When your plugin detects that child records exist, you can throw an InvalidPluginExecutionException with an appropriate message explaining why the deletion cannot proceed. Because the plugin is synchronous and in PreOperation, this exception stops the delete operation before any data is modified, rolls back the transaction, and returns the error message to the user. This prevents orphaned child records and maintains referential integrity.
The PreOperation stage is specifically designed for validation and pre-processing logic that might prevent operations. It provides access to the target record information and allows queries to check for related records, while still being early enough in the pipeline to cleanly abort the operation without side effects. Synchronous execution ensures immediate feedback to users about why their operation was blocked.
A) PreValidation stage executes before security checks, which means your plugin might validate conditions for records the user doesn’t have permission to delete. Additionally, PreValidation is intended for basic data validation and default value setting rather than complex relationship validation. PreOperation is more appropriate for business logic validation involving related records.
B) PostOperation stage executes after the database transaction commits, meaning the record would already be deleted by the time your plugin checks for child records. While you could theoretically manually restore the record, this is complex, error-prone, and doesn’t cleanly prevent the operation. PostOperation is for post-processing, not validation.
C) Asynchronous mode in PreOperation doesn’t make sense because async plugins always execute in PostOperation regardless of registration. Additionally, even if it were possible, async execution wouldn’t allow you to prevent the delete operation because async plugins run after the transaction completes and cannot block user operations.
Question 39.
You need to create a solution that allows users to schedule and send automated email campaigns to contacts based on their preferences. Which Dataverse feature should you use?
A) Dynamics 365 Marketing
B) Power Automate scheduled flows with send email actions
C) Custom plugins that send emails
D) Business process flows with email steps
Answer: A
Explanation:
Dynamics 365 Marketing is the purpose-built application for creating and managing email campaigns, customer journeys, and marketing automation within the Power Platform ecosystem. It provides comprehensive campaign management capabilities including segmentation, personalization, scheduling, A/B testing, analytics, and compliance management specifically designed for marketing scenarios.
While the question asks about Dataverse features, Dynamics 365 Marketing is built on Dataverse and extends it with marketing-specific tables, processes, and user interfaces. It provides drag-and-drop email designers, customer journey orchestration, real-time marketing capabilities, and extensive analytics that would require months of custom development to replicate. For automated email campaigns based on customer preferences, this is the enterprise-grade solution.
Dynamics 365 Marketing handles all the complexity of email deliverability, spam compliance, unsubscribe management, preference centers, and tracking opens/clicks. It provides templates, dynamic content, and AI-powered optimization. For organizations serious about email marketing campaigns, this is the appropriate solution rather than building custom automation.
B) Power Automate scheduled flows with send email actions could technically send emails on a schedule, but this approach lacks campaign management, segmentation, analytics, personalization, and compliance features needed for professional email marketing. It’s suitable for simple notifications but not for full-featured marketing campaigns with tracking and optimization.
C) Custom plugins that send emails provide even less campaign management functionality than Power Automate. While plugins can trigger emails, they don’t provide scheduling, content management, segmentation, analytics, or any of the marketing-specific features needed for campaigns. This would require building an entire marketing platform from scratch.
D) Business process flows guide users through defined stages and can include email steps, but they’re designed for structured processes like sales or service cases, not for automated marketing campaigns. They require user interaction to advance stages and don’t provide campaign management, mass email sending, or marketing analytics capabilities.
Question 40.
You are developing a PCF control that needs to store component state that persists across page refreshes within the same session. Which PCF utility method should you use?
A) Use setGlobalContext to store state globally
B) Use browser localStorage API
C) Use the state parameter in updateView
D) Store state in URL parameters
Answer: C
Explanation:
The state parameter in the updateView method provides the proper mechanism for maintaining PCF control state that persists across certain scenarios. While PCF controls don’t have automatic state persistence across page refreshes in the traditional sense, the control can manage state through its internal logic and by working with the host application’s state management. The state parameter passed to updateView contains any state information maintained by the framework.
PCF controls should manage their state through proper component lifecycle methods and React/framework patterns if using a framework. For persistence across genuine page refreshes, controls typically rely on storing state in the underlying data fields they’re bound to, or by working with the form’s save mechanisms. The control’s getOutputs method is called to retrieve current state that should be persisted.
It’s important to understand that PCF controls are component frameworks meant to enhance data fields and provide custom visualizations, not to maintain independent application state. State that needs to persist across sessions should be saved to Dataverse fields. The control lifecycle methods init, updateView, and getOutputs work together to manage component state within the current session and interaction context.
A) There is no setGlobalContext method in the PCF framework. PCF controls don’t have access to global context manipulation methods that would persist state across page refreshes. State management must work within the PCF lifecycle and component model.
B) PCF controls should not directly use browser localStorage API. While technically possible, this creates state outside the Dataverse/model-driven app state management system, can cause inconsistencies, doesn’t respect security contexts, and goes against PCF design principles. State should be managed through proper PCF patterns.
D) Storing state in URL parameters is not appropriate for PCF controls and isn’t a supported pattern. PCF controls are embedded components within forms and don’t control URL routing. Additionally, URL parameters don’t provide session-persistent state management in the context of model-driven apps and embedded controls.
Question 41.
You are developing a solution that requires implementing optimistic concurrency control to prevent conflicting updates to records. Which approach should you use?
A) Check the modifiedon field before updating
B) Use the RowVersion attribute with ConcurrencyBehavior
C) Lock the record before updating
D) Use synchronous plugins on PreOperation
Answer: B
Explanation:
Using the RowVersion attribute with ConcurrencyBehavior is the proper mechanism for implementing optimistic concurrency control in Dataverse. The RowVersion is a system-maintained attribute that changes every time a record is updated. When you retrieve a record, you get its current RowVersion value. When updating, you include this RowVersion value, and Dataverse checks if it still matches the current value in the database.
If another user or process has modified the record since you retrieved it, the RowVersion values won’t match, and Dataverse throws a ConcurrencyException. This prevents your update from overwriting changes made by others without your knowledge. Your code can then catch this exception, retrieve the latest version of the record, reapply your changes or merge them appropriately, and retry the update.
To implement this in code, you set the ConcurrencyBehavior property on your UpdateRequest to IfRowVersionMatches and include the RowVersion value from when you retrieved the record. This pattern is the standard approach for optimistic concurrency in enterprise applications and is fully supported by Dataverse’s Web API and Organization Service.
A) Checking the modifiedon field is unreliable for concurrency control because it only has second-level precision, multiple updates within the same second wouldn’t be detected, and there’s a race condition between checking and updating. The RowVersion attribute is specifically designed for concurrency and changes with every update regardless of timing.
C) Dataverse doesn’t provide record locking mechanisms like traditional databases. Attempting to implement locks through custom fields or flags creates complexity, can lead to deadlocks, doesn’t handle application crashes gracefully, and goes against Dataverse’s optimistic concurrency model. The platform is designed for optimistic rather than pessimistic locking.
D) Using synchronous plugins on PreOperation doesn’t prevent concurrent updates. Multiple requests could enter the plugin simultaneously on different threads or servers. Plugins don’t provide locking mechanisms, and attempting to implement manual locks in plugins creates performance bottlenecks and reliability issues. Use the built-in RowVersion mechanism instead.
Question 42.
You need to create a canvas app that displays real-time location of field service technicians on a map. Which control should you use?
A) Address input control with static map
B) Interactive map PCF control
C) Image control with map service API
D) HTML text control with embedded map
Answer: B
Explanation:
Interactive map PCF controls are specifically designed for displaying geographic data and locations on maps within Power Apps. Several PCF map controls are available through the PCF gallery or from third parties, providing features like markers for multiple locations, real-time position updates, route display, clustering, and user interaction capabilities. These controls integrate seamlessly with canvas apps and provide professional mapping experiences.
Map PCF controls can consume location data from various sources including GPS coordinates stored in Dataverse, real-time location services, and external APIs. They support displaying multiple markers simultaneously, updating marker positions dynamically as data changes, custom marker icons for different technician statuses, and interactive features like clicking markers to show technician details.
For field service scenarios, map controls can show technician locations, customer sites, routes between locations, and service territories. They handle the complexity of map rendering, coordinate systems, zoom levels, and map tile loading. Using a purpose-built map control provides better performance, user experience, and maintainability than custom implementations.
A) Address input controls are designed for entering and validating addresses, not for displaying multiple real-time locations on an interactive map. While they may show a static preview map for a single address, they don’t support the dynamic, multi-marker, real-time mapping requirements for tracking multiple field technicians.
C) Using an image control with map service API calls would require repeatedly generating static map images and refreshing them, creating poor performance, high API usage costs, and lack of interactivity. Users couldn’t zoom, pan, or click on markers. This approach is technically possible but provides a suboptimal experience compared to interactive map controls.
D) HTML text controls display static HTML content and don’t support embedding fully interactive JavaScript-based maps with real-time updates. While you might be able to display a static HTML iframe, this doesn’t provide proper integration with Power Apps data binding, formulas, or component lifecycle, making it unsuitable for dynamic field service tracking.
Question 43.
You are implementing a plugin that needs to retrieve the current user’s business unit and manager information. Which property of the execution context should you use?
A) InitiatingUserId
B) UserId
C) OrganizationId
D) BusinessUnitId
Answer: B
Explanation:
The UserId property of the IPluginExecutionContext provides the GUID of the user under whose security context the plugin is executing. This is typically the user who initiated the operation, and you can use this ID to retrieve additional user information including their business unit, manager, security roles, and other profile data by querying the systemuser table.
Once you have the UserId, you can execute a Retrieve or RetrieveMultiple request against the systemuser table to get related information. The systemuser record includes a businessunitid lookup field pointing to the user’s business unit and a parentsystemuserid field pointing to their manager. You can use LinkEntity in your query to retrieve related business unit and manager information efficiently in a single query.
The UserId represents the effective security context for the plugin execution. All security checks, privilege evaluations, and data access filters are based on this user’s permissions. Understanding which user the plugin is running as is critical for security-aware plugins and for implementing user-specific business logic.
A) InitiatingUserId represents the user who initiated the original operation that triggered the plugin chain. In most cases, InitiatingUserId and UserId are the same. However, if the plugin calls another operation that triggers more plugins, the nested plugins have the same InitiatingUserId but might have different UserId values if the operation is executed under a different security context.
C) OrganizationId identifies the Dataverse organization (environment) where the plugin is executing. This is useful for multi-tenant scenarios or logging but doesn’t provide user-specific information like business unit or manager. You need the UserId to retrieve user profile data.
D) BusinessUnitId is a property on the systemuser and team tables, not directly on the execution context. While the executing user has a business unit, you must first use the UserId to retrieve the user record, which then contains the businessunitid field. The execution context doesn’t directly expose BusinessUnitId.
Question 44.
You need to create a Power Apps portal page that displays a form for anonymous users to submit support requests. Which type of portal component should you configure?
A) Basic form with anonymous user access
B) Entity form with create mode and anonymous access enabled
C) Advanced form with unauthenticated user permission
D) Multistep form with public access
Answer: B
Explanation:
Entity forms (now called Basic forms in newer portal versions) configured with create mode and anonymous access enabled are the proper component for allowing anonymous users to submit data through portal forms. Entity forms provide a configurable interface to Dataverse tables that can be embedded on portal pages and secured appropriately for different user scenarios including anonymous access.
When configuring an entity form for anonymous submissions, you set the mode to Insert (create), configure which fields should be displayed, set up validation rules, and critically, configure the entity permissions to allow anonymous users to create records. You also typically configure success messages or redirection after successful submission and may implement CAPTCHA to prevent spam submissions.
For support request scenarios, you would create an entity form bound to your support request table (like case or a custom table), configure the fields that anonymous users should fill out, set up entity permissions that grant Create privilege to anonymous users for that specific form, and embed the form on a publicly accessible portal page. This provides a secure, managed way for anonymous users to submit data.
A) While «basic form with anonymous user access» describes the concept correctly, option B provides the more technically precise terminology with «Entity form in create mode» and explicit mention of enabling anonymous access, which are the specific configuration steps required.
C) «Advanced form» is not standard portal terminology. The correct terms are entity forms (basic forms) or multistep forms (advanced forms). The terminology «advanced form with unauthenticated user permission» mixes concepts incorrectly. Entity forms with properly configured permissions are the standard approach.
D) Multistep forms (formerly web forms) are used for multi-page form experiences that guide users through multiple steps. While they can support anonymous access, they’re more complex than necessary for a simple single-page support request submission. Entity forms are simpler and more appropriate for single-form scenarios.
Question 45.
You are developing a plugin that needs to execute only when specific fields on a record are updated. Which feature should you use to optimize performance?
A) Filter attributes in the plugin registration step
B) Check the Target entity in plugin code
C) Use PreFilteringAttributes property
D) Register separate plugins for each field
Answer: A
Explanation:
Filtering attributes in the plugin registration step is the proper way to ensure your plugin only executes when specific fields are updated. When registering a plugin step in the Plugin Registration Tool, you can specify filtering attributes, which tells Dataverse to only trigger the plugin when one or more of those specified fields are included in the update operation.
This attribute filtering happens at the platform level before your plugin code executes, providing significant performance benefits. If a user updates fields that aren’t in your filter list, your plugin doesn’t execute at all, saving processing resources and execution time. This is far more efficient than having the plugin execute every time and checking fields in code.
When you specify filtering attributes, you select from the available fields on the target table. The plugin will only fire if at least one of the selected fields is present in the update request. This allows you to create focused plugins that respond only to relevant field changes, improving overall system performance and reducing unnecessary plugin executions.
B) Checking the Target entity in plugin code means your plugin executes for every update to the table, and then your code determines whether to proceed based on which fields were updated. This approach wastes resources because the plugin is instantiated, the execution context is prepared, and your code runs even when the relevant fields weren’t changed. Filtering attributes prevents execution entirely.
C) PreFilteringAttributes is not a property of the plugin execution context. This appears to confuse the concept with filtering attributes at registration. The execution context provides information about what triggered the plugin, but there’s no PreFilteringAttributes property. The filtering must be configured at plugin step registration.
D) Registering separate plugins for each field creates unnecessary complexity and maintenance burden. A single plugin with multiple filtering attributes is more efficient and easier to maintain than managing multiple separate plugin registrations. Dataverse allows you to specify multiple filtering attributes in one plugin step registration.
