Power Platform Fundamentals PL-900 练习

Power Apps lets makers build custom apps. Power BI is analytics, Power Automate is workflow automation, and Power Pages creates external websites.

Canvas apps give makers direct control over layout and controls. Reports, workflows, and tables are different components.

Model-driven apps are data-driven and use Dataverse tables, forms, and views. Canvas apps use freeform design, desktop flows automate desktops, and portals are websites.

Power Pages creates public-facing websites. Reports, workflows, and indexes are not websites.

Dataverse is the low-code data platform used by Power Apps, Power Automate, and Power BI. Power BI Desktop creates reports, and OneDrive or Outlook are not data platforms.

Connectors let apps and flows communicate with services. Tables, roles, and report pages are different components.

Custom connectors wrap custom APIs so Power Platform can call them. Built-in connectors are Microsoft services, and dashboards or solutions are different.

Component libraries let makers reuse UI components across apps. Schemas, workflows, and policies are different.

Solutions package apps, flows, tables, and other components for deployment. Report pages, steps, and connectors are individual components.

Canvas apps use freeform design, model-driven apps are data-driven, portals are websites, and connectors connect to sources.

Power Automate creates automated workflows. Power BI is analytics, Power Apps builds apps, and Power Pages builds websites.

Cloud flows run in the cloud and connect to online services. Desktop flows automate desktop apps, dashboards visualize data, and tables store data.

Desktop flows use UI automation to control desktop apps. Cloud flows run online, reports visualize, and roles control access.

Business process flows guide users through a defined process. Desktop automation, dashboards, and connectors are different.

A trigger starts a flow when an event occurs. Actions are steps, and reports or tables are not triggers.

Actions are steps that perform tasks in a flow. Triggers start flows, and dashboards or rows are not actions.

Scheduled flows run at defined times. Instant flows start manually, desktop flows automate desktops, and business rules validate data.

Instant flows run when a user triggers them. Scheduled flows run on a timer, and reports or views are data components.

Connectors let flows call services. Dashboards and reports visualize data, and solutions package components.

Cloud flows run online, desktop flows automate desktops, triggers start flows, and actions perform steps.

Power BI Desktop is the authoring environment for reports. Service shares reports, Power Apps builds apps, and Automate creates workflows.

Power BI Service hosts and shares reports. Desktop is for authoring, and Excel or Notepad are not Power BI sharing platforms.

A dataset contains tables and relationships used by reports. Charts are visuals, workflows are automation, and security groups control access.

Dashboards display key visuals on one page. Tables store data, flows automate, and canvas apps are applications.

Measures use DAX to calculate values dynamically. Data sources, connectors, and roles are different.

Row-level security filters data by user. It does not block all reports, hide toolbars, or delete data.

Workspaces organize and share Power BI content. Tables, workflows, and controls are not workspaces.

Gateways connect Power BI to on-premises data. Themes, chart types, and datasets are different.

Reports contain pages and visuals based on datasets. Tiles are dashboard items, workflows are automation, and columns are fields.

Desktop authors reports, Service shares them, measures calculate values, and gateways connect on-premises data.

Copilot provides AI assistance across Power Platform. It is not a database, workflow, or dashboard.

AI Builder lets makers create and use AI models. Report designers, tables, and connectors are not AI Builder.

A prompt is the input that directs AI output. Rows, steps, and pages are not prompts.

Text classification labels text into categories. Object detection finds objects in images, form processing extracts fields, and prediction forecasts values.

Form processing extracts key-value fields from documents. Text classification labels text, sentiment detects tone, and object detection finds objects in images.

Sentiment analysis judges the emotional tone of text. Language, authorship, and size are different.

Object detection locates objects in images. OCR reads text, translation converts language, and summarization shortens text.

Entities define the fields and labels a model uses. Workflows, reports, and connectors are not entities.

Generation models create text and content. Classification labels categories, prediction forecasts values, and object detection finds objects.

Copilot is an assistant, AI Builder is a platform, form processing extracts fields, and text classification labels categories.

Dataverse stores data and metadata for Power Platform. Report tools, workflow engines, and website hosts are separate services.

Tables organize records and columns. Canvas controls, dashboards, and flows are not tables.

Columns define fields in a table. Report pages, workflow steps, and security roles are different.

Relationships connect tables so data can be related. Apps, dashboards, and connectors are not relationships.

Business rules define validation and field behavior. Workflows automate processes, reports visualize, and policies govern.

Security roles define privileges. Tables store data, connectors bridge services, and flows automate.

Managed solutions package components and are hard to customize after install. Freeform apps, reports, and views are not managed solutions.

Dataverse for Teams gives Teams users low-code data and apps. Reports, desktop flows, and portals are separate.

Views display filtered and sorted rows. Workflows, dashboards, and connectors are different components.

Tables store records, columns define fields, relationships link tables, and security roles control access.

The Power Platform admin center manages environments, capacity, and policies. Power BI Desktop authors reports, Excel is a spreadsheet, and Teams is collaboration.

Environments isolate apps, flows, and Dataverse data. Dashboards, tables, and connectors live inside environments.

A tenant is the organization-level instance. Apps, tables, and report pages are inside the tenant.

DLP policies prevent data from moving between restricted connectors. Backups, workflows, and reports are not DLP policies.

Managed environments add governance, sharing limits, and analytics. Sandboxes and desktop flows are different concepts.

Capacity defines storage and request limits. Report pages, controls, and connectors consume or connect resources.

Audit logs record user and admin activities. Tables, workflows, and dashboards are not logs.

Licenses grant users access to Power Platform services. Tables, flows, and reports are content.

Sharing grants access to apps, flows, or data. Deleting, creating reports, and building connectors are different actions.

Admin center manages settings, environments isolate resources, DLP policies control data movement, and audit logs record activities.
