Heaviest first - spend your time hereHow this exam thinks
PL-900 is a match-the-tool exam: almost every question is a short business scenario, and the right answer is the Power Platform component built for the verb in the question - automate, build an app, publish a site, or store the shared data.
Spot the trap
Tempting wrong answers, and why they failTempting but wrong
A model-driven app can bind directly to SharePoint, Excel, and Salesforce so it can combine all three on one screen.
Why it fails
Model-driven apps use Dataverse as their only data platform, so they cannot bind directly to SharePoint, Excel, and Salesforce. The app type that reaches that range of sources is a canvas app, which connects to many data sources through connectors.
Describe Microsoft Power Apps
Tempting but wrong
A Dataverse business rule is the structure that holds the rows and columns of business data.
Why it fails
A business rule is server-side logic applied to a table for validation, not a storage structure. The thing that holds a set of rows and columns, where each column stores a specific data type, is a table.

Tempting but wrong
Power Automate solutions are the prebuilt starting flows you search by scenario and then tweak to build an approval quickly.
Why it fails
Solutions are real, but they package related components so they can be moved between environments as a unit. The feature that gives a prebuilt flow you search by scenario and then modify by adding, editing, or removing triggers and actions is a template.
Describe Microsoft Power Automate
Tempting but wrong
Power Apps is the service that runs an automated workflow between two systems to re-key data and send notifications on a schedule.
Why it fails
Power Apps builds custom business applications with a tailored interface for entering and viewing data; it does not run scheduled workflows between systems. Power Automate is the service that creates automated workflows between apps and services to synchronise files, collect data, and send notifications.
Describe the Business Value of Microsoft Power Platform
Tempting but wrong
In Power Pages, the Preview template choice opens an empty site so the maker can design every page themselves.
Why it fails
Preview template only shows how a chosen template looks across devices; it previews an existing design rather than starting an empty site. The option that starts with nothing pre-built is Blank page.
Describe Microsoft Power Pages
Tempting but wrong
Model-driven apps pull in external data sources through connectors on their screens, just like canvas apps do.
Why it fails
Model-driven apps use Dataverse as their only data platform; they do not pull external sources in through connectors on their screens. It is the canvas app that connects to a wide variety of data sources through connectors.
Describe Microsoft Power Apps
Tempting but wrong
In Dataverse, a solution is what stores the rows and columns of your business data.
Why it fails
A solution packages components so makers can deploy and ship them; it does not store business data. Rows and columns of data are held in a table, which is how Dataverse organises stored data.

Tempting but wrong
Connectors are the ready-made starting flows a maker searches for a matching scenario and then edits to fit their needs.
Why it fails
Connectors are prebuilt links to apps and services, supplying the integration points used inside a flow. They are not a ready-made starting flow; the searchable, modifiable starting point is a template.

Key terms
Exam-day rules
- Read the scenario for its verb first. Automate a process, build an app, publish an external site, or store the shared data - the verb usually points straight at the one service that belongs to the question.
- Tell canvas from model-driven apps by the data and the work. Many varied sources or a hand-designed screen means canvas; data-dense, process-driven work across related Dataverse records means model-driven. This is the most tested distinction, so make it automatic.
- On flow questions, identify what starts the run. An event in a connected service means an automated trigger, a person pressing a button means instant, and a fixed clock time means scheduled.
- Watch the yes-or-no facts closely. Items like TLS versus Transparent Data Encryption, or whether sharing a model-driven app sends an email, test one precise fact - read every word and do not answer on a vague impression.
- Separate who builds from who governs. Environment Maker creates apps, connections, custom connectors, and flows; Environment Admin provisions the database and manages users. Match the role to whether the scenario builds resources or administers the environment.
