Exam MB-900: Microsoft Dynamics 365 Fundamentals Practice Test
Exam MB-900 practice focuses on foundational Dynamics 365 and Power Platform concepts used to match business needs with application capabilities. The available questions touch on model-driven and canvas apps, Dataverse records and views, Power Platform environments and connectors, and Dynamics 365 applications for retail and field service. They also include an identity-security scenario involving additional sign-in verification.
Exam overview
About the Exam MB-900: Microsoft Dynamics 365 Fundamentals Exam
Work through the scenarios by identifying the business task first, then distinguishing the component or application that supports it. For model-driven apps, this means recognizing how forms present record fields, views filter lists, and app navigation organizes pages for different roles. Dataverse questions call for understanding how tables define record structure and how rules support consistent data entry. Power Apps scenarios contrast flexible canvas interfaces with model-driven experiences; related platform concepts include environments for managing resources and connectors for linking services. Product-selection questions involve mapping operational needs—such as retail selling or dispatching technicians and managing work orders—to relevant Dynamics 365 applications. Identity questions test recognition of multifactor authentication as a safeguard against password-only access. These skills reflect basic decisions involved in discussing business-app requirements and locating the right platform capability.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A company wants to extend a Dynamics 365 model-driven app with a form that guides users through entering information for a particular record. Which component controls the layout and fields users see when they open that record?
Show answer
Correct answer: ADataverse forms define how a table’s records are presented and edited in model-driven apps, including the fields and layout users see.
An organization wants to create a governed place to build and manage Power Platform resources, with access and settings scoped for a team. What is this place called?
Show answer
Correct answer: APower Platform environments are containers for resources such as apps, flows, and Dataverse data, and can be configured to support governance and access management.
A department needs a simple app with a highly tailored screen for entering data on a phone. Which Power Apps app type is generally designed for a custom, canvas-based user interface?
Show answer
Correct answer: ACanvas apps let makers arrange controls on a flexible canvas and tailor the user experience, including for mobile scenarios.
A retailer wants to support connected in-store and online selling experiences, including retail operations. Which Dynamics 365 application is most relevant?
Show answer
Correct answer: BDynamics 365 Commerce supports retail and commerce operations across customer shopping channels.
An organization wants business users to create and edit records while applying consistent validation rules, without building a separate database application. Which Dataverse feature is most directly used to define the fields and rules for a type of record?
Show answer
Correct answer: ADataverse tables hold records, columns define the data fields, and business rules can apply validation or logic. Dashboards and workspaces are for presentation and analytics, while connectors link to other services.
A business wants to coordinate technicians who visit customer sites, including scheduling service work and managing work orders. Which application is the best fit?
Show answer
Correct answer: ADynamics 365 Field Service is designed to support on-site service operations, including work orders and technician scheduling.
A business app should show a different set of navigation items and pages to users performing different tasks. What is the most appropriate way to organize the app experience?
Show answer
Correct answer: AModel-driven apps can be organized into app modules, allowing makers to select relevant pages and navigation for particular work contexts. A tenant is an organizational boundary, and auditing is not a navigation feature.
How to use this practice test
The free practice session draws up to 20 random questions from the 50-question MB-900 bank. Use each scenario to explain why a component fits the stated task, then review the session results to identify distinctions to revisit, such as forms versus views or canvas versus model-driven apps.
Preparation tips
- For model-driven app scenarios, distinguish a form that presents one record from a view that filters and displays a record list.
- Compare canvas apps and model-driven apps by interface approach: tailored screen layouts versus experiences organized around Dataverse data.
- Review how Dataverse tables define record fields and how validation rules help keep entered data consistent.
- Map operational needs to application capabilities: retail selling and store operations differ from technician scheduling and work-order management.
- Separate Power Platform concepts by purpose: environments govern resources, connectors link services, and multifactor authentication adds a sign-in verification step.
