Preparing for the new Microsoft Dynamics 365 exam MB-300

 In Blog

As discussed previously on this blog ( ), Microsoft is releasing a new exam schedule for business application competencies. This shift includes the introduction of the MB-300 Microsoft Dynamics 365 Unified Operations Core exam.

Recently I completed the MB-300 Microsoft Dynamics 365 Unified Operations Core exam, still in beta testing. This exam will be required for all D365FO consultants as a prerequisite to the functionality-focused exams – Financials (MB-310), Manufacturing (MB-320), Talent (MB6-898) or Supply Chain Management (MB-330).

The core exam measures your ability to accomplish the following technical tasks:

  • Use common functionality and implementation tools
  • Configure security, processes, and options
  • Perform data migration
  • Validate and support the solution

The exam is scheduled for 220 minutes, and all questions are scenario-based. You are given a scenario, either as a System Administrator, System Implementation Consultant, or as an IT Administrator.

For each scenario, you are provided specific details; then based on those details, you are asked to provide the answer(s).

Most of these scenarios have multiple questions that require an answer. Each question allows you to select from multiple options in a drop down menu, and each answer counts as a point towards your total score. Frequently, the same answer options were available for all questions in the scenario.

Some of the scenarios required the selection of multiple steps in the correct sequence to complete a process. In these scenarios, there were 5-6 potential steps to select from, and only 3 or 4 of them applied to that process. These scenarios counted as a single point towards your overall score.


To prepare, I used the following self-paced study guides available on the MBS Learn website:

  • Get started with Dynamics 365 for Finance and Operations
  • Use Lifecycle Services (LCS) to design and plan an implementation of Dynamics 365 for Finance and Operations
  • Configure your organization in Dynamics 365 for Finance and Operations
  • Dynamics 365 and Power Platform Fundamentals
  • Migrate data and go live with Dynamics 365 for Finance and Operations

I found these Learning Paths helpful- the detail for each topic is enough to understand the functionality and give some insight on what details may be in the exam, and the questions at the end of each module were helpful to validate what I had just read.

As I reviewed these study guides, I walked through each of the functional areas in a demo environment. Even though I was already familiar with most the functionality reviewed, it was great to focus on each area in more detail. Too often, we consultants look at functionality to resolve a specific customer requirement, and not always to see the full capability of that functionality.

I was able to work through these Learning Paths in about a week.

Exam Topics

Although the overall topics on the exam mostly followed the study material on MBS Learn or what was listed in the exam notes, the scenarios touched on very specific functionality that I did not see in detail in this study material. Some areas covered are not used in every implementation or are one-time setups, specifically around:

  • LCS / Business Process Libraries / User Acceptance Tests
  • Role Based Security
  • Workflow Design
  • System Administration Configurations
  • Data Management

For each of these general topics, be familiar not only with how they function, but how they are used. Because the exam is scenario-based, it’s important to understand more than just the mechanics of how each of these can function. My advice – work with them in a demo environment; configure them yourself if possible. Challenge yourself to understand how and why they can be applied in specific processes and meet potential client requirements.


At first, I thought the time provided to take this exam (220 minutes) was way more than I would need- I only used 130 minutes to take this exam. In hindsight, I should have taken more time per question to make sure I fully reviewed and worked thru each scenario. During the exam, you can flag questions and go back to them at the end of the exam; I’d recommend flagging more questions for a second review, as time permits.


This exam is still in beta testing, so my results won’t be available until “within two weeks after the exam’s live publication date.” So, we’ll all have to wait and see if this preparation worked.

Overall, I would recommend taking the time to not only read the material, but to hands-on work each of these functional areas. Make sure you are familiar with the steps to complete these tasks and see their output.

Good luck to you on this exam…
