This MB-920 practice question tests your understanding of describe the core capabilities of the finance and operations apps. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses Dynamics 365 Finance and Operations and wants to extend the system to handle a unique business process that is not supported out of the box. What is the recommended approach?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a custom module using the extensibility framework
Option D is correct because Dynamics 365 Finance and Operations provides an official extensibility framework that allows developers to create custom modules and extend the system without modifying the source code. This approach ensures that customizations remain upgrade-safe and supported by Microsoft, unlike direct source code modifications which break the application lifecycle.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Purchase a third-party ISV solution
Why it's wrong here
ISV solutions may not cover the unique process.
✗
Use Power Apps and Power Automate
Why it's wrong here
Power Apps are for simpler scenarios, not complex processes needing deep integration.
✗
Modify the source code of Finance and Operations
Why it's wrong here
Modifying source code is not supported and causes upgrade issues.
✓
Create a custom module using the extensibility framework
Why this is correct
Custom modules built on the framework are supportable.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the extensibility framework with direct source code modification, mistakenly thinking that any customization requires changing the base code, whereas Microsoft explicitly supports only extension-based customizations for upgrade compatibility.

Detailed technical explanation
How to think about this question
The extensibility framework in Dynamics 365 Finance and Operations uses extension points such as delegates, event handlers, and chain of command to inject custom logic into existing methods without altering the base code. This approach leverages metadata and the Application Object Tree (AOT) to ensure that customizations are isolated and can be automatically merged during upgrades. A real-world scenario is adding a custom approval workflow for a unique purchase order process, where the developer creates a new module with extension classes that hook into standard purchase order events.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
