MB-910 Describe Dynamics 365 Sales Practice Question
This MB-910 practice question tests your understanding of describe dynamics 365 sales. 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.
Your Dynamics 365 Sales instance has a custom field 'Priority' on opportunities. You want to automatically set this field to 'High' when the estimated revenue exceeds $50,000. What is the most efficient way to implement this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a real-time workflow that triggers on opportunity update and sets the field
Option C is correct because a real-time workflow triggers immediately when an opportunity is updated, allowing you to evaluate the estimated revenue and set the Priority field to 'High' if it exceeds $50,000. This is the most efficient approach as it runs synchronously without requiring user interaction or scheduled polling, and it directly modifies the field on the same record.
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.
✗
Use a business rule on the opportunity form
Why it's wrong here
Business rules set values on form, not on save.
✗
Create a Power Automate flow that runs on a schedule
Why it's wrong here
Schedule flow is not real-time and inefficient.
✓
Create a real-time workflow that triggers on opportunity update and sets the field
Why this is correct
Real-time workflow runs on save and can set field values.

Read the scenario before looking for a memorised answer.
✗
Add a calculated field that computes the priority
Why it's wrong here
Calculated fields cannot update other fields.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse business rules (client-side, form-only) with real-time workflows (server-side, event-driven), assuming both can set fields on update, but only workflows can evaluate and set fields based on conditions that trigger on record save.
Detailed technical explanation
How to think about this question
Real-time workflows in Dynamics 365 are synchronous processes that execute on the server side when a record is created, updated, or deleted, and they can include conditions and actions such as updating fields. Under the hood, they use the same event execution pipeline as plugins, ensuring immediate execution within the same database transaction. In a real-world scenario, if a sales rep updates the estimated revenue from $40,000 to $60,000, the real-time workflow fires instantly, setting the priority to 'High' before the record is saved, which is critical for timely lead prioritization.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
