The answer is that the business rule is not published or not set to run on create. This is the most likely reason because a business rule in Dynamics 365 Sales only executes when it has been explicitly activated and configured to trigger on the specific event—in this case, the creation of an opportunity. Without that configuration, the rule that should set the probability based on the estimated value simply never fires, leaving the probability field at its default 0%. On the MB-910 exam, this scenario tests your understanding of business rule lifecycle and event scoping; a common trap is assuming a rule applies automatically once saved, when in fact it must be published and its scope set to “Run on create.” Remember the memory tip: “Publish and scope—without both, your rule is a dope.”
MB-910 Describe Dynamics 365 Sales Practice Question
This MB-910 practice question tests your understanding of describe dynamics 365 sales. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
The exhibit shows a configuration snippet. A sales rep creates an opportunity with an estimated value of $15,000 but the probability remains at the default (0%). What is the most likely reason?

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Correct answer & explanation
✓
The business rule is not published or is not set to run on create
Option C is correct because a business rule that sets the probability based on the estimated value must be published and configured to run on the create event. If it is not published or not set to run on create, the rule will not execute when the opportunity is first created, leaving the probability at its default value (0%).
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.
✗
The estimatedvalue attribute is required
Why it's wrong here
Required fields do not prevent business rules.
✗
The probability attribute is set to not required
Why it's wrong here
Required level does not affect business rule execution.
✓
The business rule is not published or is not set to run on create
Why this is correct
If the business rule is inactive or not configured for create, it won't run.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

✗
The condition operator is incorrect
Why it's wrong here
The condition operator is correct for values greater than 10,000.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume the condition operator is wrong (Option D) because the rule didn't fire, but the most common oversight in Dynamics 365 is failing to publish the business rule or not setting it to run on the create event, not a logic error in the condition.
Detailed technical explanation
How to think about this question
Business rules in Dynamics 365 are client-side logic that run on form load, save, or on specific field changes, but they must be explicitly configured to run on the create event. If a business rule is not published, it remains in draft state and has no effect on any records. A common real-world scenario is when a sales manager creates a rule to auto-set probability based on estimated value tiers, but forgets to publish it or to set the scope to 'All forms' and the trigger to 'On create', resulting in the rule not applying to new opportunities.

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.
