MB-920 Describe Dynamics 365 Human Resources Practice Question
This MB-920 practice question tests your understanding of describe dynamics 365 human resources. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Exhibit
Refer to the exhibit.
WorkCalendar (Name=US Calendar, LegalEntity=USMF, StartTime=08:00, EndTime=17:00, Monday-Friday)
Employee: John Doe, Position: Sales Representative, WorkCalendar: (none)
An HR administrator is reviewing the absence setup. John Doe has submitted a 1-day absence request for next Wednesday. The system shows an error that the absence duration cannot be calculated. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
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.
Refer to the exhibit.
WorkCalendar (Name=US Calendar, LegalEntity=USMF, StartTime=08:00, EndTime=17:00, Monday-Friday)
Employee: John Doe, Position: Sales Representative, WorkCalendar: (none)
A
The absence request requires manager approval first.
Why wrong: Approval is a separate step after duration is calculated.
B
The leave type is not configured for the USMF legal entity.
Why wrong: Leave type configuration affects approval, not duration calculation.
C
The work calendar is not assigned to John's position.
A work calendar is required to calculate absence duration.
D
The exhibit shows a time zone mismatch.
Why wrong: Time zone is not mentioned in the exhibit and would not cause this error.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The work calendar is not assigned to John's position.
The absence duration cannot be calculated because the system requires a valid work calendar assigned to the employee's position to determine working days and hours. Without a calendar, the system cannot compute the duration of a 1-day absence. Option C correctly identifies this as the most likely cause.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse a missing work calendar with other configuration issues like leave type setup or approval workflows, but the specific error 'absence duration cannot be calculated' directly points to the calendar assignment being missing.
Detailed technical explanation
How to think about this question
In Dynamics 365 Human Resources, the work calendar defines working days, non-working days, and working hours per day. The absence duration calculation uses the calendar to convert a date range into a numeric duration (e.g., hours or days). If no calendar is assigned to the position, the system has no basis to determine whether the requested day is a working day, leading to the calculation error. This is a common setup issue when positions are created without a calendar assignment.
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.
